WebMotivation for applying electron cooling for the bunching process • Recent studies showed that for minimal momentum spread which can be achieved in ELENA p/p =2.5·10-4 (Gerard Tranquille) beam capture and compression to get required bunch length 4 l = 1.3m can be made fast, approximately within 50 msec (Steve Hancock). WebApr 11, 2024 · To achieve the electron cooling, the beam quality, i.e., emittance and energy spread, is to be precisely characterized and optimized. The high-power PC has been operated in the 1 Hz pulsed mode to pick up one single optical bunch for producing one single electron bunch in the DC gun.
Webenergy RHIC cooler with bunched electron beams. Unfortunately, a similar approach to low-energy RHIC cooling using a DC electron beam faces several problems. First is the problem of accumulating secondary ions in the electron beam potential which affects its angular spread, although this can be alleviated by providing small gaps in WebThe U.S. Department of Energy's Office of Scientific and Technical Information
