Description
We would like to invite you to take part in the HIE-EBIS workshop at CERN on 16-17 October 2012. The workshop is devoted to the considered upgrade of the charge breeder for the REX-ISOLDE facility at CERN. The demanding requirements of the new machine pose some challenges such as combining high magnetic field strength (superconductive magnets at 6-7 T), an electron beam with high energy (150 keV), high current (2-5 A) and high density (up to 105 A/cm2) with extremely high vacuum of about 10-13 mbar. We have invited and received positive responses from specialists working with the best performing EBIT/S devices worldwide (including LLNL, BNL, MSU/NSCL, MPIK, JINR, ANL, University of Frankfurt and University of Electrical Communications Tokyo). Our intention is to bring together the experience of the invited EBIT/S experts with knowledge of CERN specialist in magnetic, vacuum and cryogenic technologies, accelerator and ion source physics. There will be plenty of information to learn, as well as many points to discuss and give a feedback to, in order to advance the development of the HIE EBIS project. We are looking forward to seeing you at CERN to share the new ideas, recent technological advances and scientific results amongst the EBIT/S community.
