The Fermilab Test Beam Facility • World Class Facility • The only operating U. S. HEP Test Beam • Detector R&D focus • Since 2005: § § Experiments Collaborators Countries 32 experiments 464 collaborators 108 institutions 24 countries 2006 TIPP 2011 Institutions 2007 http: //www-ppd. fnal. gov/FTBF/ 2008 2009 2010 2

Beam Delivery MTest Main Injector P 3 ne P 2 ine L 1 P Tevatron TIPP 2011 Linac 8 Ge. V Line Li MCenter Booster SY 120 Line Neutrino Line • Booster captures protons into 84 bunches (1 batch) and accelerates them to 8 Ge. V • • Bunches are 19 nsec long • • Full batch is 2 E 11 protons • In Switchyard Septa Magnet splits beam to Mesonline (and Neutrinoline) 8 – 30 bunches are extracted to Main Injector (MI) (Partial Batch) Each batch is 0. 2 – 1. 6 μsec in length MI accelerates beam to 120 Ge. V Fraction of the beam resonantly extracted each rotation over 4. 2 sec to Switchyard http: //www-ppd. fnal. gov/FTBF/ 4

Particle Composition of Beam • • • 120 Gev Protons 2 - 66 Ge. V Pions 0. 5 – 32 Ge. V Electrons Broadband Muons If beam were smoothly extracted, 100 k. Hz or less would imply 1 particle per MI rotation would occur. Beam extraction is not smooth resulting in up to 35% double occupancy per MI rotation TIPP 2011 Beam Energy (Ge. V) Rate at Entrance to Facility (per spill) Rate at Exit of Facility (per spill) % Pions, Muons % Electrons 16 132, 000 95, 000 87% 13% 8 89, 000 65, 000 55% 4 56, 000 31% 67% 2 68, 000 28, 000 <30% >70% 1 69, 000 21, 000 <30% >70% http: //www-ppd. fnal. gov/FTBF/ 5

Tertiary Beam Details Plot of Fit Momentum vs. TOF; Shows: Separation of Species and Available Momenta • 60% pions, • 40% protons, • very few electrons, kaons, and deuterons. TIPP 2011 http: //www-ppd. fnal. gov/FTBF/ 12

Tertiary Beam Details • Rates: about 200 particles / 4 sec spill (~50 Hz) • Momentum Resolution: dp = 3% § multiple scattering limited for this momentum range • Bias: § MINERv. A design goal for bias is < 2%. § So far only 5% demonstrated • WC 4 can be moved to achieve lower or higher momentum § design momentum is 200 Me. V minimum TIPP 2011 http: //www-ppd. fnal. gov/FTBF/ 13
