Studies of the Beam-beam Interaction at Cesr
The Cornell Electron Storage ring facility CESR operates with 2 GeV multi-bunch electron and positron beams in a single beam-pipe. Electrostatic separators are used to separate the two counter-rotating beams at the parasitic crossings. When the beam energy was lowered from 5 GeV in 2003, the strength of the beam-beam interaction became a more important factor in beam-current limitations, result...
متن کاملWakefields and HOMs Studies of a Superconducting Cavity Module with the CESR Beam*
Several aspects of the beam-cavity interaction were investigated in a beam test of the superconducting accelerating cavity module for the CESR upgrade: the time structure of the cavity wake potential, sampled with two bunches, the effect of the module on the total machine loss factor, and the influence of the cavity tuner position on the frequencies and damping times of coupled bunch modes. The...
متن کاملThe streak camera development program at LLE
The Diagnostic Development Group at the Laboratory for Laser Energetics has endeavored to build a stand-alone, remotely operated streak camera with comprehensive autofocus and self-calibration capability. Designated as the Rochester Optical Streak System (ROSS), it is a generic streak camera platform, capable of accepting a variety of streak tubes. The system performance is limited by the insta...
متن کاملBeam - Generated Detector Backgrounds at CESR ∗
The CESR/CLEO Phase II interaction region is described. The operational experience with beam-generated detector backgrounds is reviewed. The status of our understanding of beam-generated detector backgrounds at CESR is described and comparisons of background measurements with simulation predictions are presented.
متن کامل“Crystal Collimator” Measurement of CESR particle-beam Source Size
We have measured electron and positron beam source size at CHESS when the Cornell Electron Storage Ring (CESR) is run dedicated for the production of synchrotron radiation. Horizontal source size at several beamlines is expected to shrink by a factor of two but synchrotron (visible) light measurements only provide the vertical size. Therefore a “crystal collimator” using two Bragg reflection in...
