PEM injections and scattering tests

Lance, Genevieve, Robert

Today during the commissioning period we made shaker injections at EX, as part of the redo of the formal pre-run PEM injections because of the reduced vibration coupling at 60W. We are getting near the end of these re-dos. We also made some injections at EX and LVEA to understand coupling of the EX water pump to DARM and to investigate the dewar fill noise at the Y-manifold cryopump.
