- Use CLAS12 PCAL scintillators (4.5cmx2cmx1cm) with fiber readout to make a mini-hodoscope to find the beam position under the tagger.
- Hammamatsu H8711 Multi-anode PMT borrowed from Hall B for the readout from the fibers.
- The device is inside a "dark box" made of Rohacell.
- The hodoscope will be positioned under the tagger in Hall B, and the PMT output cables will go to discriminators then to a scaler module.
