11 September 2006Tobias Haas: JRA1 Status Preparation of Test Beam Area 24/1 for PCMAG EntranceConcrete Block as Base for PCMAG The test beam area has been renovated by MEA (Norbert Meyners). A concrete block is placed in the area as base for the PCMAG. Two holes with Ø 100mm are drilled in the floor, to access the cable trays in the cave, which connect the beam area with the control room A helium return line is installed. Carsten Muhl
