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…

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 …

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…

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…

Hello,
i am currently in the process of building two of the detectors. The PCBs just arrived and i have noticed that the SiPM PCB does not have a reflective surface around the point where the SiPM i…

Hi there,
I have been wondering about the actual efficiency of detector for measuring a single muon, since I could not find any numbers on that. Has anyone performed such a measurement or are there…
