ante. Assurez-vous que les zones où l'azote liquide est utilisé sont bien aérées pour éviter le
déplacement de l'oxygène dans l'air.

DXF Getting Started Guide Page 8
1Wear goggles or a face shield, thermally insulated gloves large enough to be removed easily, and a
rubber apron. For extra protection, wear high-topped, sturdy shoes, and leave your pant legs outside the
tops.
2Transfer the liquid slowly to prevent thermal shock to the equipment. Use containers that have satisfactory
low-temperature properties. Ensure that closed containers have vents to relieve pressure.
Thermal Safety
If the power has not come back on after a power failure, do NOT open the furnace. The temperature con-
trollers will not be displaying a temperature so you will not know what the temperature is inside the fur-
nace.
The test is over once a power failure occurs. This is no recovery method to restart the test at that point, but
all data is saved up until the power failure occurs.
Do not press any buttons on the front panel after a power failure, just start a test normally. If the test was
running under vacuum, verify the vacuum.
Chemical Safety
WARNING: Cryogenic blow back possible if dewar is rapidly filled with liquid nitrogen. Fill par-
tially and allow for initial boil-off prior to filling completely.
AVERTISSEMENT: Possibilité de projections de gaz très froid si le Dewar est rapidement rempli
avec de l'azote liquide. Remplir partiellement et permettre une évaporation initiale avant de rem-
plir complètement.
DANGER: Source instrument surfaces can be hot enough to cause discomfort when in contact
with the skin during a sample run. If you are conducting a subambient test, cold could also
cause injury. After running any type of experiment, you must allow the DXF system to return to
near room temperature before you touch the inner furnace surfaces. Always use the available
software monitor to display temperature even after the termination of the test cycle.
DANGER: Les surfaces de l'instrument source peuvent être assez chaudes pour provoquer un
malaise au contact de la peau pendant l'analyse d'un échantillon. Si vous effectuez un essai à
basse température, le froid peut également provoquer des blessures. Après avoir effectué un
type d'expérience quelconque, vous devez laisser le système DXF revenir à la température
quasi ambiante avant de toucher les surfaces internes de la four. Utilisez toujours le moniteur
logiciel disponible pour afficher la température même après la fin du cycle d'essai.
WARNING: In the event of a power failure, do NOT open the furnace.
AVERTISSEMENT: En cas de coupure de courant, N'ouvrez PAS le four.
WARNING: Do not use hydrogen, oxygen, or any other explosive gas in the DXF system. Only
inert gas, such as nitrogen or argon, should be used.
AVERTISSEMENT: N'utilisez pas d'hydrogène, d'oxygène ou tout gaz explosif dans le système
DXF. Seuls les gaz inertes comme l'azote ou l'argon doivent être utilisés.

Introducing the Discovery Xenon Flash
Overview
Thermal diffusivity () is the thermophysical property defined as a ratio of the thermal conductivity and
the volumetric heat capacity. The thermal diffusivity in SI units is cm2/s. The most popular method used
for measuring thermal diffusivity is the flash method. It has the advantage of being fast while providing
values with excellent accuracy and reproducibility. The flash diffusivity method involves uniform irradia-
tion of a small, disc-shaped specimen over its front face with a very short pulse of energy. The time-tem-
perature history of the rear face is recorded through high-speed data acquisition from a solid-state optical
sensor with very fast thermal response, and thermal diffusivity is determined from the time-dependent ther-
mogram of the rear face. Thermal conductivity can be calculated as a product of the thermal diffusivity, the
specific heat, and the density of the material. A Discovery Xenon Flash (DXF) system automatically deter-
mines the thermal conductivity using the measured (or separately entered) specific heat capacity and ther-
mal diffusivity, with separately-entered density data.
The DXF system is comprised of a DXF Pulse Source, Environmental Module, IR Detector Assembly, and
associated software.The DXF with EM 200+ is shown below.

Your controller is a computer that performs the following functions:
• Provides an interface between you and the analysis instrument.
• Enables you to set up experiments and enter necessary information.
• Stores experimental data.
• Allows data analysis of results.
NOTE: For technical reference information, theory of operation, and other information associated with the
DXF system not found in this manual, see the online help associated with the instrument control software.
DXF System Components
A DXF system has three major components: the DXF Pulse Source module, the Environmental Module
with Detector Assembly, and the controller.
Pulse Source Module
The Discovery Xenon Flash (DXF) covers the most commonly needed cryogenic to 900°C temperatures
with a range of Environmental Modules, and employs a High Speed Xenon-Pulse Delivery Source
(HSXD). The reflective optic configuration effectively harnesses the power of a Xenon flash tube, and,
with the aid of proprietary wave guides, delivers it to the sample inside the Environmental Module. The
DXF produces a maximum pulse width of 650 s while uniformly concentrating sufficient power from the
flash source directly on the entire face of the sample. This optimized energy gathering scheme and the
broad light spectrum allows samples as large as 25 mm in diameter to be illuminated with sufficient
energy.
