dc.description.abstractEnA new heating and gas treatment line for Thermo-Desorption Spectrometry (TDS) of noble gases (He, Ne, Ar, Kr and Xe) is presented. It was built with the primary objective to offer advanced temperature controls and capabilities while working in a cold-environment. By choosing a high-power continuous wave laser as an heating source, and using a Proportional-Integral-Derivative (PID) controller system, noble gases TDS can now be performed with fast and highly steady heating ramps (e.g. less than 1°C deviation from setpoint for ≤ 1°C.s-1 ramps). Sample temperature over 2000°C can also routinely be reached, with limited heating of the sample support and the sample chamber, offering the possibility to have several samples awaiting in the ultra-high vacuum chamber. We also present development efforts made to increase temperature homogeneity of the heated sample while limiting contacts with the sample holder. Recent results acquired with this TDS setup on krypton thermal diffusion in uranium dioxide (UO 2) as a function of O 2 additions are also presented as an application example.
