Higher order effects in beam-beam deflection

SLAC - PUB - 5221 January 1 f ! $ HIGHER ORDER EFFECTS IN BEAM - BEAM DEFLECTION *

Beam-beam deflection scan is a useful tool, both in the SLC and in future linear colliders, for extracting information about the beam position, .w size and luminosity. This technique poses nontrivial challenges to the instrumentation in its own right. The understanding of all aspects of beam-beam deflection, in particular that of disruption, is therefore crucial to a successful implementation o...

Beam-deflection optical tomography.

We report two-dimensional density measurements in a supersonic expansion using beam-deflection optical tomography. Quantitative, high-resolution images with absolute accuracy to 3.5% and spatial resolution to 50 microm were taken with a helium-neon laser and simple apparatus.

Beam-beam Deflection as a Beam Tuning Tool at the Slac Linear Collider

To achieve maximam integrated luminosity at the SLAC Linear Collider, a method of noninvasive beam tuning is required . Traditional luminosity monitors based on Bhabha scattering are inadequate because of low instantaneous counting rates. Coherent deflections of one beam by the electromagnetic field of the other are sensitive not only to the relative steering of the two bunches but also to thei...

Beam-deflection optical tomography of a flame.

We report three-dimensional index-of-refraction measurements in a methane-air slot diffusion flame and a methane-air slot subsonic jet using beam-deflection optical tomography. The horizontal and vertical spatial resolutions are 0.26 and 0.635 mm, respectively. The peak temperature is calculated from the index-of-refraction map for the flame and compared with thermocouple temperature measurements.
