Thin radiator running conditions

This page contains a list of running conditions that might be impacted by a switch from running with a 60 micron converter at 150nA beam current, and running with a 20 micron convertr of comparable quality at 450nA beam current, both with the same 5 mm primary collimator. All of these can be measured by putting the thick and thin radiators into the beam, before either one has been fully characterized, eg. orientation for polarized running has been performed.

1. background hit rates in the CDC
2. background hit rates in the FDC
3. bias in the active collimator position
4. singles rates in the TAGH and TAGM
5. singles rates in the PS counters
6. neutron fluxes in the tagger hall (affects SiPM, electronics lifetime)
