Future Plans

Most probably on Thursday (October 27 2022) 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

On Wednesday (November/2/2022) will be a accelerator maintenance day. We will have an access to the Hall and can release the 3x3 SciGlass prototype (with PMTs) and start SiPM test preparation. Our next step is beam test of SciGlasses with SiPMs in the HallD.
