Beam-beam Simulations with Non-gaussian Distributions for Slc and Slc-2000
نویسندگان
چکیده
Due to various upstream beam manipulations, the longitudinal bunch shape at the interaction point of the Stanford Linear Collider (SLC) is highly non-Gaussian. In this paper, we report beam-beam simulations with realistic longitudinal bunch shapes for the present SLC parameters and for the SLC-2000 luminosity upgrade. The simulation results allow us to estimate the luminosity enhancement due to the pinch effect and to find optimum parameter settings for the bunch compressor and the linac.

Beam-based Feedback Testing and Simulations for the SLC Linac *
Beam-based feedback systems were a key element in the successful operation of the Stanford Linear Collider (SLC) but the performance was not optimal. Some limitations were incomplete communication between the feedback loops, slow correctors, and constraints on the placement of feedback devices. Recent beam experiments and simulations have improved our understanding of feedback performance chara...
متن کاملUsing a Fast-gated Camera for Measurements of Transverse Beam Distributions and Damping Times*
With a fast-gated camera, synchrotron light was used for studying the &&verse bean-i distributions and damping times in the Stanford Linear Collider (SLC) damping rings. By digitizing the image in the camera signal, the turn-by-turn time evolution of the transverse beam distribution was monitored and analyzed. The projections of the digitized image were fit with Gaussian ftinctions to determine...

Beam dynamics issues affect many different aspects of the SLC performance. This paper concentrates on the multi-particle beam dynamics in the linac and the associated limitations that are imposed on the overall SLC performance. The beam behavior in the presence of strong wakefields has been studied in order identify ways to optimize the performance and to predict the expected emittances in high...
متن کاملThe Steered Auxiliary Beam Canceller for Interference Cancellation in a Phased Array
A common problem encountered in phased array signal processing is how to remove sources of interference from a desired signal. Two existing methods to accomplish this are the Linearly Constrained Minimum Variance (LCMV) beamformer and the Side-Lobe Canceller (SLC). LCMV provides better performance than SLC, but comes with much higher computational costs. The Steered Auxiliary Beam Canceller (SA...
متن کامل-survey of Beam Instrumentation Used in Slc*
A survey of beam instruments used at SLAC in the SLC machine is presented. The basic utility and operation of each device is briefly described. The various beam instruments [l] used at the Stanford Linear Collider (SLC), [2,3] can be classified by the function they perform. Beam intensity, position and size are typical of the parameters of beam which are measured. Each type of parameter is impo...
