Fast Timing studies at Fermilab : Test beam plansnotes from meeting April 15th 2009
MTest May Wed 27th – Tue June 2nd, 12 hours/day, probably 10pm – 10am,Priority is to test Cerenkov detectors, using custom fast electronics. Keep it simple!
Want to test several devices, in order of priority or task:2 Photek tubes in line in beam with 0,2,4,6 mm extra quartz radiatorQ-bar with 2 Photek tubes, one each end. Perpendicular to beam (and x, θ scans)Q-blocks with SiPMs in line (Anatoly)GASTOFs 2 in-line, sent by Louvain. (Same DAQ, just exchange cables)2 Photonis 48 x 48mm tubes with ganged together channels, in line (+ extra Q if wanted)Iff the latter shows good resolution, would like to install them in QUARTZTOF(cones). ===============================The above is our plan.Additional tests with QUARTIC (8-bar design) and different electronics (A.Brandt)only if they are fully independent, on back table, and understand we are prime user.I will discuss this next week at UTA (Mike)

MTest May 27-June 2
All 120 GeV/c protons, intensity ~ 10K-20K per 4 sec spill, 1/minute.Small trigger scint counter ~ 2mm x 2mm 2PMTs in Dark Box. [AR]Scan to find beam center.2nd large trigger counter ~ 4cm x 4cm in line, in COINC for trigger Halo-veto counter with round hole diam ~ 5mm to reject showers. [AR]“Standard” reference fast detector, in beam & always read out PHOTEK 240 (40mm diam)These on front table, see plan later.Scanning table: x,y,θ … mount in moveable base, program it
Trigger logic & DAQ shown on next slide [ER]Very fast digital scope Set-up & waveform recording (if wanted)

Notes on detectors:
1 large (40mm diam, 2 MCPs) PHOTEK in beam center, maybe add Q. Keep fixed as Ref.
2 Photek tubes in line without & with Q-disks on window (grease? removal?) Dark Box [ER]
Q-bar: Fused silica bar 6mm x 6mm x 90mm, Photek 3μm pore 10mm Φ each end. (Beam ┴ to bar, scan along, rotate…) [being made, Lindenmeyer] Light tight, but in dark box for RF and convenience of cables etc. [MA]
Q-blocks + SiPMs in line [AR]
GASTOF: 2 devices with (1-channel) Photek PMTs [exist, from Louvain] Mounted in line on plate, too big for dark box, mount on 2nd table (assuming no QUARTICs there)
< AEROGEL ? blocks ~ 2cm long, mirror Photeks. (Not yet made) > maybe
Pair of Photonis 64-pad 48x48mm2 tubes in line (+Q plate?) to test integrated readout.
< QUARTZTOF (Cones) IFF Integrated Photonis test looks good, be prepared to put on Cone radiators (2nd separate dark box). > maybe.
