  1. TRD ROC Status The long and winding road to production start TRD Status meeting Münster Clemens Adler

  2. Wire frame: new design, (size opti-mized). Will be ordered by GSI. One usable frame at Hd. Glueing tables: in production Vacuum table: in production Winding machine modification next week. Crane: ->end of year Tooling TRD Status meeting Münster Clemens Adler

  3. Hecht Video measureing table Tooling cont. Harry: Feb 2003 CA: Okt 2003 • Hecht will come and fix table • No showstopper TRD Status meeting Münster Clemens Adler

  4. Padplanes: 20 L1C0 arrived Fischer Panels: 1 ready at HD 40 ready at Fischer (L1C0, L2C0, L5C1, L6C1, each 10) Material • Wacosit Frame profiles: • being machined now • Wireledges: • first set willl be machined at Hd. • Radiators: • 15 at Hd TRD Status meeting Münster Clemens Adler

  5. 1 Padplane needs remachining, 2 Padplanes were cut too short-> will be re-produced Optiprint forgot to rough soldermask surface... Holes were not machined w.r.t. right layout pattern New Optiprint offer is ~15-20% higher -> might be misunderstanding (chem. Tin,too many holes) Padplanes ->Waiting for response TRD Status meeting Münster Clemens Adler

  6. Problem: shorts due to insufficent heating of solderpaste. Solution: shorter solderpads (6mm->4mm) Apply solderpaste with stencil (well controlled quantity) Soldering equipment (dispenser solder-paste etc. is bought by IKF) Soldering TRD Status meeting Münster Clemens Adler

  7. Currently: machining of panel alu profils Start machining of front panels (next week) Start machining of side panels (next week) Padplanes soldered just in time Panels: ship just in time Vacuum table delivery: Nov, 10 ->Production Start: Nov 10 - Nov 17 Production Schedule TRD Status meeting Münster Clemens Adler

  8. Padplanes: order L2C0, L6C1,L5C1 Fischer panel: same types+LxC0 Wacosit: Wait for first finished chamber, if OK-> order 60% TRD Cables: ordered 1000 additional. Check legth, update design-> order 60% of TRD All other Material ordered/delivered Further Material planning TRD Status meeting Münster Clemens Adler

  9. H. Daues suggests: „reversible gluing“ of padplane panels. Not clear how it could be done, GSI will investigate. First Chambers will be „one way gluing“ Glueing of Panel TRD Status meeting Münster Clemens Adler

  10. At Hd: first tests until everything works/ everybody comfortable Proposal: Final test at GSI (for realistic pain level) -> to be discussed... Electronics Testing TRD Status meeting Münster Clemens Adler
