Line 11: − + − The following is a list of tasks required to get the Ar-F excimer laser online.+ − * First, take the proper safety course required by the University of Connecticut Environmental Health and Safety department. − * Prepare Dr. Well's laboratory for the transfer of the Excimer laser including setup of ventilation, three-phase (208V) power supply, cold water distribution and collection, and a sturdy table to put the laser on. − * Replacement of Halogen Filters − * Tend to the vacuum system: replace oil in diffusion pump, test for serious leaks at moderately low pressure (10−6 Torr) − * Test the RF generator (most expensive/hard to replace!) − * Procure a bottle of pure Ar gas − * Check internal circulating fan bearings, as these are a possibly source of corrosion − * Flush the tube, turn it on and test output power − * Barring major repair: expected online by end of 2009 with $2-3k − Long-term operating goals: − * Switch optics to 192nm − * Get mixture of Ar-F, eventually procure a gas mixing system) − * Ensure reliable pulse train and consistent power output (±5%)
Diamond Radiator Thinning Using an Excimer Laser (view source)
Revision as of 02:27, 13 December 2016
, 02:27, 13 December 2016→Work Schedule
Laser ablation will be used to thin the diamond chip to the precise thickness required for the radiator. An older excimer laser offered by a local AMO group will be converted from a XeCl 308 nm beam to the required ArF 193 nm beam. Although the system was last used 10 years ago, it was left in a fully functioning state and was properly flushed upon decomposition. There may also be another unused excimer laser that can be used for parts in case any repair is needed. I have included a link to my current [http://zeus.phys.uconn.edu/wiki/index.php/Pratt Lab Journal] which I plan to update bi weekly.
