• Single MPPC (2 generations), the 1st generation (Vop ~ 70V) and 3rd generation (Vop~ 57V)
• MPPC array (4×4= 16 channels)

Only soldering option is available for single MPPC. MPPC array is going with a dedicated PCB The readout circuit will be provided

• Two types of scintillator, each teams is with four scintillator bar. The size is important to estimate the cosmic muon rate
• Consider the arrangement with wavelength shifting fiber (WLS)
• Consider the light tightening

• Need to cut (length should be estimated)
• Need to polish
• Need to consider how coupling with single/array MPPC
