Installation and calibration of a new device for studying the thermal desorption of hydrogen isotopes from materials

Thermal desorption spectroscopy is a method typically used in surface science to study the kinematics of desorbing species from a material. Typically the sample is heated in a linear heating rate and the desorbing species are detected by a mass spectrometer during the heating. The candidate would build the set-up, calibrate the mass spectrometer to gain absolute amounts of desorbing species. Once the set-up would be commissioned the candidate would study hydrogen desorption from materials like tungsten where our group has a lot of experience.
