2. 8.7.04TRD Status meeting HdClemens Adler Production Status L1C1 Material arrived last week Glued 3 L1C1 Frames last week 1 L1C0 Frame finished Started wiring this week (Meteor switched off for last 8 cm) Try to keep up production rate of 2 Chambers per week (probably not sustainable, due to holidays)

3. 8.7.04TRD Status meeting HdClemens Adler Production Problems „Warping of Padplane panel assembly disapears when supported on all sides Wire tension measuring machine (prototype): –Very sensitve. –Position accuracy not to spec. – has problems finding all wires Holger: most problems will be soved with the“ real“ machines.

4. 8.7.04TRD Status meeting HdClemens Adler Chamber Status Finished: 3 x L1C0 (1 glued, 2 taped waiting to be tested) 3 x L2C0 (3 taped) 2 x L1C1 (mid next week)

5. 8.7.04TRD Status meeting HdClemens Adler Dead Pads David measured connection of cables on one glued panel: –2 Channels were not connected Need to measure all panels? (very time consuming)
