Detector Equipment
- Stack A: 14 clear sheets of scintillator around 2.86 mm thick, with mylar foil for optical isolation, in C-section stack holder and coupled to single Rev. B DDC232 board.
- Stack B: 11 clear sheets and 3 white painted sheets of scintillator with mylar foil for optical isolation (clear sheets), in C-section stack holder and coupled to single Rev. B DDC232 board.
- DAQ using USB104 A7 FPGA and Raspberry Pi (running web GUI).
