Electron Beam Probe Diagnostic for BESSY II Storage Ring
A low energy electron beam can be used to characterize the high energy ultra-relativistic bunches. This technique allows one to obtain the bunch transverse profiles as well as the bunch length within a non-destructive single shot measurement. In this paper the bunch length measurement technique based on the interaction of the low energy electron beam with an ultra-relativistic bunch is describe...
متن کاملBeam Lifetime Dependence on the Beam-Gas Interactions in RHIC
In the Relativistic Heavy ion Collider (RHIC) much larger background signals were occurring at BRAMS, one of the four experiments. This was especially pronounced at the time when vacuum conditions deteriorated due to the beam ionization profile monitor replacements. Recording the beam intensities during the store provided the beam lifetime. Predictions from the beam gas interactions to the abov...
متن کاملLaser-Electron Storage Ring
A compact laser-electron storage ring (LESR) is proposed for electron beam cooling or x-ray generation. The LESR uses an intense laser pulse stored in a highnesse resonator to interact repetitively with a circulating electron beam in the energy range from a few MeV to a few hundred MeV. The rapid damping caused by laser-electron interaction counterbalances the intrabeam scattering e ect, thus a...
متن کاملElectron Beam at Intermediate Pumping Rates
XeF( C --* A ) laser radiation has been produced in a fivecomponent gas mixture excited by a coaxial electron beam with an intermediate pulse length ( 175 ns) and pumping rate ( 1 MW/cm'). The laser output energy was 215 mJ from an active volume of 157 cm3 (1.4 J / L ) at a total gas pressure of 8 bar corresponding to an intrinsic
متن کاملVacuum Conditioning and Beam Lifetime of the Spring-8 Storage Ring
The installation of the vacuum system of the SPring-8 storage ring was completed during 1996. Most of the vacuum chambers are made of aluminum alloy. The main pumping system is a mixed one consisting of NEG strips, DIP, SIP, and LNP. In addition to the standard treatments for ultrahigh vacuum components, dust-controlled procedure was adopted in the manufacturing and the installation processes. ...
