This wiki will gradually feature more details on building as well as operating the detectors.

For a general overview please refer to the main readme.
For scientific background on the physics of the diode sensors and how it works, please have a look at the corresponding paper.

Please post your own builds online and ping me such that I can add them to the Gallery! 😀

Project introduction talk at RC3, December 2020:

youtube english, youtube german translation, CCC media server with all versions, PDF slides

Wiki Overview

• Hardware/Electronics

  • 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

  • Energy Spectra particle energy spectra and reference energy calibration
  • Oscilloscope Measurements great for checking if the detector works well
  • Software different kinds of freely available recording, analysing and simulation software

• Supplementary material (mostly related to the paper)

  • Diode Characterisation (C-V measurements revealing physical properties of the diodes)
  • Pixel Detectors (comparison of the diodes with pixel detectors from CERN)

• Workshops

  • Science Days Digital 2020 (Online-Workshop, in German)
  • Gathering of Open Science Hardware 2018 in Shenzhen China, workshop documentation
  • S'Cool LAB Summer Camp 2018 at CERN, poster presentation, page 3
  • Student Summer School of Barcelona Technoweek 2017, CERN news
  • S'Cool LAB Summer Camp 2017 at CERN, poster presentation
