2. ALICE-TRD Status Meeting, 25.4.2005 at KIPBernd Windelband, Uni Heidelberg Fixation of SM in SF Design proposal from Münster by Wolfgang Fixation proposal from CERN by Diego Meeting on 12 th of April in Heidelberg Final decision and design

3. ALICE-TRD Status Meeting, 25.4.2005 at KIPBernd Windelband, Uni Heidelberg Fixation of SM in SF Design proposal from Münster by Wolfgang Fixation proposal from CERN by Diego Good compromise found Solution with clamped rail support more machine shop work but welding of additional parts into SF can be avoided

4. ALICE-TRD Status Meeting, 25.4.2005 at KIPBernd Windelband, Uni Heidelberg Design Work for SM Victor Chepurnov to HD end of May until end of July -> Help in detailed design of SM Wolfgang Verhoeven from Münster -> interface SF SM (rail system) Stefan Hetzel PI (CAD group) -> design of cooling/bus bar units for SM -> at present: design of 2 units for L1C1 chamber Final Design of first „full size“ SM version at PI

5. ALICE-TRD Status Meeting, 25.4.2005 at KIPBernd Windelband, Uni Heidelberg Production of L0 Backpanels Start of production: May 2nd -> L0C0 type, finished beginning of June -> L1C1 type, beg. June, finished mid July

6. ALICE-TRD Status Meeting, 25.4.2005 at KIPBernd Windelband, Uni Heidelberg Modification of L6C1 to L5C1 Backpanels One panel has been prepared and shipped to FACC. -> reduction of width by 22mm each side -> cut off longitudinal ledges of Al-frame -> milling of HC core to provide space for new ledges -> glueing in new Al-ledge both sides -> filling HC along rim with glue -> machinig the rim to required thickness -> all in all about € 400.-/panel
