An EMC for Super B

An EMC for Super B. With the likely time structure of SuperB, backgrounds and radiation damage to the EMC should be reduced from those at a 10 36 conventional collider In the endcap region, at least, there will be multi-Bhabhas within the decay/integration time of the CsI(Tl)

Presentation Transcript

  1. An EMC for SuperB • With the likely time structure of SuperB, backgrounds and radiation damage to the EMC should be reduced from those at a 1036 conventional collider • In the endcap region, at least, there will be multi-Bhabhas within the decay/integration time of the CsI(Tl) • A faster scintillator with a smaller Molière radius may be needed • We have an excellent candidate in LSO or LYSO, which is under active study by Ren-Yuan Zhu at Caltech • We are also developing a liquid Xe scintillation counter,although this is more difficult to integrate into an existing detector and is probably irrelevant to SuperB David Hitlin Frascati SuperB Workshop March 16/17, 2006

  2. Scintillating Crystals for HEP David Hitlin Frascati SuperB Workshop March 16/17, 2006 a. at peak of emission; b. up/low row: slow/fast component; c. measured with bi-alkali PMT

  3. Comparison of CsI(Tl) and LSO spectra and readout David Hitlin Frascati SuperB Workshop March 16/17, 2006
