5. Meson Test Beam Facility  Currently the only operating high energy hadron test beam in the world (CERN accelerators are shut down)  Duty Factor = 4 sec/min 24 hr/day  120 GeV protons, ~4 – 60 GeV   (mu, e decay products, tagged by Cerenkov)  Up to 300 kHz  Almost completely booked now – June 2014  Typically 2 users; 1 primary during day, the other at night. 5 David Christian, Fermilab S&T Review - November 5-7 2013

6. From a user’s point of view  Web site has description of facilities, beam properties, and directions on how to request time.  Technical Scope of Work document.  Includes hazard analysis  TSW reviewed by PPD and AD (impact and safety)  Facility manager is primary point of contact  Facility manager manages the schedule of users  Tests are typically 1-2 weeks long  Installation, safety reviews, & training take ~1 day  Typically 2 concurrent users (primary day/night)  AD Operators alerted ahead of time to planned beam conditions; experimenters call Main Control Room to request access, change in beam, etc. 6 David Christian, Fermilab S&T Review - November 5-7 2013

7. What does a typical user use?  Floor space (some areas have overhead crane)  Electricity  Gases  Remotely controlled movable table  Patch panels w/cables to control room  Beam (of agreed type and rate)  Beam line instrumentation  SWICs, SEMs, scintillation counters  Cerenkov counters 7 David Christian, Fermilab S&T Review - November 5-7 2013

8. Example Users  CMS Forward Calorimeter for Phase-2 upgrade (HEP)  U.Iowa, Fermilab, …  LYSO Shashlik  Tracking & Particle ID detectors for e-Ion collider (NP)  BNL, Florida Tech, Stony Brook, UVa, & Yale  Mini-drift GEM  Large area planar GEM  Cerenkov detectors with large low cost VUV mirrors 8 David Christian, Fermilab S&T Review - November 5-7 2013

9. MTBF Infrastructure Improvements  Upgraded laser alignment system  Increased cooling capacity for SiPMs  New wire chamber readout system using amplifier/discriminator from CDF Central Outer Tracker (ASDQ)  Based on system developed for SeaQuest  Improved performance (with respect to 2012)  Large number of 1mm PWCs available  Improved user support Instrumentation technician(s) DAQ specialist  New larger aperture SSD tracker  D0 upgrade sensors, BTeV FSSR2 ROC, CAPTAN DAQ.  FNAL/ESE – Purdue collaboration  Ready for use in January 2014 9 David Christian, Fermilab S&T Review - November 5-7 2013

10. Improved User Support (improvements in red)  Facility Manager: Full time Engineering Physicist  Deputy Manager: 0.9 FTE Applications Physicist  Technical Coordinator: Full time lead technician + 3 FTE technicians  Instrumentation Support: 0.75 FTE Engineering Physicist + 0.5FTE on-call technician  DAQ Support: 0.4 FTE Engineering Physicist 10 David Christian, Fermilab S&T Review - November 5-7 2013

11. Being Commissioned Now  High rate tracking test area  In original test beam line upstream of rate-limiting pinhole collimator  Expect rate tunable up to ~2 GHz/cm 2  First user is CMS pixel group (Phase-1 upgrade) 11 David Christian, Fermilab S&T Review - November 5-7 2013

12. Anticipated Later in FY14  MCenter test beam area  Dedicated to large and long-term installations  First user will be LArIAT collaboration  Have moved the tertiary beam line used by MINERvA in MT6 to MCenter  Beam line work (magnet relocation, shielding enhancement) starting ~now (technicians are becoming available after shutdown)  Control room being built downstream of MT6 12 David Christian, Fermilab S&T Review - November 5-7 2013

13. Test beam facilities in/near to the Meson Detector Building 13 Existing test beam areas New test beam New control room David Christian, Fermilab S&T Review - November 5-7 2013

14. Tertiary Beam used by MINERvA 14 David Christian, Fermilab S&T Review - November 5-7 2013

15. LArIAT (Liquid Argon In A Test beam) 15  Collaboration of >50 physicists from ANL, BU, Caltech, Chicago, Cincinnati, Fermilab, Imperial College, LANL, LSU, Manchester, Michigan State, U. Minn. Duluth, Syracuse, UT Arlington, UT Austin, Univ College London, William & Mary, & Yale  Spokespeople:  Flavio Cavanna (Yale) & Jennifer Raaf (FNAL) [Phase 1]  Mike Kordosky (William & Mary) & Brian Rebel (FNAL) [Phase II] Phase I: Reuse ArgoNeuT detector with modifications to cryostat & TPC, and with light detection added. Phase II: Study in detail the interactions of moderate energy particles in a LArTPC large enough to approximately fully contain the hadronic showers. David Christian, Fermilab S&T Review - November 5-7 2013

16. Tertiary Beam Optimization 16 Tertiary beam will be configured to obtain a spectrum of charged particles closely resembling that expected in future neutrino experiments. (G4Beamline simulation) David Christian, Fermilab S&T Review - November 5-7 2013

17. New Procedures  User demand for test beam time is high and appears to be increasing.  It is likely we will have to begin turning down requests for beam time soon.  Need a transparent process for deciding test beam allocations  Since the Fermilab test beam facilities are community resources, the process should include input from outside of Fermilab.  Plans for the formation of a Test Beam Advisory Committee are being developed.  This is a Program Planning initiative.  The new committee will be drawn from Fermilab Detector R&D Advisory Group and from universities and other labs; chair will be from outside of Fermilab.  Expect to implement this plan over the next few months. 17 David Christian, Fermilab S&T Review - November 5-7 2013

18. Summary  Fermilab and CERN operate the only high energy hadron test beams in the world.  The Fermilab facility is heavily used.  Primarily by HEP Community, but also NP, Astro.  The facility has been significantly improved over the past year.  Enhanced support team  More and better instrumentation is available for users  New high rate tracking area  Facility improvements are ongoing  New test beam for long-term installations (LArIAT)  Expect to form a Test Beam Advisory Committee 18 David Christian, Fermilab S&T Review - November 5-7 2013
