 Better K/p separation power than TPC in LEPS.
 Detect proton by forward spectrometer.
 Measure direction of K+K- with DC.
 Reconstruct momenta of KK using missing
momentum of p(g,p)X
 Use TOP for K/p separation.
(Most of Kaons don’t emit Cerenkov light.)
 For kaons with Cerenkov light, we can measure
momenta using Cerenkov angle and mass of Kaon.
• Common tools
– Aerogel
– Photosensor
– GEM tracker
– Readout electronics
• Is TOP useful for other experiments ?
