Equipment
Xenon Flash
Thermal diffusivity measurements
This equipment is also available to external users.
For measurement requests and scheduling, please contact the equipment operator via email (pjy010128@postech.ac.kr).
Service requests only; direct use is not permitted.
It is essential to ensure that the sample remains stable and does not affect the surrounding environment in any way (including, but not limited to, evaporation) within the measurement temperature range.
If the equipment is damaged due to such effects from the sample, the requester will be fully responsible for the cost of component replacement.
Requesters are strongly advised to consult with the equipment operator in advance regarding the charateristics of the sample to be measured.
The exact thickness of the sample must be provided, and the sample surface should be flat and uniform in height.
Sample size requirements: 10 mm diameter disk or 12.7 mm diameter disk.
Failure to meet these conditions may result in measurement errors.
