CHAPTER 1
Introduction to the VSM Oven Option
1.1 Introduction
This chapter contains the following information:
○Section 1.2 is an overview of the VSM
Oven option.
○Section 1.5 outlines safety considerations
for working with the VSM Oven option.
○Section 1.3 describes notable features
of the VSM Oven option.
○Section 1.6 lists contact information at
Quantum Design and its service centers.
○Section 1.4 describes the VSM Oven
option theory of operation.
1.2 Overview
The Oven for the VSM provides a way to make sensitive D.C. magnetometry measurements at
controlled temperatures from 300 K up to 1000 K. Using a specially designed heated sample
holder and VSM sample rod with electrical feedthrough, the VSM Oven vibrates the sample
inside the VSM detection coilset. Both the standard VSM option and a high-vacuum option are
required in order to operate the VSM Oven.
Heating of the sample is achieved by applying current to a Platinum resistive heating element
lithographically patterned onto the custom-designed sample holder. A thermocouple embedded
on the back side of the sample holder measures the temperature in the sample region, and a
thermistor at the top connector of the sample holder corrects for heating of the cold junction. In
this manual, we will refer to the VSM Oven sample holder as the heater stick (see Figure 5-1). To
maximize thermal contact, the sample is attached to the heater stick using alumina-based cement
(included in VSM Oven Option User’s Kit, Figure 5-5). Then, the platinum heater region is
wrapped securely with a thin copper-foil radiation shield that retains heat and reduces thermal
gradients between the sample and heater stick.
The VSM Oven heater region is a 1 inch long heated substrate on which the sample is glued. This
design is in contrast to that of other high-temperature oven inserts for magnetometers, which
often are bulky and have long thermalization times. By embedding the thermometry in the
substrate along with the heater, we have made vast improvements on typical thermal-response
times and sample-temperature accuracy. Due to the low thermal mass of the heated substrate, you
can maintain heating rates at the sample of over +200 K/min throughout the full temperature
range of the oven. Note that the cooling rate will depend on the current temperature of the heater
stick, because cooling occurs through thermal radiation from the heater stick to the VSM
detection coilset.

Theory of Operation Introduction to the VSM Oven Option
1-2 VSM Oven Option User’s Manual, Rev. A3 Quantum Design
May 2011
Ease of use is another advantage of the Quantum Design VSM Oven option—it uses the same
VSM detection coilset as the standard (low temperature) mode of the VSM option. To change
from the standard VSM mode to the VSM Oven mode, you simply insert a different sample rod
into the VSM.
1.3 Notable Features of the VSM Oven Option
Figure 1-1 illustrates the hardware and functional connections necessary for operating the VSM
Oven. A new CAN module, the Model CM-C VSM Oven module, has been introduced to handle
the temperature control of the VSM Oven heater stick. This module plugs into the Model 1000
Modular Control System, which communicates with the PC via the CAN network cable. The
oven-control cable plugs into the front panel of the oven-control module. This cable passes heater
power and temperature readback information to the heater stick via the electrical feedthrough on
the wired access port and the wired oven sample rod.
Figure 1-1. Operating principle for the VSM Oven option
1.4 Theory of Operation
The platinum heater is driven synchronously to the power line frequency (50 Hz or 60 Hz,
depending on country and region) with a sinusoidal excitation. Magnetic feedthrough from the
heater currents into the VSM detection coilset is minimized by patterning the heater
noninductively and by operating at line frequency, where the VSM detection circuitry can easily
reject the signal. The thermocouple voltage is monitored constantly by a sensitive low-drift DC
microvolt preamp in the VSM Oven module. The thermocouple junction is located in the middle
of the heater region of the stick, and the thermocouple wires terminate at the connector at the top
of the stick. Note that the thermocouple table is referenced to a cold junction at 273 K (0 ºC).
Also located at the connector is a negative temperature coefficient thermistor that corrects for the

Chapter 1 Section 1.4
Introduction to the VSM Oven Option Theory of Operation
Quantum Design VSM Oven Option User’s Manual, Rev. A3 1-3
May 2011
thermocouple cold junction temperature. The thermistor is read about 10 times a second using a 2
msec current pulse.
The temperature at the sample Tsample is calculated from the thermocouple voltage
 VTC and
thermistor resistance Rthermistor as follows:
Tsample = TTC(VTC + V(T(Rthermistor))),
where
T(Rthermistor) = standard table for temperature vs. thermistor resistance,
V(T) = standard table for type S thermocouple voltage vs. temperature standard, and
T(V) = inversion of the V(T) thermocouple table.
In order to enable temperature control down to 300 K at the heater stick, the VSM puck is set to
295 K while the system operates in VSM Oven mode. Due to the heat load from the heater stick
when it is at high temperatures, the software lets the block temperature go as low as 283 K while
it tries to maintain the puck temperature at 295 K.
Figure 1-2 below shows a simplified schematic of the control circuit for the heater stick. “PID”
refers to the Proportional-Integrator-Differential temperature control of the A.C. drive for the
heater.

Section 1.6 Chapter 1
Safety Precautions Introduction to the VSM Oven Option
1-4 VSM Oven Option User’s Manual, Rev. A3 Quantum Design
May 2011
1.5 Overheating Prevention Mechanisms
To safeguard the equipment from overheating, the coilset temperature is set to 295 K while it is
operating in oven mode, and the VSM Oven software uses the VSM coilset temperature as the
primary diagnostic. In the event that the VSM coilset temperature rises above 350 K, the system
shuts down the power to the oven heater.
1.6 Safety Precautions
WARNING!
The VSM Oven option is used in conjunction with the Physical Property
Measurement System (PPMS) family of systems, so you should be aware of
the safety considerations for that equipment. PPMS-related safety precautions
may include those for the use of superconducting magnets and the use of
cryogenic materials (if applicable).
Above all, Quantum Design and its staff ask that you use standard safe laboratory procedures.
Use common sense.
Pay attention to the state of the system and to your surroundings.
Investigate and take appropriate action if the behavior of the system appears abnormal—
something could be wrong with it.
Supervise inexperienced users and train them in laboratory safety and in general electrical
safety procedures.
The VSM has safety features to prevent accidents from causing injury or serious equipment
damage. If you use the equipment in a manner that is not specified by Quantum Design, the
protection afforded by the equipment may be impaired.
1.6.1 VSM High-Temperature Heater
Handle the heater stick with caution when you remove it from the cryostat.
The heater stick should be near room temperature by the time you take it from the wired access
port—it has very low mass (less than 1 gram of hot material) and cools substantially when the
sample chamber is vented with helium gas. Yet, you should remember that the central region of
the heater stick can reach temperatures up to 727 °C (1000 K), and this would cause severe burns
if you touched it.

Chapter 1 Section 1.6
Introduction to the VSM Oven Option Safety Precautions
Quantum Design VSM Oven Option User’s Manual, Rev. A3 1-5
May 2011
1.6.2 Cryogens
WARNING!
Always wear protective clothing and ensure that the room has good ventilation
when you work with cryogenic materials such as liquid helium and liquid
nitrogen. These precautions will help protect you against cryogenic material
hazards: (1) they can expand explosively when exposed to room temperature;
(2) they can cause serious burns.
Always wear protective clothing, including thermal gloves, eye protection, and covered
shoes, when you work with liquid helium, liquid nitrogen, or other cryogens. Avoid loose
clothing or loose fitting gloves that could collect cryogenic liquids next to the skin. The
extreme cold of liquid and gaseous cryogens can cause serious burns and has the potential to
cause loss of limbs.
Work with cryogenic materials only in well-ventilated areas. In the event a helium container
ruptures or there is a helium spill, vent the room immediately and evacuate all personnel. In a
poorly ventilated area, helium can displace the air, leading to asphyxiation. Because helium
rises, it is generally safest to work with it in well-vented rooms with high ceilings.
1.6.3 Magnets
WARNING!
Any person wearing a pacemaker, electrical medical device, or metallic implant
must stay at least 5 m (16.5 ft.)1from the dewar. In addition, personnel must
keep all ferromagnetic objects at least 5 m (16.5 ft.) from the dewar. Verify that
magnetic fields are at zero (0) before handling the VSM linear motor transport in
any way.
The following precautions should be followed to ensure the safety of personnel who work with or
around a superconducting magnet. This material is covered in more depth in main system user
manaul.
Verify that any person who has a metallic implant or is wearing a pacemaker or electrical or
mechanical medical device stays at least 5 m (16.5 ft.) from the dewar. Large magnetic fields
are dangerous to anyone who has a metallic implant or is wearing a pacemaker or other
electrical or mechanical medical device.
Important: The automated control system can turn on the magnet while the system is
unattended. Furthermore, the three-dimensional magnetic field will penetrate nearby walls,
the ceiling, and the floor. Therefore, your safety considerations should include such adjacent
spaces.
1At the current time, 5 m should be a large enough distance to protect wearers of metallic implants or medical
devices from most magnetic fields produced by Quantum Design magnets. However, the safe distance from
newer magnets (in development) could be greater. Hence, personnel who work with and around the
superconducting magnets should thoroughly review documentation for new equipment.

Section 1.7 Chapter 1
Contacting Quantum Design Introduction to the VSM Oven Option
1-6 VSM Oven Option User’s Manual, Rev. A3 Quantum Design
May 2011
Keep all iron, nickel, and other ferromagnetic objects at least 5 m (16.5 ft.) from the dewar.
Large magnets, such as superconducting magnets, can attract iron and other ferromagnetic
materials with great force.
Never attempt to install, remove, or handle the VSM linear motor transport when there is a
field set in the cryostat or in any other nearby equipment. In addition, the VSM linear motor
transport must be secured when it is stored within 5 m (16.5 ft.) of the cryostat or any other
large field source. The VSM linear motor transport presents a considerable hazard in a large
magnetic field such as that produced by the cryostat or other laboratory equipment such as an
NMR magnet, as the linear motor transport contains nearly 9 kg of iron.
1.6.4 Electricity
WARNING!
The VSM is powered by nominal voltages between 100 V to 240 V AC. These
voltages are potentially lethal, so you should exercise appropriate care before
opening any of the electronics units, including turning off the equipment and
disconnecting it from its power source.
Turn off and unplug all electronic equipment before removing any equipment covers.
Keep electrical cords in good working condition and replace frayed and damaged cords.
Keep liquids away from the workstations.
1.7 Contacting Quantum Design
If you have questions or problems related to your QD equipment, please contact your local QD
service representative. See www.qd-international.com for information about your location
representative. You will be asked to describe the problem, the circumstances involved, and the
recent history of your system.

2.3 Initial Installation of the VSM Oven Option
Important: The instructions in this section are only to be used the first time the VSM Oven
hardware and software is installed on the system (for example, if the oven hardware was just
purchased as an upgrade to an existing system). For routine installation and removal of the oven
hardware, see Section 2.4.
The VSM Oven hardware requires the following items to be present and operational on the
system:
oStandard VSM hardware and control modules, see the VSM Option User’s Manual
oHigh Vacuum option, see the PPMS Cryopump User’s Manual (PPMS only)
oCAN network adapter and Model 1000 Modular Control System, see the Model 1000
User’s Manual (PPMS only)
oUp-to-date EPROMs in the Model 6000 (version 1.914 or later) (PPMS only)
To initially install the VSM Oven option on the system, follow these steps:
1) Deactivate any active options and close the MultiVu program
2) Turn off power to the CAN control tower
3) Insert the VSM Oven Module CM-C into a slot in the CAN control tower
4) Turn on the CAN control tower
5) In the file C:\Qdxxx\Vsm\System\VSM.INI (where xxx is Ppms, VersaLab, or
DynaCool), open in Notepad and ensure that this line exists WITHOUT any semicolon
(;) at the beginning of the line:
OVEN TYPE=1;
6) Save the VSM.INI file and close Notepad
7) To install remaining elements of the VSM oven hardware, continue to Section 2.4.
2.4 Installing the VSM Oven Hardware
It is assumed that the VSM hardware is installed on the cryostat before the following steps are
taken, see the VSM Option User’s Manual for information on installing the VSM hardware.
