Maintenance for CMP-11

Compressor arrived, new, with npt fittings for the cooling water and no receptacle for the main power.  Swagelok fittings and a short pigtail for the power were added at TRIUMF.  The cryopump Helium charge was exchanged with new gas and compressor was installed in the appropriate location inside the BNMR cage under the magnet.  System was commissioned after repositioning the cooling water inlet and outlet since on the previous Austin compressor they were reverse in position on the compressor box.  Within 1.5 hrs, the system showed 6 Kelvin.  This is a false low reading, but it is consistent with the assumption that the silicon diode in the cryopump is faulty which was evident with the previous Austin compressor.
