The compton electron detector in hall A was let up to facilitate maintanance per Sirish Nanda.After the thin metal foil was installed in the detector a leak test was performed and no leaks were found. The pressure in the detector beam line is 2.7 e-05 at the turbo pump and coming down very slowly. A decision was made to pump with the turbo pump over night and try to start the ion pumps in the morning.The valves will also be re-connected in the morning. We are hoping that the material used for the shielding is not out gassing.
Figure 1 is shows the pressure vs. time in the compton line.
