Beam 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 کاملCoherent beam-beam tune shift of unsymmetrical beam-beam interactions with large beam-beam parameter.
Coherent beam-beam tune shift of unsymmetrical beam-beam interactions was studied experimentally and numerically in HERA, where the lepton beam has such a large beam-beam parameter (up to xi(y) = 0.272 ) that the single-particle motion is locally unstable at the origin (closed orbit). Unlike the symmetrical case of beam-beam interactions, the ratio of the coherent beam-beam tune shift and the b...
متن کاملImprovements in Beam-beam Tail Simulations†
Our beam-beam simulation code[1] has been improved and used to study lifetime phenomena under beam-beam interaction. One phenomenon observed is high order horizontal resonances (e. g., 8th to 16th), which are found to be exceptionally strong in the horizontal tail and have significant impact on lifetime. A first order perturbation calculation gives good agreement with the simulation on resonanc...
متن کاملBeam-beam Simulations of Hadron Colliders
Simulations of beam-beam phenomena in the Tevatron and RHIC as well for the LHC are reviewed. The emphasis is on simulations that can be closely connected to observations.
متن کاملBeam-beam Simulations with Guinea-pig
While the bunches in a linear collider cross once only, due to their small size they experience a strong beam-beam effect. Guinea-Pig is a code to simulate the impact of this effect on luminosity and background. A short overview of the program is given, with examples of its application to the background studies for TESLA, the top threshold scan and a possible luminosity monitor; as well as some...
