1. Mike AlbrowSept 8 th 2005Test Beam for FP420 Vacuum Chambers/Detectors 1 Things we need to test (and why) How we could, together with BTeV people, detectors, DAQ The Fermilab test beam Organization, time scale, needs

2. Mike AlbrowSept 8 th 2005Test Beam for FP420 Vacuum Chambers/Detectors 2 FP420 = Forward Protons 420m downstream of CMS & ATLAS Physics is p H/WW/ZZ p Measure p’s with very high precision within 3 mm of beam  mass and quantum numbers of central state. We are talking ~ 5 microns on track over 10m, and 10 ps timing Challenges include (detectors ~ 6mm x 24 mm):  Tracker, perhaps 10 layers per station, 3 stations, 3D silicon (edgeless, 10um res., fast, rad hard).... Hawaii/SLAC + Brunel  TOF counter, quartz fiber Cerenkov + MCP-PMTs  Vacuum mechanics: Detectors in secondary vacuum, separated from 1ry by RF shield Space constraints, between beam pipes, not roman pots High precision movement (microns), reproducibility, fail-safe.

3. Mike AlbrowSept 8 th 2005Test Beam for FP420 Vacuum Chambers/Detectors 3 We have LOI to LHCC for R&D project (combined CMS/TOTEM & ATLAS) Unofficially (so far) supportive Plan: R&D now  summer/fall 2006. Make choices among options, design arms. Go to CMS & ATLAS to propose that it be an upgrade (not separate project) Hope for installation late 2008/2009 Proposed (Fermilab) test beam scenario: Integrate with the BTeV/CMS tracker in place, with its readout etc Mount each (of 2) prototype vacuum chambers, with (rough) vacuum, motions Microstation (Helsinki) and Hamburg Pipe (Louvain) with a BTeV/cms tracker layer installed and R/O... tests motion, reproducibilty and finds problems to solve with mechanics, vacuum etc. Hopefully will also have some 3D Si detectors to put in beam (with BTeV R/O) (More) hopefully could have 2 S-TOF counters to test with MCP-PMT R/O ---- premature to discuss that at this meeting (?)

Erik Ramberg in charge Up to 120 GeV protons Up to 200K/spill (more than enough!) over ~ 5 mm x 5 mm Beam diagnostics: 3 MWPC profile monitors 4 layers x-y Silicon strip detectors Cerenkovs (but we don’t care about that) (can be read out into each event) BEAM MT6-B... another area behind http://www-ppd.fnal.gov/MTBF-w/ BTeV pixel & CMS pixel current users of area A

6. Mike AlbrowSept 8 th 2005Test Beam for FP420 Vacuum Chambers/Detectors 6 If you are interested in using the Fermilab Meson Test Beam Facility, the first step is to request beamtime using the form below. Fermilab will then review this user request through a test beam review committee, which will approve or reject the request. Requests will be rejected if the request can't be met by the facility, due to capability or schedule. Approved requests will be asked to make a more detailed plan resulting in a Memorandum of Understanding between the user and the laboratory. A lengthy and a short example are given below. The test beam user will then obtain a test beam experiment number associated with their request. Each approved test beam experiment must obtain a readiness clearance before actually taking beam. This readiness clearance is obtained from the Particle Physics Division's Fixed Target ES&H Committee, which has subcommittees to review electrical and gas safety. The makeup of the committee is given in a link below. Their requirements are outlined in documents that can be obtained below. Users will have to obtain a Fermilab User ID and pass a Radiation Worker class before using the test beam. Each experimenter must read the FNAL Procedures for Experimenters manual. To access the beamline during run conditions, a user also requires Controlled Access training. The various information needed for each of these steps is gathered here: For the record, from the Test Beam web site:... but maybe we can be just considered part of CMS pixels??

7. Mike AlbrowSept 8 th 2005Test Beam for FP420 Vacuum Chambers/Detectors 7 These are the people currently on mailing list and what I think they are doing. Organization, schedules etc Please tell me corrections, additions etc. We aim to make FP420 part of CMS (and ATLAS), and we hope those not formally involved in FP420 (yet) will help to make it happen.... and some of you are probably very interested in 3D Si tests.)

8. Mike AlbrowSept 8 th 2005Test Beam for FP420 Vacuum Chambers/Detectors 8 What new resources do we need? I don’t know. Need help. Plan to ask PPD for R&D project funds (time scale should be 1-2 weeks) Need to make MOU Aim to be ready around May for beam tests of uStation and Pipe prototypes incorporating a BTev detector. Schedule for 3D Si (at least 3 layers) and STOF (2 counters) not yet clear, but hopefully similar.  What (new) do we need from Fermilab?
