Target Vacuum System

Vacuum for the target chamber is supplied by an Alcatell 880 $\ell$/s Turbo pump backed by an Alcatell 21 $cfm$ 2 stage vane pump. The Turbo is mounted on the lower ring of the Target Chamber to one side so as not to interfere with the Target Chamber windows.

The same instrumentation is used here as on the spectrometer.

Powered valves, instrumentation and pumps will be controlled and powered at the Vacuum System equipment rack located on the access Balcony. Selective equipment will also be controllable from the Hall A counting house.
