We propose a novel approach for observing cosmic rays at ultra-high energy (>1018~eV) by repurposing the existing network of smartphones as a ground detector array. Extensive air showers generated by cosmic rays produce muons and high-energy photons, which can be detected by the CMOS sensors of smartphone cameras. The small size and low efficiency of each sensor is compensated by the large number of active phones. We show that if user adoption targets are met, such a network will have significant observing power at the highest energies.
Yeah, not downloading this, but it does sound cool.Automatically Collected Information
In addition, the Application may collect certain information automatically, including, but not limited to, the type of mobile device you use, your mobile devices unique device ID, the IP address of your mobile device, your mobile operating system
The CRAYFIS Initiative is a global project that aims to create the world's largest network of mobile phones to study cosmic rays. The purpose of this initiative is to utilize the power of smartphones to collect data on cosmic rays and contribute to scientific research.
The CRAYFIS app runs in the background of your smartphone and uses your device's camera to detect cosmic rays. When a cosmic ray hits your phone's camera, it creates a small flash of light which is captured by the app. This data is then sent to a central server for analysis.
Yes, it is completely safe to join the CRAYFIS Initiative. The app only uses your device's camera and does not collect any personal information. Additionally, the amount of radiation emitted by cosmic rays is very low and is not harmful to humans.
To join the CRAYFIS Initiative, you can download the CRAYFIS app from the App Store or Google Play Store. Once the app is installed, simply open it and follow the instructions to join the network. You can also visit the official website to learn more and join the initiative.
By joining the CRAYFIS Initiative, you will become part of a global network of citizen scientists contributing to cutting-edge research on cosmic rays. You will also have the opportunity to learn more about astrophysics and participate in various activities and challenges. Additionally, there may be opportunities for your data to be included in scientific publications and presentations.
