You want to participate in the International Cosmic Day? Great!

This is how it works:

  • First you need a Cosmic Ray detector
    If you do not have a detector and want to join either QuarkNet for the U.S. or Netzwerk Teilchenwelt for Germany, contact the networks directly (for QuarkNet contact Mark Adams, for Germany astroteilchen(at) By joining the program of QuarkNet, you are eligible for a summer workshop. After you take a workshop, you can receive a detector for your classroom. 
  • Team up with others
    One main purpose of the ICD is to encourage collaborative work. You are supposed to work in groups and can only register as such.
  • Register

    Any group wishing to participate in ICD should register through the website listed under "Registration". Please note that by group we mean all students that come together in a common place and spend the day together. If more school groups are gathering together in a venue, this is considered one group. It is not important to distinguish the schools or institutions from which the participants come. We use the registration data to exchange important information for planning the day and to display the Google Map with all venues of the day. Only one organizer per venue should therefore register the group. The participating students are registered individually at the locations. No Indico account is required for registration. Only if you want to change your registration later, it is necessary to have one. Please note that registration is possible until November 15, 2018.

  • Plan your day
    We organize the communication between the different groups, but not the individual participants. When registered you will receive a customisable poster to announce your event and more informations about planing the day.
