1. 26.09.2005TRD Workshop RomaniaClemens Adler Heidelberg ROC Status Material procurement, Chamber Status TRD workshop Cheile Grandistei, Romania, 26.9.2005

2. 26.09.2005TRD Workshop RomaniaClemens Adler L0 Chambers Pad planes, back panels delivered 2xL0C0 4xL0C1 Radiators from Münster Front profiles: Use L6 profiles L-profiles: use L1C1 and/or cut L5/6C1 2 L0C0 chambers finished (not tested yet) 2 L0C1 chambers finished 2 under construction (no tested yet).

3. 26.09.2005TRD Workshop RomaniaClemens Adler ROC status at Hd 22 Chambers in total Production delays: –Installation of Air conditioning –Vacation –Hardener Problem –Sickness → Mid May until end of July no production in Hd (12 weeks) –3 Chambers had to be taken apart (Anode connection problems) → only 6 Chambers built over summer (4 during last 6 weeks)

4. 26.09.2005TRD Workshop RomaniaClemens Adler Heidelberg is also using “P-caps” now (Thanks to Andrej Radu for the caps!!!)

5. 26.09.2005TRD Workshop RomaniaClemens Adler Problems Anode wire breaking: so far all occurences were attributed to moving of anode contact strip. (reliable strategy defined now). Winding machine (rare occurences): –Not stopping at end of winding –Wire breaking (Anode)

6. 26.09.2005TRD Workshop RomaniaClemens Adler Testing/Performance Gain uniformity: <±10% Leak rate: 0.5-1 mbar*l/h Dark currents: 0-10 nA (mostly 0-2nA) –After gluing panel, dark currents are high for some days.

7. 26.09.2005TRD Workshop RomaniaClemens Adler Plans During assembly of first SM: little chamber building manpower. Continue production if time allows.

8. 26.09.2005TRD Workshop RomaniaClemens Adler L-profiles L-profile bending due to torsion of raw Wacosit profiles. Possibilities: Different Material –Polyester/ Polyvinyl: Chilo will try to organize aging test. Old material (Epoxy based) and sort out what can be used (i.e. price increase)

9. 26.09.2005TRD Workshop RomaniaClemens Adler L-profile production status Currently all L-profiles (except L0) are finished (~80pc. LxC0 profiles will be replaced) New Material expected after material issue is cleared up (additional 20%). Currently machine/manpower is used for SM production (until end of October). New Profiles not before Next year.

10. 26.09.2005TRD Workshop RomaniaClemens Adler Front profiles All profiles (60% TRD) finished. New profiles next year (additional 20% of profiles will be ordered)

11. 26.09.2005TRD Workshop RomaniaClemens Adler Back Panels Modification of L6C1 panels to L5C1 –FACC successful –price is half of new panel

12. 26.09.2005TRD Workshop RomaniaClemens Adler Conclusions Large delays during the last ½ year. Maximum production rate: 1 ch./week, realistic: 0.5 ch./week Chambers at Hd within defined limits, no major problems seen. L-profile material strategy: will be defined soon.
