Moxtek is a company from Orem, UT that specializes in x-ray detectors that are primarily used for elemental analysis (x-ray spectroscopy). The detectors have a window that maintains vacuum inside the detector, while allowing x-rays to pass through. The current detectors use a beryllium window that is able to withstand high heat, but absorbs a high percentage of very low energy x-rays. A getter is used inside the X-ray detector that once activated, will absorb trace gas molecules, maintaining high vacuum over the life of the detector. To activate, the getter is heated to 350 °C in a vacuum chamber for many hours before the detector is sealed. While the getter is being heated, all the parts of the x-ray sensor are heated as well. Moxtek is replacing the current Beryllium window on the x-ray sensor with a polymer window that cannot take the temperatures achieved with an oven heating method, so a new method of heating the getter is necessary.

Moxtek has asked BYU Capstone Team 23 to design a method to heat the getter to 500 °C while preventing the window and other components from reaching a high temperature. By raising the temperature limit, the duration of the getter activation will decrease several hours to 10 minutes. The getter must be heated evenly to 500 °C for ten minutes while the other sensor components are kept below at approximately 150 °C. The team used a 6 watt laser that was split to direct the energy to different parts of the getter, consequently achieving a more consistent temperature across the getter. An optical feed-through was placed into the vacuum chamber instead of an electrical feed-through to allow the laser to be cooled outside the vacuum.
