CERN Test Beam Details The muon beam hit directly to the surface of the candidate PMTs. By this way we compared the abnormal event amplitudes with Hamamatsu R7525 window. We used HF quartz fiber bundle to create Cerenkov for PMT tests. We also constructed a quartz fiber calorimeter prototype to test all PMTs with showering beam.

Quartz Fiber Prototype To test the candidate HF PMTs we have built a quartz fiber calorimeter prototype. Dimensions: 20 cm x 20 cm x 45 cm Absorber: 6 mm diameter iron rods Fiber: 0.3 µm core quartz fiber with plastic clad We cleaved and shipped the fiber s from Iowa. The absorbers were purchased/machined at CERN.

Quartz Fiber Bundle We used HF Quartz Fiber Bundle to create Cerenkov light. Beam Direction Candidate PMT HF PMT

28 E907 (MIPP) MIPP (E907) proposes to measure hadronic particle production with particle identification in the Meson area using primary and secondary beams from the Main Injector MIPP has a rich physics potential with different Beam type, energy, and target material. 3 Iowa MWPC are being used for particle tracking

With laser  = 532nm (≈ 2.33 eV), the back-scattered photon has E  max = 225 GeV and the scattered electron E e min = 25 Gev; the respective angles are of the order of about 10  rad for both (in the average) eV 250 GeV ≤ 225 GeV ≥ 25 GeV ILC Polarization Measurement - By Compton back- scattering of laser polarized photons (Cross- section depends on polarization of both electron and photons) ‏ - Measurement is done by looking at the assymmetry between number of scattered photons and energies - Was successfully done at SLC - Forward detector was Quartz Fiber Calorimeter
