MTest Pixel Telescope – Status Update David Christian September 11, 2007
MTest Telescope • Constructed using “BTeV pixels” • Pixel size = 50m x 400m (600m) • Oriented to provide “precision-x” or “precision-y” measurements.
Layout • Aperture ~ 3.5cm x 3.5cm • 4 – 6 stations y y Beam x x
Nomenclature • Station = 2 planes & an SLINK • Plane = 3 modules mounted on a TPG heat spreader • Module = hybrid pixel detector glued & wire-bonded to a High Density Interconnect (Kapton flex circuit) • Hybrid = pixel sensor bump bonded to 4 FPIX2.1 ASICs
DAQ Overview ROUTER SLINK Trigger/timing signals Twin-ax (sATA) Removable disk Fiber PCI Interface LINUX pc Trigger/timing signals
DAQ • SLINK communicates with 2x3x4=24 FPIX2.1 chips & with ROUTER. • Relays commands & responses • Collects data • Deserialize (digital phase follower) • Time order & construct data blocks w/extended time stamp & chip ID headers • Hierarchy of 2-way data merges
DAQ - continued • ROUTER communicates with PCI interface & SLINKs and (optionally) DUTs • 12 sATA ports, 4 RJ45 ports • Relays commands & responses • Collects data • Hierarchy of 2-way data merges (same logic as SLINK) • PCI Interface communicates with ROUTER & pc • Relays commands & responses • Uses 3 CSRs & 3 ring buffers in the pc main memory (64 MB)
Detector Status/Plan • Hybrid development complete • 11 good hybrids in hand • Balance waiting for LANL PO to VTT • Delivery Jan – May (schedule risk) • Module development • 4x HDI layout ~85% complete (FNAL) • Prototype by end of October, production Nov-Dec (on the optimistic critical path)
Detector Status/Plan continued • Plane/Station development: • TPG in hand, reinforcing about to start (FNAL) • Mechanical design underway (FNAL) • SLINK pcb layout & final design is waiting for completion of 4x HDI (Nevis) • Box/Area: • Cleanup has started • Mechanical design underway (FNAL)
DAQ Status/Plan • DAQ Hardware/Firmware (Nevis) • PCI interface ~90% complete (trigger/timing hooks not written) • Router ~70% complete (trigger/timing, implementation of merges, integration of DUT?) • SLINK • Prototype tested at ~90% level; linked to 2 modules • Design/layout waiting for 4x HDI • On the optimistic critical path
Software Status/Plan • Online software (FNAL, Syracuse?, UNM?) • Core low level routines exist & have been tested. • Need to specify online, including online/offline boundary, write & test code. • On the optimistic critical path • Offline software (Syracuse, FNAL?, UNM?) • Data unpacking • Alignment • Tracking, integration of DUT • On the optimistic critical path • Strategic decisions to be made in the next 4-6 weeks
Schedule • Focus on full telescope in ~Feb • If bump bonding is delayed (past ~Jan)… • Install 1st station + fragments as available (~Jan?)
