Notes from this meeting:

• The quarter cryo-unit RF gradients were found to be lower by 5%. However, during the September test, we set the energy using the dipole so we should be very close to the quoted energy. Complete analysis of the beam energy measurements is forthcoming.

• Ernst is calculating bubble chamber sensitivity to gamma ray flux. Previous experiments obtained a limit of <10^-11 with a gamma radioactive source.
