TI - Advances in CW Ion Linacs J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Substantial research and development related to CW proton and ion accelerators are being performed at ANL. A normal conducting CW RFQ and a 4K cryomodule with seven quarter-wave resonators (QWR) and SC solenoids have been developed, built, commissioned and operated as an upgrade of the CW ion linac, ATLAS, to achieve higher efficiency and beam intensities. The new CW RFQ and cryomodule were fully integrated into ATLAS and have been in routine operation for more than a year. Currently we are engaged in development of the first cryomodule for a CW H linac being built at FNAL. This work is well aligned with the development of a 1 GeV 25 MW linac as the driver of a sub-critical assembly for near-term spent nuclear fuel disposal. A 2K cryomodule with eight 162.5-MHz SC half wave resonators (HWR) and eight SC solenoids is being developed for FNAL and scheduled for commissioning in 2017. The testing of the first 2 HWRs demonstrated remarkable performance. Experience with the development and reliable operation of new copper and superconducting accelerating structures is an essential precursor for advanced, reliable future large scale high power CW accelerators.
