We are a team of scientists aiming to develop a low-cost, pocket-size cosmic ray detector.
This blog hosts the update of the development of the detector, that we aim to provide through crowdfunding soon.

An overview of the project can be seen in those slides : CosmicPi_GoingBeyond

and this video :


Want more details ?

A description of the first prototype, focusing on the electronics, is available in this blog post, while the hardware part with the scintillator is described in this post.

Our design is open-source, as our code that you can find on our github.

We support the Open Data Format so citizen cosmic rays experiments can share their results.

  1. Hi , how are you ?
    Congratulations for you project, I like to see education projects of technology and science using the platform open, because is the way to world better.

    1. We can absolutely talk more about this brilliant idea (and think about characterising our detector by -50 °C).

  2. Hi guys,
    I’m an undergrad studying particle physics and computer science. I have experience with particle detection (built a TOF detector and researched at PHENIX) and raspberrypi. I just wanted to know how I can help! I think this is a very exciting project and would like to lend a hand. I’ll also be traveling to South Africa in the next few weeks and wanted to ask about bringing a pixel there! Thanks!

    1. Hi Tyler, thanks for your interest. We’re still working on the development of our electronics, so it’s going to be a while before we have something you can take to South Africa. Please keep following our progress, you can either build your own when we release our full design under the Open Hardware License or purchase one fully assembled from our crowdfunding campaign. Our code is published on Github, so if you want to help with the project in the meantime please feel free to take a look and suggest improvements! Cheers,

  3. Hey guys, long time no see (for Etam Leila and Ruslan)!
    My school would love to join a project like that. How much does it cost to have one detector? And is it interesting to have 2-3 in different building?

    Looking forward to discuss it with you.

    1. Hi Fanny, nice to hear from you !
      Latest simulation show that we can expect a CosmicPi for roughly 400 CHF, though we are studying if we can lower costs (bigger production, are some parts really necessary..)
      We are still doing simulation to have an idea if there any possibility to reconstruct showers or do coincidence between 2 CosmicPis, but having several allow you to compare rate according to altitude, wall screening etc.

  4. Hi, it’s a really great project. I’m a uni student in the UK and will be running a weather balloon experiment in early 2017 to observe effects of cosmic rays on certain materials. I was wondering if these Pis will be ready by then? I would love to be able to use this to detect what our payload is being hit with while 30km up. If possible are you then able to share the data with us about that specific pis journey? Any advice would be hugely appreciated. Thanks

    1. Hi Ryan,

      Thanks for your interest! Unfortunately our first batch, which will be shipping shortly, are destined for schools all over the world who competed in the CERN Beamline for Schools competition this year. Once we’ve got them out, we’ll be thinking more about how to get our design to more people. However, one of the things we’re definitely planning to do ourselves is exactly what you describe – launch one in a high altitude balloon. Of course we’ll make the data publicly available when we do. The launch conditions aren’t looking so great for us this week, but as soon as we have a window we’ll publicise it on Twitter, Facebook and of course our blog.
