Who can participate? 

Every institution or school with access to a cosmic ray experiment that is capable to carry out one of the measurements described in the Program can participate. 

Where and how do I register? 

The registration is already open. Any group wishing to participate should register through the website listed under Participate. Please note that by group we mean all students that come together in a common place and spend the day together. Only one organizer per venue should therefore register the group. The participating students are registered individually at the locations. 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. No Indico account is required for registration. Only if you want to change your registration later, it is necessary to have one. 

Do I need cosmic physics knowledge beforehand?

No. All knowledge you need you will learn during the day.  

Is there a fee to participate? 

No. The ICD is free of charge. 

Which institutes are participating? 

You can find the list of participants on the Map

Have there been International Cosmic Days before? 

Yes. The first one was in 2012, more information can be found in the archive under Media
