Presentation transcript:

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.

Optical Fiber (from Kuraray)

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
