For the first 50 registrants from IN2P3: No fee is required for this school for the first 50 registrants. Lodging and meals are the charge of the SOS school. Travel will be at the expense of their laboratory. For non-IN2P3 registrant or late registration (after 26 January): A number of appartements are still available. But a fee of about 400 euros is applied, which covers the stay at the site. Please contact the organizers for more information.
