1. 1 UA9 September 2010 test beam Si telescope hardware status Mark Raymond – 3/9/10

2. 2 XY plane XY planes XY plane d1 UV plane d4 5 planes altogether (10 silicon strip sensors) each plane provides 2 co-ordinates: XY or UV UV plane = XY plane rotated through 45 0 (resolves ambiguities for multiple hits / trigger) d1, d4 as large as possible – maybe ~ 7 m? d2, d3 as small as possible – d2 depends on goniometer layout unless use same table for gonio and telescope planes? table height: surface must be nominally 25 cm below beam height – who will look after? (note: tables for 138 June test were ~ 3 cm too high) crystal position September test beam telescope layout in128 area d2 d3 beam trigger scintillators 25 cm upstream downstream

3. 3 XY plane UV plane sensor planes visible (no window yet) crossover area 4 x 4 cm 2 25 cm +/- ~ 4cm

4. 4 inside the box after optical hybrids installed finished analogue opto-hybrids fibres

5. 5 XY plane XY planes XY plane d1 UV plane d4 cabling, power d2 d3 beam trigger scintillators 30 analogue readout fibres 5 digital control fibres (clock & trigger) I2C hub one I2C bus (electrical cable, opto-isolated) to/from counting room 6 readout fibres per plane => 30 total 1 control fibre per plane = 5 total 1 electrical cable to I2C hub in beam area electrical fanout to each plane will need some coax cables for trigger,…. will need 2 mains sockets per plane (LV power, HV supply) should aim for one multi-socket extension cable per plane (5 total) note: the integrity of these analogue fibres is crucial to the performance of the telescope (the CMS readout system was designed for a one-off, careful installation)

6. 6 summary & plans we will provide a total of 5 XY planes for the September test (10 Si planes total) 2 upstream XY, 2 downstream XY, 1 downstream UV Geoff will bring hardware to CERN Monday 13 th Oz (Osman Zorba) and Mark (Raymond) will check out hardware in 904 (Prevessin lab) Tuesday/Weds 14 th /15 th => available to help with/advise on any cabling installation hardware to beam area Thursday 16 th – telescope commissioning begins => would like final version of triggering system there at beginning if possible table height is only other outstanding issue (I can think of at the moment)

CR-RC front end amplifier 192 cell deep pipeline (allows up to 4  sec latency + locations to buffer data awaiting readout) peak/deconvolution pipeline readout modes peak mode -> 1 sample -> normal CR-RC pulse shape deconvolution -> 3 consecutive samples combined to give single bunch crossing resolution noise 270 + 38 e/pF (peak) 430 + 61 e/pF (deconvolution) note: only discrete 25nsec samples of above shapes are available in asynch. test beam choose timing to get close to top of peak mode pulse shape

10. 10 APV readout FED readout analog opto-link digital header 128 analogue samples APV O/P Frame 20 Ms/s readout -> 7  s no zero-suppression (sparsification) on detector pedestal, CM subtraction and zero suppression on FED raw data also available for setup, performance monitoring and fault diagnosis can read out raw data at low rate – VME - < 1 kHz can read out sparsified data faster – VME ~ 10 kHz (to be verified – some uncertainty here) Slink faster – 100 kHz – but needs incorporation (and customized use) of other CMS components (probably not possible this year) VME ~ 10 MB/s Slink to CMS DAQ trigger APV provides a timeslice of information from all 128 input channels following external trigger (trigger must be timed-in correctly)

11. 11 opto-electric conversion 10 bit 40 MHz digitization pedestal and CM subtraction hit finding (sparsification) formatting and transmission of data up to higher DAQ level check of APV synchronization all tracker synchronous, so all pipeline addresses of all APVs should be the same FED checks received APV pipe address matches with expected value (APV logic emulated at trigger level) off-detector FED functionality 9U VME
