New CHOD detector for the NA62 experiment at CERN
The New CHOD is a scintillation hodoscope with a pad structure featuring a total of 148 counters. The signal from each pad is read out using wavelength-shifting fibers and two or four SensL SiPMs with a sensitive area of 3 × 3 mm$^{2}$. This photodetector has 4774 pixels 35 × 35 μm$^{2}$ in size.

| Sumario: | The New CHOD is a scintillation hodoscope with a pad structure featuring a total of 148 counters. The signal from each pad is read out using wavelength-shifting fibers and two or four SensL SiPMs with a sensitive area of 3 × 3 mm$^{2}$. This photodetector has 4774 pixels 35 × 35 μm$^{2}$ in size. The key parameters (photon detection efficiency, dark current, crosstalk, and gain) were measured for 500 SiPMs. |
