Items of Discussion
-----------------
S. Benson pointed out that we will need to be careful of stray fields after the cryounit to prevent them from interfering with the very weak quad fields.
The 60 pC case actually looks better with the 135 pC lattice than the 135 pC case. The alphas and betas do change, however, so the FEL turn-on transition would be to set up the 5 mA energy recovered beam and then lase, once the beam parameters go to the predicted values.
Lia asked how the longitudinal emittance varies with the bunch charge and Byung said he wasn't sure; he'd need to model the case.
She also pointed out that to fill in the sensitivity spec table she will work with Byung's PARMELA sensitivity studies. The specs are her first priority and she is trying to have them ccomplete by next Tuesday.
