Line 17: − + − * All safety classes and eye exams have been taken, the [[Media:S.O.P.pdf|S.O.P.]] is nearly ready for filing.+ − * The laser has been transferred to Dr. Barry Wells' lab and placed on a reinforced table.+ − * The main exhaust and vacuum pump exhaust are installed. − * The HV power supply is connected to the laser head and hooked up to the mains (208V 3-phase) − * Gas lines have been installed with new Swagelok fittings. − * Gas solenoids have been repaired and the system has been charged with fresh Helium to 2600mbar. − * Currently the system is leaking >25mbar per hour and we plan on replacing o-rings in main laser window to fix this. − * Optics will be cleaned once we receive our new supplies and the laser must be realigned using a HeNe laser. − * A Veeco Helium Leak Detector was used to check for leak sites. The front window has the largest source of Helium at the moment and the o-ring will be replaced shortly. Also, a number of the "spark plugs" that discharge into the laser had noticeable leak rates and I hope to service them shortly.
