1 Bakeout Control and Heater Systems Matthew Bohman ALPHA Collaboration University of Michigan Semester at CERN

2 ALPHA Antihydrogen Laser Physics Apparatus Goals: Create and trap antihydrogen Perform spectroscopy on antihydrogen Explore antisymmetries in matter and antimatter Test CPT violation

3 Antimatter and Vacuums Antimatter and Annihilations: Need low pressure to in order to effectively trap antiprotons and positrons Given an estimated gas temperature of 10K and the length of of the experiment at 15 minutes, a pressure of better than 8e-13 mbar is needed.
