Abstract
HEBT BNL NC Linac LANL Front End LBNL The SNS linac will deliver a 1 GeV proton beam for injection into its accumulator ring. The normal conducting section of the linac has the RFQ and drift tube linac (DTL) powered by seven 2.5 MW, 402.5 MHz klystrons and the coupled cavity linac (CCL) powered by four 5.0 MW, 805 MHz klystrons. The superconducting section of the linac employs eighty one 6-cell cavities power by eighty one 550 kW, 805 MHz klystrons. In the tunnel after the successful commissioning of the front end, three DTL tanks, two CCL modules, and eight medium-beta cryomodules have been installed. Corresponding high voltage converter modulators (HVCM) and low level rf (LLRF) control systems have been installed and tested.
