DESCRIPTION:Speakers: Stanislav Serednyakov (Budker Institute Of Nuclear P
 hysics)\nThe Novosibirsk Free Electron Laser (FEL) is based on a 4-turn mi
 crotron-recuperator. To ensure its stable operation and radiation generati
 on\, it is necessary to provide a stable mode of electron beam recirculati
 on and minimize beam losses on the vacuum chamber wall on all the way of b
 eam in the accelerator beamline.  To fulfil this task it is necessary to k
 now the longitudinal distribution of these losses along the beamline.\nTo 
 this end\, a system for registration of beam losses was created. The syste
 m applies optical fibers placed along the full length of the vacuum chambe
 r and nearby it. In case of local electron beam losses somewhere in the va
 cuum chamber\, electrons falling to the vacuum chamber wall cause generati
 on of X- and gamma rays. This radiation in turn causes generation of optic
 al radiation in the optic fiber nearby the region of electron “precipita
 tion” on the chamber wall. Then\, executing some transformation and proc
 essing of the time dependencies of signals from these optic fibers\, one c
 an obtain the longitudinal distribution of electron beam losses along the 
 whole accelerator channel in all its 4 turns.\n\nhttps://indico.inp.nsk.su
