LowLossSapphireWindowsforHighPowerMicrowaveTransmission（十一）
Fixture Testing. Fixture testing consisted of vacuum, heating, pressure, and microwave testing.Pressure Testing. Initial pressure testing of thin sapphire windows in a fixture was conducted on both halves of the standard fixture that had been fabricated with thin windows in Phase I. The sapphire windows were 76 mm diameter, 0.325 mm thick that were matt finished on one side and epi-polished on the o......閱讀全文
