  1. Geometry of WLS bar + Fiber EJ-280 WLS Plastics( ELJEN technology) ( Similar to BC-482 from St. Gobain) Coupled to SiPM Emission spectrum was implemented.

  2. Optical Fiber (from Kuraray)

  3. Simulation result • Geometry( Bar+Fiber+SipM) • implemented. • ‘Wavelength shift’ process was on. • But it didn’t seem working. • ( expected the emission spectra of • WLS) • 3. Need investigations. (nm) Photon wavelength spectrum at SiPM

  4. Position by Time difference Continuous X-tal. TOP : Anger Logic (Energy weighted Position) Bottom: Using time difference. Pick-up the max. E TL. (T1-T2)*(1.0mm/0.01ps)/2 mm

  5. Pixelated X-tal Beam X = 0.5mm Beam X = 4.0mm mm mm TOP : Anger logic Bottom : Time difference 0mm 4.25mm

  6. Plan • Abstracts for IEEE • pixelated X-tal configuration. • continuous X-tal configuration.
