Techniques for determining electron losses at a 1.5 GeV synchrotron light source.
A computer code was developed to simulate the bremsstrahlung dose rate distribution patterns produced by the CAMD electron storage ring. These bremsstralung dose rate distributions were measured along the interior surface of the shield walls (short walls perpendicular to the bending magnets) with TLD chips. Electron losses for each specific magnet was determined by running the computer code and varying the electron loss parameters to fit the measured dose rate distributions. It was determined that (1) bending magnet No. 1 (closest to the injection septum) loses 2.7 x 1010 electrons per minute during electron injection. The loss rate for each of the subsequent seven bending magnets during injection varies from about 25% to 33% of this number; (2) the magnet immediately subsequent to the bending magnet loses more electrons than the magnet immediately prior to the bending magnet does; and (3) the computer code may be used to predict potential problems such as misalignment.
