  15. Risk Management • APS Sensors depending on Strasbourg pace of development • Early prototypes, involved in testing and design • Kinematic mount, low mass ladder, alignment challenging • Solve problem in the R+D phase • SSD is essential • Involved in upgrade and running of SSD, design redundancy into IST HFT CD0 Review, February 25 and 26, 2008

  16. Performance Requirements • Thickness of beam pipe + first Pixel layer < 0.5% radiation length • Pixel integration time < 200 s • Read-out compatible with DAQ 1000 • Internal alignment and stability better than 20 m for Pixel and better than 300 m for IST • Detector hit efficiency of Pixel > 95% HFT CD0 Review, February 25 and 26, 2008
