A Luminosity Monitor Using the CoherentBeam { Beam Interaction ( Internal Report )
نویسندگان
چکیده
A new method of monitoring the luminosity has been developed at CESR. The method involves shaking one bunch at a speciic frequency and observing the resulting oscillations of the corresponding opposing bunch. In initial tests, measurements with 1% accuracy have been obtained in 1 second. Measurements of diierent bunches in a train shows bunch to bunch diierences with the optimum luminosity conditions for one bunch not coinciding with the optimum for another.

Design of an NLC Intrapulse Feedback System
The small beam spot size at the interaction point of the Next Linear Collider (NLC) makes the luminosity sensitive to beam jitter. A mechanism for aligning the beams to each other which acts during the bunch-train crossing time (~260 ns) has been proposed to maintain luminosity in the presence of beam jitter. Conceptual designs of principal components of the system, a fast position monitor, a k...
متن کاملPin–Hole Luminosity Monitor with Feedback∗
Previously, the generalized luminosity L was defined and calculated for all incident channels based on an NLC ee design. Alternatives were then considered to improve the differing beam-beam effects in the ee, eγ and γγ channels. Regardless of the channel, there was a large flux of outgoing, high energy photons that were produced from the beam-beam interaction e.g. beamsstrahlung that needs to b...

KEKB has transformed to an effective head-on collision by using of crab cavities from a crossing collision and gained a higher specific luminosity. A gated beam-position monitor, being capable of measuring the beam phase as well as the transverse position of a specific bunch in a bunch train, has been developed and is used to measure a beam-beam kick. The monitor estimated the effective horizon...
متن کاملNlc Luminosity as a Function of Beam Parameters †
Realistic calculation of NLC luminosity has been performed using particle tracking in DI-MAD and beam-beam simulations in GUINEA-PIG code for various values of beam emit-tance, energy and beta functions at the Interaction Point (IP). Results of the simulations are compared with analytic luminosity calculations. The optimum range of IP beta functions for high luminosity was identified. Abstract ...
