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 email 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 issuesTracking Issues1) 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 issues1) 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 shutdowns2) 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

RPC – $900K cathode readout

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

RPC costs contWith 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

19

rest is notes

20

2004 (now) 2005 long pp 2006 (prototype)(500) 2007 (prototype) 2008 (fully ready)(500 GeV) must be pads? – then it needs new

chambers 2009(500 GeV)

21

add kyoto, riken, Bejing ISU trigger rpc’s where? (UIUC/Kyoto?) document – John 15 pages w/o budget add naohito, atsushi

22

Things that need to be answered to choose a technology to do W physics simulation for AA – wei <1mo shielding help noise? kazuya

and wei, yajun <1mo use pisa to do this

background from beam – incoming -finish Scint test – run4 (wei check this)

mars to pisa < 1mo DECISION made: one plane or

more fast device – i.e. RPC design – 2 beam clocks to lvl1

(fast hardware) RPC OK, measure for Cathode - 1 month

Noise – RPC – measure or send email – few days

Things that need to be answered to fix the pattern recognition problem This is a more difficult

problem needs expertise from muon

tracking person may increase cost

tracking yes, needs some work

ASD may fix this for cathode 2 shutdowns Integration issues

installation of RPC Time budget in LL1

John says at first order its OK

mu trig- plans to reach decision on technology
