CTPT/FPS ComponentsCTPT/FPS Components– Analog (Fermilab - DØ)
• AFE-8MCM (primarily CFTax): – 10 here, ready by 11/01, 54 more by 12/15, balance 01/30/01
• Crates/Cables on hand, installed when required• Power supplies delayed until new year (partial).

November – FPS DBs (double-wide, 3 Virtex 2.5v FPGAs) partial order
out– Xilinx/Virtex FPGAs for CTOT on order, others held until
further decision, Virtex vs. Virtex-E– Crates/Cables/PS all here by mid-November

CTTP/FPS Firmware: CFT/CPS AxialCTTP/FPS Firmware: CFT/CPS Axial
– DFEA (80) : Jamieson Olsen (Kin is gone)• Both L1/L2 firmware in good shape• 4 FPGAs find tracks in 4 Pt and report to 5-th FPGA and to Muon• Backend (5-th) FPGA does CPS cluster finding and track matching
– firmware has to be re-written, concerns on the chip size– expect functional and tested firmware in a couple of months
– CTOC (8) : Juan Lizarazo, now Ricardo Rodrigez • Both L1/L2 firmware completed and tested in testbench• Minor issues and additions will be addressed by Ricardo/Manuel
– CTQD (4) : Pavel Polozov now gone• L2CFT part completed functionally with some minor issue• Needs implementation, L2CPS, and all of this tested in the
hardware
– CTTT (1) : Jerry Blazey• Algorithm/VHDL/Functional/Implementation at ~20%• 2 out of 64 Trigger Terms done through the implementation phase• L1->L3 sender, finish all VHDL, implementation, hardware test
stand
DØ Collaboration Meeting, October 11 - 13, 2000, Fermilab Levan Babukhadia
CTTP/FPS Firmware: CPS StereoCTTP/FPS Firmware: CPS Stereo
– DFES (5) : Qichun Xu, MSU• No link to L1 TM, straight to L2 and L3, thus has time!• Main issue is cluster finding in the large number (~500) of CPS
stereo strips in a sector but having time may save the day...• New MSU student Qichun Xu, just started
– Made a good head-start with an overall algorithms and the cluster finding algorithms in particular
• Start writing VHDL, expect functional code in about 1-2 months
– CPSS (2) : ?!• Nobody yet! Perhaps Qichun will take on this one as
well ...
DØ Collaboration Meeting, October 11 - 13, 2000, Fermilab Levan Babukhadia
CTTP/FPS Firmware: FPSCTTP/FPS Firmware: FPS
– DFEF (32) : Levan Babukhadia• Challenge: cluster finding in 144 FPS strips at the L1 rate• L1 U/V algo developed, coded, and implemented; test stand is
next– L1U and L1V each takes Xilinx/Virtex 400 FPGA (~75%, 63 MHz)
• Develop L2 priority reporting algo to take care of truncation. It is aimed at the 3rd FPGA– Transferring clusters within a DB or find clusters anew?...
– FPSS (4) : Mrinmoy Bhattacharjee• L1 algo developed, coded, and implemented w/o the L3 sender
– fits in one Xilinx/Virtex 400 FPGA (~30%, 66 MHz)• Develop L2 algorithm
– FPTT (1) : Satish Desai• L1 algo developed, coded, and implemented w/o the L3 sender
– fits in one Xilinx/Virtex 400 FPGA (~20%, 64 MHz)• Complete all L1 functionally, test stand by the end of October

CTPT/FPS Installation/Commissioning
CTPT/FPS Installation/Commissioning
•Assembling test stands for digital/VHDL testing– Hardware: 2 PCs, MBs, 2 Data Pump Boards, PS, cables,
CTPT/FPS DBs» 1 fully stuffed double-wide DB» 10 fully stuffed single-wide DBs
– Personnel: Jamieson Olsen, Brian Connolly (very short time), Ricardo Rodrigez, and a new part-time tech
– Had 1 working test stand but recently moved to DAB3/NE; will be made operational this week
– Aiming at having 2 “single board” bench-tops and 1 “multi-board” test stand (for a one sparse system test -- available now, Jamieson)
• Installing cables/crates on platform•Crates/Cables installed in MCH
DØ Collaboration Meeting, October 11 - 13, 2000, Fermilab Levan Babukhadia
– Components• Scintillator (48) complete• CAFÉ boards (175) on hand• Completing ADC (~12) board layout, ordering parts• Vertex board, FPGA 75% complete, layout commencing• Procuring signal cables (~60) soon• Crate/PS on hand
– Installation/Commissioning• Installed scintillator (4/00) • Cabling awaits FPS, commissioning thereafter
– Software/Firmware• Working on embedded software• Download currently underway• Database under development
– Schedule (on time)• Electronics installed, February 1; Lum Monitoring March 1• And/Or terms, March-April

DØ Collaboration Meeting, October 11 - 13, 2000, Fermilab Levan Babukhadia
– Timing signal generation and distribution• Some work has been done and some tests have been made• Initial implementation will probably cover just the CC racks
– L2/L3 readout complete (by November)• Uses much of the same equipment as the readout from the TF• All circuit boards exist and initial designs of all the FPGAs exist
– Analog input circuit (pick-off) boards (320) • Prototypes of this exist and some testing has been done• 1FTE month to production
– Quadrant Terms
• Circuit board (40) and FPGA design work has been started• No prototypes exist yet• Will not be pushed in the immediate future
– Schedule (late but well before 3/01)• Inactive until TF complete 11/00. Resume within a month• Start with analog pick-offs

Near Term Commissioning Goals– Mid-August
• Stable operation of one (sparse) L1MU trigger crate and the L1MU MTM crate– still using preproduction cards
– Early October• Add L1CTPT MTM crate to the above
– Mid-October• Begin commissioning production of L1MU crates and cards
Longer Term Commissioning Goals– Begin full crate testing in late Dec or early Jan
• Two octant triggering until then• MCEN cards ~2 months behind above• Temporary power supplies for full crate tests

– L3 readout• Finish up making readout to L3 available for normal use (by 1/11)
– Master Clock synchronization with the Tevatron beam• This work now starting
– Operational permit• Need to install 5 fuse blocks and write the documentation
– L1 Specific Trigger Fired Mask to L2• Needed to make the Pseudo-Terms work• Deferred until some progress on getting L1 Cal Trigger running
again
– Firmware• Completion of pseudo-terms• Commissioning run-control
– Personnel• Major loss of two engineers. Replacement uncertain
