1. Stave -1 status and other reports Stave Loading Meeting, November 8 th 2011 G. Barbier, F. Cadoux, A. Clark, D. Ferrère, C. Husi, G. Iacobucci, A. La Rosa, J. Mesa, G. Pelleriti, M. Weber

2. Stave -1 about to be produced 1. October 6 th : Gluing of Genova flex onto stave 2. October 10 th : Gluing of Bonn flex onto the other side 3. October 14 th : Electrical probe of the flex after gluing 4. October 18 th : Wing folding of both flexes + Electrical test for line integrities 5.November 1 st : Middle support gluing 6.Now: Trying to optimize the intermediate support mechanism for wire bonding 7. Loading of <8 digital modules on Bonn flex side and 1 digital for Genova 8.Wing attachment 9.Ready for wire bonding 10.Stave-1 ready for delivery at CERN for system test and readout NB: Step 7. will start as soon as the last module (with a different module flex orientation) is received et tested! Expected soon from Genova Wire bonding jig to reference the handling frame is made by University of Bern 2 Loading to happen with jig v-1

3. Stave -1 – Cradle for Wire bonding 3 Jigs designed and fabricated by University of Bern It is expected minor modifications for stave 0 Tooling was sent since October 25 th from Bern and lost by TNT (expected soon now!)

4. First 2-chip Digital modules: 9 in total 2 single-chip module flexes glued and wire bonded to the bare modules Adapter card to interface USBPix and module flexes Test performed FE by FE (FE address is 7 for both chips) Power provided via flat-ribbon-cable from USBPix Test setup with USBPix – Module reception tests Thanks to Alessandro & Yosuke 4 Special thanks to Fabian and Claudia for module delivery

5. NB: Another module is expected soon from Genova with a different module flex orientation Threshold scan (threshold and noise measurements) using standard configuration (FEs untuned) 2-chip digital modules tested so far – Module reception tests Thanks to Alessandro & Yosuke 5

6. Z=0 Stave-1 layout Bonn flex sideGenova flex side 16 15 13 12 9 8 7 5 4 3 1 FE id – Functional flex lines 3 4 NB: It is proposed to mount 9 digital modules and 7 dummy modules (si-wafers) Genova flex need a “special” module flex type 6

7. Few Pictures of raw stave-1 Stave could not fit into the handling frame  Larger openings of one of the supports were made Middle ring support also misaligned  correction was made on the central support of the handling frame Central support glued after modification 7

8. Other operation on stave -1 While waiting for the loading to happen: -Learning how to compensate the stave with intermediate support for operation like loading and especially wire bonding - Yesterday a baby SCT detector was attached to the face plate for trying two type of supports for wire bonding - When the wire bonding cradle will be received this will be tested by the operator with the two types of support. The simpler the better and this will have to be tested in real condition by doing pull test. 8

9. Connecting PP0 on Genova flex side Comments: -1 st connector where DCS is was removed since it clashed with the end-support - PP0 connector access is limited once the stave is fixed on the handling frame 9

10. List of bare full length staves received at UniGe ID @ UniGeOriginWhat for?Comment W-01WuppertalThermal testsNow dismounted at UniGe W-02WuppertalThermal tests with Ceramic heatersWaiting for loading W-03WuppertalThermo-mechanicalShipped to Milano C-01CERNStave-1Waiting for loading NB: All the staves got the middle support glued at UniGe We request that the middle support gluing operation is done asap at Wuppertal since we have to crosscheck that it fits to the handling frame fixation points W-02 – 1 defect W-03– 3 defects 10

11. Big thanks to Gerard!!! End-block clash – Stave design to be revisited Clash found for integration around beam pipe Current design is clashing Older end-block design was ok! 11
