| Title | ACHIEVING BEAM QUALITY REQUIREMENTS FOR PARITY EXPERIMENTS AT JEFFERSON LAB | ||||
| Abstract | Measurement of asymmetry between alternating opposite electron polarization in electron-nucleon scattering experiments can answer important questions about nucleon structures.Such experiments impose stringent condition on the electron beam quality, and thus the accelerator used for beam creation and delivery. Of particular concern to such ¿parity¿ experiments is the level of correlation between beam characteristics (orbit, intensity) and electron polarization that can obscure the real asymmetry.This can be introduced at the beam forming stage, created due to scraping, or not damped to desired level due to defective transport.Suppression of such correlation thus demands tight control of the beam line from cathode to target, and requires multi-disciplined approach with collaboration among nuclear physicists and accelerator physicists/engineers.The approach adopted at Jefferson Lab includes reduction of correlation source, improving low energy beam handling, and monitoring and cor | ||||
