Simulation of the beam halo from the beam-beam interaction.
SLAC-PUB-6379 October 1993 W Simulation of the Beam Halo from the Beam-Beam Interaction T. Chen, J. Irwin and R. Siemannt Stanford Linear Accelerator Center, Stanford University, Stanford, CA94309 Abstract: A new technique for simulating the beam halo in circular e+ecolliders is introduced, tested, and applied. Amplitude space is divided into core and halo regions, and only halo particles are t...
متن کاملStudy of Beam - Beam Effects at PEP - II ∗
Using a self-consistent three-dimensional simulation running on parallel supercomputers, we have modeled the beam-beam interaction at the PEP-II asymmetric e+e− collider. To provide guidance for luminosity improvement, we scanned the tunes and currents in both rings and computed their impact on the luminosity and transverse beam sizes. We also studied the effects of colliding the beams with a s...
متن کاملNonlinear f Method for Beam - Beam Simulation
We have developed an e cacious algorithm for simulation of the beam-beam interaction in synchrotron colliders based on the nonlinear f method, where f is the much smaller deviation of the beam distribution from the slowly evolving main distribution f0. In the presence of damping and quantum uctuations of synchrotron radiation it has been shown that the slowly evolving part of the distribution f...
متن کاملPanel Discussion on Beam-beam Simulation Codes∗
I present a brief summary of my remarks made at the Panel Discussion on Beam-Beam Simulations (Session 4A) held at the First CARE-HHH APD Workshop on Beam Dynamics in Future Hadron Colliders and Rapidly Cycling High-Intensity Synchrotrons “HHH 2004” (CERN, 8-11 November, 2004). PRELIMINARY QUESTIONS It does not seem easy, in general, to benchmark beambeam simulations against experiments, whethe...
متن کاملNumerical simulation of laser beam welding of Ti6Al4V sheet
This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The butt-joint welds were made using CO2 laser with the maximum power of 2.2 kW in the continuous wave mode. A part of the experimental work was carried out to verify the weld geome...
