Description

New e+e- accelerator designs plan to have polarized beams. Precision detectors located very close to the beam envelope will be needed to measure the polarization of the stored bunches. In addition, the new designs call for multi-Ampere stored beam currents. This will move electron and positron storage ring designs into new territory with the need of detectors this close to these high-current beams. I will discuss issues of synchrotron radiation backgrounds for low-angle detectors in general and suggest possible means of controlling these backgrounds.
