R&D History

• Preliminary study

  • Imaging test with IIT(2000)
    • Confirmed Cherenkov ring from Aerogel

• R&D for Belle PID upgrade

  • Proximity focusing Aerogel RICH
  • was introduced by Toru Iijima(Mar.,2001)
  • Detector design with Simulation study
    • n=1.05, 20mm thickness Aerogel
  • Cosmic ray test at IJS(Jun-Oct.,2001)
  • 1st Beam test at KEK 12 GeV PS ( Nov-Dec.,2001)
    • Confirmed principle
  • 2nd Beam test at KEK 12 GeV PS ( Nov.,2002 )
    • With improved aerogel, PMT and readout system
    •  Preliminary results will be shown
