J. Linnemann, MSU 2/12/2016 2 Alpha l First Production: 4-6 fully work; break/fix about 1/week l Second Production: Pre-production boards work ‚DMA fixes incorporated in layout ‚Learned can successfully replace CIA BGA (better than unreliable socket!) ‚new supplier for raw boards, better assembly (failures diagnosed; site visits) 11 more being built now: 5-7 arrive Sep 26; remainder Oct 5 PIO to Alpha not working (firmware)early October l Need 15 for nominal system (+7 for test stand) ‚concentrate on 1 Alpha/crate first—OK for low rate ‚Add processors to meet throughput demands as available l Beta replacement: prototype December ‘01, production Summer ‘02

J. Linnemann, MSU 2/12/2016 3 MBT workhorse I/O card l cards in hand Before install: stable SCL firmware Sept/Oct firmware all written; being debugged (good turnaround) ‚Scl_init sequence; L1, L2 busy (easier) Multi-card broadcast: need testing at FNAL 128 bit fanoutneeds testing at FNAL with Edmunds: Oct Some marginal timing being chased Results write to Global: needs to be re-integrated ‚tweaking output amplitude Monitoring functions: need to test at FNAL

J. Linnemann, MSU 2/12/2016 4 FIC: G-link receiver (all crates but muon) l FPGA code being tweaked Some vme problems remain ‚commissioning modes only; progress being made G-link data problems fixed (tested BER < E-10) ‚ Need pin reassignment for monitoring FPGA ‚Will swap for faster chip (socketed) FPGA compiler problems probably resolved Fermilab/ESE support for commissioning ‚Met last week with Saclay experts ‚ Consult on design; fixed 3 dead channels

J. Linnemann, MSU 2/12/2016 5 L2 Muon Cards l CIC (L2Mu input card) installed; inputs cabled l SLIC (L2 Mu processor card) ready to cable up Algorithms being downloaded already l SFO (fanout): all but 2 at Fermi Needed by Muon system, and test stand ‚Very useful for commissioning ‚May have other uses during running All cards work in most important modes ‚For one mode, have to hand-select cards ‚ Only need 2 working in 1:12 fanout mode ‚ Investigating why only half do, but half of 25 is plenty ‚why error rate different in Nebraska?

J. Linnemann, MSU 2/12/2016 6 Miscellaneous Interface Hardware l 16 to 128 bit mux add-on to MBT (UMd) Returns L2 trigger mask to L2HWFW Sep/Oct l L1HWFW to L2 Global (via FIC) (MSU) Optical Split: L1 trigger mask Aug/Oct ‚dummy content: fixed + event ID l Monitoring of Alphas by L1 Scalers (MSU) Passive cable formatting card Oct
7
J. Linnemann, MSU 2/12/2016 7 Commissioning At Last L1SCL-MBT-Alpha-VBD-L3 milestone met One channel “data”, real frame software, in MCH ‚Need to verify format from SAM Muon system has seen real inputs-CIC-SLIC ‚L1format needs correction ‚Scintformat OK but L2&timing interfere: errors ‚MDTformat OK ‚PDTunformatted: October? l Current tests: SCL_INIT for MBT-Alpha (for permanent MCH running) Add 2 nd channel of data (FIC-MBT-Alpha-VBD-L3) real algorithms into SLIC; timingFwd Mu already Muon: 2 nd or 3 rd input: CIC-SLIC-MBT-Alpha-VBD-L3 One event pushed through STT prototype vertical slice ‚FRC, STC, TFC: CTT roads, SMT clusters, fit

J. Linnemann, MSU 2/12/2016 8 Summary l Commissioning is underway in earnest Some real inputs—need more to do physics ‚Mu, cal, ctt, cps is probable order Most hardware in hand ‚Remaining alphas soon, I hope Final cabling in October Firmware written; commissioning it now ‚MBT, Alpha, FIC l Crucial scale-up tests in coming weeks ‚All hardware in crates ‚Multiple inputs ‚Algorithm downloads coming ‚ Muon: started last week; continue thru shutdown ‚ code running in simulator already
9
J. Linnemann, MSU 2/12/2016 9 Arrival of L2 Inputs When inputs steadily available (subset, full) l L1 Trigger Mask to Global (August, October) l Cal(September?, November?) l Muon Trigger (L2 software not tested)(June, November) Detector(August,October?) l CTT,CPS(October,November) l FPS(November,December) l COOR programming September?
10
J. Linnemann, MSU 2/12/2016 10 Online Software Plans Event data flow late Aug l Worker with filter code Sept Multi-alpha (as available)Oct/Nov ‚interrupts for speed as neededDec/Jan l Coor script downloading via TCC: Late Sept Till then, configure from hand-edited file ‚Online and in TSIM l Data Flow Monitoring testSept/Oct ‚Errorlogger to screen/S.E.S. Oct/Dec? l Global + PreprocessorOct-Nov FILTERING! (if have enough inputs…) l Verification: online vs. TSIM 1 st version running now; testing data capture Needs pretty good data to be usefulOct/Nov?
