Cryogenic facility at our service
After the fabrication of a cavity, the cavity is cooled to 4,2K then at 1,8K where, the Q-factor is measured as a function of the accelerating field.
A 4 meters deep cryostat for the rf test of 1,3 Ghz 9-cell resonators. By a 20,000 cubic meter/hour roots pumping, the cryostat will support 60 watts of RF powers.
A four-chamber sputtering system. Having a central turbopump that serves four different chambers insulated by 4 all-metal CF40 Right angle valves, thus the system enables four people to work almost simultaneously.
Germanium thermometers, silicon diodes or carbon glass thermometers are employed for monitoring the cavity temperature in the cooled liquid helium bath.
