For a short general overview please refer to the main readme.
There are two detector versions based on the same circuit board using similar components:
- Electron-Detector variant which is easier to build, use and more sensitive (more sensor volume than the Alpha-Spectro.)
- Alpha-Spectrometer variant which can measure characteristic energy spectra of alpha decays (and also count electrons)
For scientific context on the physics of the diode sensors and how it works, please have a look at the corresponding paper. It explains for example why the sensitivity to gamma radiation is rather low for both detector variants.
- Assembly Instructions - parts, tools, build instructions and troubleshooting
- Batteries - rechargeable 9 V NIMH accumulators are recommended
- Cables - connecting the signal output to a soundcard or a smartphone's/laptop's headset socket
- Diodes - different types of PIN photodiodes, blocking of radiation/light etc.
- Enclosures - chose the right kind of metal box for your DIY particle detector
- Soundcards - recommended low-cost USB soundcards, recording settings
- Troubleshooting - debugging the detector after assembly
Taking detector data, recording and analysing measurements
