17. The crate prototype

18. Design – blueprints – materials – safety Realization – The SM- crate proto has been tested at 0° angle SM crate load test @ CERN

19. Dummy strip modules

20. Additional testing phases

21. Mechanical work summary for 2007 Work in progress @ CT: – Installation of 1 universal stacking fixture and 1 compression table. – Procurement of ancillary equipment (load cells, amplifiers, etc) Work in progress @ CERN: – Load Test of the SM crate proto at 90° – Insertion test SM – Construction of the insertion plane Catania planning for 2007-8 (mechanical)

22. Catania activity electronics, offline  New lab space available for massive APD tests  Procured all the cards of the standard PHOS/EMCal electronic chain to be used for the APD test. This standard CERN set-up is almost ready (work is in progress on the software installation).  Draft for protocol for APD test established  First prototype for APD characterization as a function of the temperature is ready. Characterization of ALL 85 APD+CSP is done.  First version of track-matching ready and in CVS.
