Modification of the code BEAMCORR, and some simulation results of the magnet and achromat misalignments for the SLC South Arc

Description: An important decision has been made regarding the correction scheme for the arcs leading to the adoption of the so called scheme I. In this scheme the beam position data are collected from single-plane x and y Beam Position Monitors (BPMs), which are placed in the drift spaces adjacent to the downstream D- and F-magnets correspondingly. Similarly, single-plane x and y correctors are used for moving the upstream end of the corresponding magnets. In the present simulation this scheme is used excl… more

Temperature rise in iron beam position monitors

Description: This note presents the results of EGS calculations for the temperature rise in an iron beam position monitor strip in the SLC arcs for a 50 GeV incident electron beam. Temperature rises of about 830/sup 0/C per pulse are possible for 50..mu.. (Gaussian sigma) beams of 5 x 10/sup 10/ electrons per pulse if the angle of incidence is great (i.e., around 30 mradians).

Novel probe for determining the size and position of a relativistic electron beam

Description: In order to determine the size and position of a relativistic electron beam inside the wiggler magnetic field of a Free Electron Laser (FEL), we have developed a new probe which intercepts the electron beam on a high Z target and monitors the resulting bremsstrahlung radiation. The probe is designed to move along the entire three meters of the wiggler. This FEL is designed to operate in the microwave region (2 to 8 mm) and the interaction region is an oversized waveguide with a cross section 3 … more
