Experimental Station
The primary advantage of the TRXAS end-station is its ability to record complete X-ray absorption spectra simultaneously and rapidly. This makes it an ideal tool for in-situ measurements to monitor structural and electronic changes in samples under various environmental conditions, such as high temperature, pressure, or specific gas atmospheres.
In-situ Environmental System
Currently, the institute provides a specialized Heating Cell designed to support a wide range of in-situ research applications, enabling simultaneous temperature control and atmospheric regulation.

Detector System
To measure XAS spectrum, the position sensitive detector (PSD) is used.
S3904–1024F
NMOS Linear Image Sensor
with Scintillator
(Hamamatsu Photonics K.K.)
NMOS linear image sensor consisting of 1024 pixels of an N-type diffusion layer formed on a P-type silicon substrate.
Detection Method
The use of an indirect detection method, employing an X-ray scintillator (150 μm thick CsI (Cesium Iodide) coated on a fiber optic plate) to convert X-rays into visible light, extended the sensor lifetime to over a year.
