Hello! It has been really fun to work on this project. However, we are running into some issues. When we attach the wrapped scintillator to the board, we do not get any meaningful signal as we expecte…

Thank you very much for this wonderful project. However, I encountered a problem while running it. After executing the command `./sipm_scintillator_app test.mac`, I received three output files: `time.…

I finished the mechanical design of the scintillator assembly and AFE
The setup consists of 4 PCBs:
- main AFE board with CPU, connector, LDOs, an amplifier for 1 SIPM
- auxillary AFE board with th…

Hi,
I have built 3 detectors thus far and none of them seem to work. They all are giving off ~29.6 V but none are not giving off any counts at any normal rate.
90% of the time there are zero count…

Hi Spencer,
SiPM (MICROFC-60035-SMT-TR) specified in the parts list is difficult to obtain and has a high price in a single order. That's why I'm looking for similar cheap SiPMs.
I found a 3x3mm…

Hey i just finished building two of the detectors. Such a great project!
Sadly only one works. The other one shows no detections at all. Does anyone have an idea what could be the problem?
The main …

There appears to be a missing link to a video:
> The top side of the Main PCB is used strictly for the SiPM. We’ve made a video describing this part, that you can view here.

Dear Axani
1. How to do the calibration part?
To determine the correlation between a measured ADC value from the peak detector circuit and the actual SiPM pulse amplitude, we begin with taking a s…
