MACHINE PROTECTION CONSIDERATIONS FOR bERLinPro
نویسندگان
چکیده
The Berlin energy-recovery-linac project bERLinPro at the HZB is a 50MeV ERL test facility, which addresses physical and technological questions for future superconducting rf based high brightness, high current electron beam sources. The combination of a 100mA cw beam, electron bunches with normalized emittances lower than 1mm ·mrad and the magnet optics of bERLinPro leads to power densities capable to harm the accelerator components withinmicroseconds if total beam loss occurs. Furthermore, continuous beam loss on the level of 10 has to be controlled to avoid activation and to protect the SRF, beam diagnostics and other infrastructure components. In this paper, we present the evaluation of the required key parameters of the bERLinPro machine protection system and present its first conceptual design.

bERLinPro is an ERL project at Helmholtz-Zentrum Berlin, with the goal to illuminate the challenges and promises of a high brightness 100 mA superconducting RF gun in combination with a 50 MeV return loop and energy recovery [1, 2]. The precision of the beam position in a single turn machine might be relaxed compared to the demands in storage rings. Still, a trajectory correction concept has to...
متن کامل120kW RF Power Input Couplers for BERLinPro
The 50MeV, 100mA energy-recovery-linac (ERL) demonstration facility bERLinPro is currently undergoing construction at HZB. The high power injection system, that will deliver a beam at 6MeV, is split into a 1.4 cell SRF photo injector and three Cornell-style 2-cell boosters. The injector and two of the booster cavities will provide about 2MeV each and must handle up to 220 kW of beam loading. Ne...
