2.3 General Overview
The Surface Concept 19” HVPS Detector Supply R020 is a 1 channel high voltage module especially
designed for the Surface Concept 19”Basic Unit, a modular supply system.
The 19” HVPS Detector Supply R020 is laid out for the operation of e.g. MCP based detectors with metal
anode or CEM detectors. It provides one single high voltage with a positive polarity. It also provides the
capability to oat on an external reference potential.
The 19” HVPS Detector Supply R020 comes with a maximum output voltage of +3000V and can oat on
voltages of up to +/- 1000V. Check the specication sheet of your specic 19”HVPS Detector Supply R020
for further specic information.
The device can produce lethal high voltages of up to several kV. Hazardous voltages are
present, therefore only persons with the appropriate training are allowed to carry out
the installation, adjustment and repair work.
Do not open the power supply, while it is in operation. Hazardous voltages are present.
In case that the device must be opened, turn o the device rst AND pull out the power
plug.

3 Introduction
3.1 Initial Inspection
Visual inspection of the system is required to ensure that no damage has occurred during shipping. If
there are any signs of damage, please contact SURFACE CONCEPT immediately. Please check the delivery
according to the packing list (see Table 1) for completeness.
• 1x 19“ HVPS-HV Module R019
• 1x SHV Termination Plug
Table1: Packing list for the 19“ Basic Unit R019.
3.2 Installation
The general connection scheme of the 19”HVPS-HC Module R020 is as follows:
Figure 1: Connection scheme of the 19” HVPS Detector Supply R020 (the detector ange is given for illustration only.
Please check the manual of your MCP/CEM detector for the correct ange layout and feedthrough assignment).

Finish the complete cabling of the 19” HVPS Detector Supply R020 before switching on
the 19” Basic Unit and switch o the device rst before performing any changes to the
cabling.
• Install the 19”HVPS Detector Supply R020 into a free slot of the 19”Basic Unit (if not already installed).
• High voltage output is provided to the SHV socket named“MCP-B”.
• The socket named“MCP-F”connects the external reference voltage which is given to the device via the
“HV Ref. In” input to the front side of the MCP stack/ CEM of the detector
• Use SHV cables to connect the outputs of the 19”HVPS Detector Supply R020 to the corresponding HV
input/s of the MCP/ CEM detector (see your MCP/ CEM detector manual for more details).
• Use the SHV termination plug to terminate the “HV Ref. In” input when not working with an external
reference voltage.
Note
In cases that no reference voltage is applied to the device, the termination plug must be
used to ground the reference input of the 19”HVPS Detector Supply R020. With a missing
reference potential the device is not providing any output voltage.

4 Device Layout & Operation
4.1 Device Layout
The layout of the 19” HVPS-HC Module R020 is given below.
1. SHV connector for output of operation voltage for a
MCP/CEM detector.
2. SHV connector for output of reference potential to
the front side of a MCP/CEM detector.
3. SHV connector for input of an external reference
potential (max. +/- 1,000V, check with your MCP
or CEM detector manual for details on maximum
reference potentials).
Figure 2: Layout of the 19”HVPS Detector Supply R020.
The 19” HVPS Detector Supply R020 is specied for the operation with an external
reference voltage of maximum +/- 1,000 V (see no. 3 in Figure 2).
Please also respect the corresponding specications for the maximum voltage for the
MCP front potential of your MCP/CEM detector (see the manual and the specication
sheet of your MCP/CEM detector for further details).

4.2 General Device Operation
After switching on the 19” Basic Unit, its display shows the “Surface Concept” animated logo, while the
device is scanning for the 19” HVPS Detector Supply R020 and its specic settings. This can take up to
several seconds. If the 19” Basic Unit is ready for operation, it switches into the standby mode and shows
an empty mask for the voltage adjustment (see Figure 3).
Push the“Start/Standby” button in the lower left
corner of the display to switch on the high
voltage.
Alternatively one can press the“Channel”control
knob.
After switching on the high voltage the device
is in the so called operation mode. In operation
mode the display shows the name of the selected
channel in the top line (in this case“HV 1”) as well
as the output voltage of that channel.
The dierent HV channels can be selected by
turning the “Channel” control knob.
Figure 3: Standby mode.
Figure 4: Operation mode.
Figure 5: Operation mode – voltage adjustment.
The “Adjust” control knob is used to adjust the
output voltage. Turn the “Adjust” control knob
clockwise/counterclockwise to increase/decrease
the value of the output voltage in a step width as
dened in the line “edit step”.
The line “set value” displays the nominal value
for the output voltage as adjusted by the user.
Voltage adjustment can only be made in this line.
The line “actual” displays the actual value for the
output voltage on the output connector as measured by the device.The device always regulates the actual
value of the output voltage to t to the nominal value as set by the user. Hereby the voltage measurement
is always a relative measurement between the two HV outputs of one channel. Additional reference
voltages (e.g. in oating operation) are not measured and therefore are also not displayed (see the manual
of the specic module for further details). Turn the“Adjust”control knob clockwise/counterclockwise while
pushing it to increase/decrease the step width in the line “edit step”.
Push the„Start/Standby“-button in the lower left corner of the display again to switch back to
the “Standby” mode.

4.3 Operation of a MCP/CEM Detector
In some cases a MCP detector is operated with the front side of the MCP stack terminated to ground. But
for many other applications it is necessary to apply some external reference voltage to the front side. In
this case the oating capability of the 19” HVPS Detector Supply R020 allows a more insusceptible supply
of the correct detector operation voltage because the external reference voltage must not be taken into
account for the MCP operation voltage. Additionally this wiring also saves the detector intrinsically from
any over-voltage in case of a sudden drop of the external reference voltage. In general there are three
dierent application cases concerning reference potential to the front side of the detector’s MCP stack.
For example: Assume an operation voltage of a detector of +1,900V.
Application case 1: The detector should be operated with the MCP front side connected to ground. In
this case the SHV termination plug is connected to the “HV Ref. In” input. “MCP-B” is set to the detectors
operation voltage. The display shows a value of MCP-B = 1,900 V. The output voltage in respect to the
ground potential is MCP-B = +1,900 V.
Application case 2: The detector should be operated with the MCP front side connected to +1000V. In this
case the external reference voltage is connected to the “HV Ref. In” input. First set the 19” HVPS Detector
Supply R020 to the detectors operation voltage. Then increase the external reference voltage to the
+1,000V. The display shows a value of MCP-B = 1,900V, but the output voltage in respect to the ground
potential is MCP-B = +2,900V.
Application case 3: The detector should be operated with the MCP front side connected to -500V. In this
case the external reference voltage is connected to the “HV Ref. In” input. First set the 19” HVPS Detector
Supply R020 to the detectors operation voltage. Then increase the external reference voltage to the -500V.
The display shows a value of MCP-B = 1,900V, but the output voltage in respect to the ground potential is
MCP-B = +1,400V.

and measuring resistors.
4.4 Schematic Layout of the 19” HVPS Detector Supply R020
Figure 6 shows the schematic layout of the 19” HVPS Detector Supply R020 and especially the layout of
the HV outputs. An internal controller measures the output voltage and regulates it to the nominal value
entered by the user or set as default value within the device. Hereby the voltage measurement is always a
relative measurement. The output polarity is xed dened (see the specic specication sheet for details
on the max. output voltage and the polarity). The device comes with an integrated 2-fold fan-out for the
output voltage of each channel. Figure 6 also shows the internal load and measuring resistors.
Note
The 19”HVPS Detector Supply R020 is not producing any output voltage if the reference
input “HV Ref. In” is not terminated (either to ground or to an external HV potential),
because the HV module always need to be connected to a reference potential. A SHV
termination plug is part of the delivery to terminate the “HV Ref. In”input to ground.
