  1. Development of a Large Area 10 ps TOF for an EIC Detector Mickey Chiu Brookhaven National Lab

  2. Detector Possibilities MCP-PMT Si-PMT HPD APD • Many groups in the world working on 10 ps or better TOF: SLAC,FNAL,ANL,UChicago (picosecond tof group), Nagoya U (SuperBelle), FP420 (LHC) • Many different possibilities with different tradeoffs in cost, rate capability, timing capability, tiling capability….

  3. Conceptual Design • Time Zero with electron and Vertex (50 um) • Many possible benefits, not all completely worked out • Measure hadronic final state • PID for flavor identified measurements, exclusive measurements, etc • Tagging forward particles (remnant identification) • Possibly lower overall cost of detector since it can be made much more compactly • @ R=1 m, one can PID K/p to ~8 GeV • More possibilities wrt collider design (higher luminosities?)

  4. Plan • Test different detector technologies • MCP-PMT, APD’s, SiPMT’s, HPD • Collaborators: E. Kistenev, B. Morozov, S. White, C. Woody, and possibly others • Lab testing with fast laser and cosmics, later beam tests • Optimize design for eRHIC detector • Radiator design • Tiling or Scaling from few channels to a real detector • Develop Readout • Fast low noise electronics which can scale to large number of channels at reasonable cost • Collaboration with Nevis Labs • 2 year time scale • Produce a working detector prototype with best of above technology, with electronics prototype, few channels • Cost • ~$250K for materials + others, $200K more if I can hire a post-doc
