Abstract

Beam size estimates made using beam-beam deflections are used for optimization of the Stanford Linear Collider (SLC) electron-positron beamsizes. Typical beam sizes and intensities expected for 1996 operations are 2.1 x 0.6 mu m (x,y) at 4.0 x 10(10) particles per pulse. Conventional profile monitors, such as scanning wires, fail at charge densities well below this. The laser-based profile monitor uses a finely-focused 350-nm wavelength tripled YLF laser pulse that traverses the particle beam path about 29 cm away from the e(+)/e(-) IF. Compton scattered photons and degraded e(+)/e(-) are detected as the beam is steered across the laser pulse. The laser pulse has a transverse size of 380 nm and a Rayleigh range of about 5 mu m.
