Abstract:
In LHC particles not captured by the RF system at injection or leaking out of the RF bucket may quench the superconducting magnets during beam abort. The problem, common to other superconducting machines, is particularly serious for the LHC due to the very large energy stored in the beam. A way of removing the unbunched beam has been considered which uses the existing damper kickers to excite resonantly the particles travelling along the abort gap. I will show the results of simulations and of the very first measurements done in December 2009.
