Future Plans

October/27/2022 ---> Most probably on Thursday will be an access to the Hall-D. We are planning to change the HV dividers (to those with no pre-amplifier) and increase HV (from 1000 V to 1100 V) on the 3x3 prototype in order to improve the photodetection efficiency. Everything is ready to go to the Hall. Since there is no paper-based instruction for all this procedure, I'll try to make one for the future tests. https://userweb.jlab.org/~yeran/SciGlass/Towers+5mm+3mm.pdf
November/2/2022 ---> On Wednesday will be a accelerator maintenance day. We will have an access to the Hall and can release the PMT based 3x3 SciGlass prototype and start SiPM test preparation. Our next step is beam test of SciGlass with SiPMs.
November-December 2022 ---> SiPM based 3x3 SciGlass (2x2cm, 40cm long) prototype beam test in the Hall.
January 2023 ---> SiPM based 5x5 SciGlass (2x2cm, 40cm long) prototype beam test in HallD.
