1. 10/7/2003Thomas Schneider1 Status report of CERN/PNPI Tooling support for PNPI M2R2 Prototype Plans towards the PRR

2. 10/7/2003Thomas Schneider2 Tooling support for PNPI 4 gluing tables 1 wiring machine + 6 sets of combs + 10 pair of panel holders 1 quality control table (pitch and tension) 1 soldering machine

3. 10/7/2003Thomas Schneider3 Test of tooling with prototype 4 gluing tables with vacuum and pneumatic system have been produced. One table has been used to evaluate the new gluing procedure (new glue+ pressure/vacuum adjustment) Wiring machine Gluing table

4. 10/7/2003Thomas Schneider4 Pitch: 2mm +/-0.02mm Total:1400mm +/-0.2mm (=700 steps) 2*468mm (CERN, R1) 2*796mm (CERN, R2) 6*1450mm (PNPI, R4) Combs for wiring All combs have been checked with the quality control table and are according to specifications.

5. 10/7/2003Thomas Schneider5 Check of comb pitch precision Different measurements have been done: Wired panels without bars show directly the precision of the comps => well within the specifications (+/-0.05mm) Wired panels with glued bars gave less good results due to friction on the bars (1mm thicker panel material) 2.05 600 1.95

6. 10/7/2003Thomas Schneider6 Quality control table Tension Measurement Control software has been improved by Guiseppe Pirozzi. Final tuning of phase shift for 12 channels remains to be done. Quality control table for PNPI with pitch and tension measurement will be commissioned the next days.

7. 10/7/2003Thomas Schneider7 Soldering table The 2 soldering units are installed on the mechanic tables. Software under development. First soldering test done Commissioning will be done in PNPI after the transport

8. 10/7/2003Thomas Schneider8 Tooling for PNPI Most of the tools have been tested and adjusted during the prototype construction. Now PNPI people prepare the transport to Gadchina. The shipping of the complete PNPI tooling is scheduled for end of July/ beginning of August.

9. 10/7/2003Thomas Schneider9 M2R2 Prototype M2R2 prototype has been done in July with final tooling and material:-2 gaps single pad RO -2 gaps double pad RO

10. 10/7/2003Thomas Schneider10 M2R2 Prototype For the new M2R2 prototype gas leak rate measurements have been done systematically. New gluing procedure (including the new viscous glue Adekit 140A) provides excellent gas tightness well within the leak rate specifications (2mbar/h) : -less than 1mbar/h

11. 10/7/2003Thomas Schneider11 Plans towards the PRR Design for the M3R1 region is ready Sensitive area: 332mm*272.8mm Panel size: 414mm*355mm Corner pieces for gas insert included O-ring closing Combined AW/CP read out

12. 10/7/2003Thomas Schneider12 Plans towards the PRR Final decisions for all open design : issues of the EDR are now available : Aligned panels Components (capacitors and resistors) in the gas volume (no problems in Casaccia test) =>no more HV connectors Double cathode readout R1 Single cathode readout R2

13. 10/7/2003Thomas Schneider13 Plans towards the PRR PCB production for M3R1 will start from next week on. (10% in CERN workshop and 90% by Cistelaer in Italy) Foreseen is to have mid of August enough material in hands (10%) to build the first pre-production chamber. This chamber will be tested in the September test beam. In September a foam panel test production for the inner region in foreseen. Plan is to have 3 chambers ready for the PRR in October.
