Abstract
The behavior of dynamically polarized targets in the presence of a hig h intensity electron beam was studied. The nuclear polarization seen b y the incident electron beam is lower than the overall measured target polarization by NMR due to beam heating and subsequent depolarization . A correction for this beam-induced depolarization is developed here to correct the measured target polarization for these effects. Further more, a model has also been developed to calculate the target depolari zation in beam, and optimization of running conditions for future expe riments of this nature are discussed based on this model.
