Temperature Programmed Desorption Secondary Ion Mass Spectrometer


The original project provided by Sandia National Laboratory is to design, fabricate, and install a new sample holder and ionization mechanism. The sample holder must be re-designed to hold a larger, stainless-steel sample that could be compatible with temperature programed desorption (TPD). The ionization mechanism must be compatible with the current NAU time-of-flight (TOF) mass spectrometer system. It is required that the sample and the ionization source are aligned properly in order to test the systems performance. Overall, the main goal of this project is to modify the current sample holder for use of TPD of a stainless-steel sample.
