Abstract :
An analytical treatment of quadrupole misalignment effects are presented for the Argonne Advanced Photon Source (APS) 200-MeV electron linac. The results of numerical modeling with TRANSPORT are discussed. It is shown that the capture of the positrons into the pulsed solenoid located after the positron production target depends on how well the electron beam is centered on that target. If the electron beam spot is displaced from the center of the target by delta p, in order to have a 90% capture, delta p should be approximately 0.1 d (d=beam diameter).<>
