Vacuum design of storage ring and front ends

Conference · · AIP Conf. Proc.; (United States)
OSTI ID:6775951

The vacuum chambers of the 2.8 GeV BEPC storage ring consists of Al alloy 6061 extrusions as the bending magnet chambers, all stainless steel flanges and roll bond Al/SS clad metal as the transitions. The double-decker distributed ion pumps were designed to have pumping speeds of >0.16 m/sup 3/.s/sup -1/.m/sup -1/, and are mounted inside the slotted Al extrusions. To improve the vacuum at the interaction region, additional radial ion pumps and NEGs would be connected with the beam pipe.
