Beam Line Vacuum System

Vacuum for the entrance beam line is supplied by 65 $\ell$/s Balzers turbo pumps, the first of which is located on the E P chamber, and the second located 3 $m$ upstream of the target chamber. Both turbos are equipped with a HPS 7 Series 275 mini Convectron gauge and a HPS series 421 Cold Cathode gauge located near the balcony.

Vacuum readouts and relay outputs for interlocks are supplied by HPS series 421 Cold Cathode gauges. In addition to these there will also be Convectron gauges. Most of this instrumentation will be located on the Turbo pump manifold.

Powered valves, instrumentation and pumps will be controlled and powered at the Vacuum System equipment rack located on the Balcony. Selective equipment will also be monitored from the Hall A counting house. All control is by Accelerator in the MCC.
