Successful Coating Tests


By admin - Posted on 31 May 2016

In early May, the MMTO staff completed two full scale coating system tests. Utilizing the bell jar assembly at base camp, the coating system provided a 1050 Å thick coating (recorded at the two center deposition monitors that correspond to the center of the primary mirror) on May 4 and a 1150 Å thick coating on May 11. This critical milestone in preparation for the 2016 primary mirror realuminization was the first time all ten filament arrays containing the new style filaments had been fired using the MMTO-developed control software.
