Beam Dynamics in Slc

چکیده

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 performance linacs. Emittance measurements and simulations are presented for the SLAC linac and are compared in detail. As the overall SLC performance depends on the accelerator stability, the tuning stability is discussed. Results are shown and the consequences for the performance of the SLC are discussed.

Simulation of Bunch Precompression at High Currents in the Slc Damping Rings

In the Stanford Linear Collider (SLC) each beam, after leaving a damping ring, is compressed in the Ring-to-Linac (RTL) transfer line before entering the linear accelerator. At a bunch population of 4:0 10 particles, due to the limited energy acceptance of the RTL, approximately 15% of the beam has normally been lost. During the 1996 run, however, to eliminate this loss the bunch was partially ...

Experimental Beam Dynamics and Stability in the Slc Linac*

J. T. SEEMAN, R. JACOBSEN, R. K. JOBE, and M. C. ROSS Stanford Linear Accelerator Center, Stanford University, Stanford, CA 94309 _ Abstract The SLC linac must produce stable high energy, low emittance beams to make maximum luminosity. The incoming beam conditions must be correct and stable. The trajectories of the two beams must be controlled to about 100 pm. The energy and energy spectrum of ...

Beam-beam Simulations with Non-gaussian Distributions for Slc and Slc-2000

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...

-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...

The 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...
