1 Forward Upgrade Meeting Closeout Richard Seto-UCR BNL Aug 18-19, 2004 Bridgeline x8383 rooms: 3-192/2-160/2-78/2-187

2 Goals for this meeting Muon trigger technology Muon trigger funding Muon trigger funding we must decide! we must decide! the NSF proposal (jan!!) the NSF proposal (jan!!) we must decide! we must decide! R and D plans and requests steps toward CDR (s) Apr 2005 ?? Next major meeting? Where are we going, and why am I in this handbasket?"

3 Attending most of the meeting In person rich, ken, astrid, vasily, matthias, wei, naohito, hideto, Shoji kohei, kazuya, John H, John L, dave K, imran, atsushi,?? On phone (for part of it) dave lee, vince, Ed Kinney, Mike L,??? RKS note – the highest priority was to reach some decisions – hence several talks were skipped

4 Muon trigger technology-Performance for triggering: 1)rejection for W in pp, heavy vector mesons in AA, open charm/bottom in pp and AA.  simulation for AA – wei timescale<1mo 2) Stability against collisions related backgrounds: decays into muons, combinatorial background from spectator fragments showering of the beampipe or material close to the beam pipe.  shielding help noise? kazuya and wei, yajun timescale<1mo  use pisa to do this – fragments – check with kazuya for fragments 3)Beam related backgrounds: hardron punch through, neutrons, decay-muons, incoming vs outgoing beam background.  background from beam – incoming -finish Scint test – run4 (wei check this)  mars to pisa Vasily< 1mo  DECISION made: one plane or more of fast device – i.e. RPC 4)Can trigger info be passed on to LL1 within one clock tick?  design – 2 beam clocks to lvl1 (fast hardware) RPC OK  measure for Cathode – timescale< 1 month 5)"Noise" rate (in absence of any physics signal) in the trigger.  Noise – RPC – measure or send Matthias– few days- Answer by next week DECISION: within 1 month Naohito/Matthias will agree on a trigger technology which will satisfy the requirements of W physics This is the primary criteria in choosing a technology/?- additional information may come from NCC for W physics RKS note – even end of Sep is late

5 Muon trigger technology-Tracking issues, integration issues Tracking Issues 1) Is it necessary to improve the pattern recognition in AA? (YES-Vince) How can this be best done? 2) muTr resolution vs splitting of a trigger signal at the front end ( ASD may fix this for cathode) This is a more difficult problem needs expertise from muon tracking person may increase cost- what is needed is probably theta Integration issues 1) How long does it take to upgrade muTr FEE; can this be done during a regular shutdown? How can the installation of new decidcated trigger counters be integrated with the running schedule?  2 shutdowns 2) How to solve integration issues for possible RPCs upstream of muTr magnet, downstream of muTr magnet or downstream of muID in gap 5?  Need to talk to Pete etc 3) Do we have a scheme in which we can combine the LL1 information for muId/muTr/RPC within the time budget for a level 1 decision? John says at first order its OK [see John’s slides~ 25 clock ticks OK, probably have 10 available since 15 are used] 4) Coordination with PHENIX muon group. There may be pretty strong oppinions on which solution is preferrable. RKS note : we will revisit these issues in a month after the technology is picked

6 costs Mu trig (to solve W trigger problem) RPC – $900K cathode readout 9K channels ~ $1M Bottom line either scheme or hybrid costs ~$1M To solve pattern rec may double this just from increase in channels NCC 1 side - $3M, Both sides $5M, incl gamma/pi0

7 upgrades-Mu trig NSF? MRI Decision: strawman for funding $1M Japan special grant DOE Nuclear Japan-Riken upgrades-NCC Later $100K $2M+ $1M+ Europe? Later$2M+ Later Japan PHENIX R&D $100K funded or promised to be requested hopes RKS note – discussion (a tough one which took most of the time) included Hideto – hence the green lin Astushi will be the point person for these funds

8 NSF proposal (more from Ken who will run the show) Request ~$1M for mu trig (DECISION) Will go through UIUC(matthias) (DECISION) participating – UIUC, UCR, ISU, Colorado, RIKEN, Kyoto, Bejing, others? ~$1-200K per institution for now- people start looking for matching fund (30%- no more, no less) ISU – trigger RPC (where? UIUC, Kyoto, Bejing) ?? John Hill- editor- 15 pages w/o budget (DECISION)

16 Muon Trigger Cost Estimate: Draft -1, November 30th Assumptions: 0) $100k from regular UIUC budget for RPC related R&D and prototypes a) Upstream tracker (UT) is dedicated RPC upstream of muTr station I: 2m^2 b) Downstream tracker (DT) is dedicated RPC in gap 5: 110m^2 c) two gaps in each station need 20% spare modules ==> need 538m^2 at $162k d) $300/m^2 for RPC ($110/m^2 is the Belle price) This includes the two cathodes (azimuthal and tile) and frontend needed to form azimuthal tiles. e) Granularity: 360 azimuthal strips in each station 10x10cm^2 tiles upstream 30x30cm^2 tiles downstream -> 4184 channels + 10% spares f) Cost for Frontend electronics $100/channel + 30% overhead (obviously this is a generic number; we need to develop new amplifier-discriminators including some logic.OR. for the azimuthal strips and should re-use existing FEMs -> TOF?!). ==> $599k g) Need two muId-type LL1 to collect RPC signals on one side and one additional one to correlate muID.LL1 and RPC.LL1 -> 6+4 spares. Assume: $10k/board including overhead and manpower for modest modifiations. h) online and off-line software - including the FPGA algorithms - will be written by postdocs and graduates students supported by the regular grants. RPC costs

17 RPC costs cont With this: -> R&D, prototypes $100k (from regular NSF grant) ======================================================= -> Mechanics for integration: $50k (from NSF-MRI... (labor from PHENIX operations) -> Gas System $50k (labor from PHENIX operations) -> RPC hardware $162k -> RPC FEMs $599k -> LL1 $100k...) ======= $961k -> get NSF grant for undergraduate institutions -$100k ======= $861k to NSF MRI

18 costs cathode readout 9K channels ~ $1M Bottom line either scheme or hybrid costs ~$1M To solve pattern rec may double this just from increase in channels
