eg1 commissioning |
|
|
08/21 - 12/24 |
run eg1 (for 91 days) |
1) The g1 run extension will restore most of the time lost at the beginning of the g1 run (g1 was supposed to start 04/13/98). Three-pass beam will not be available, since it is occupied by Gen in Hall C. The 1.83 GeV (2-pass) beam energy had originally been arranged for eg1. At 1.83 GeV, one will get perfect longitudinal polarization (at the 75% level). While this energy is too low for some of the g1 experiments, it will represent a unique opportunity to get circularly polarized photons with high polarization, e.g. for measuring the polarization transfer from circularly polarized photons to photo-produced Lambda's.
