How to Apply for Beamtime at TSL

How to Apply for Beam Time

In order to get your beam time scheduled at TSL irradiation facilities, please download the Beam Time Request form, fill it in, and send it to

The beam time request may refer to a single irradiation campaign or to several campaigns over a longer period. The long-term requests are processed at four occasions per year, on January 15, April 15, July 15 and October 15. Please meet the deadline in order to get a beam time slot convenient for you. Requests on a shorter notice are treated on a first-come-first-served basis, if any beam time remains unscheduled. Normally, within two business days you may expect our feedback to your beam-time request, together with our scheduling suggestion. For pricing, discounts, and invoicing procedures, see TSL beam time pricing policy(CURRENTLY UNDERGOING REVISION 2016-01-12).  The existing beam time allocations can be viewed at the Beam time schedule page.

The following beams are available at the Irradiation Facilities:
Atmospheric-like / white / spallation neutron beam at the ANITA facility (“Atmospheric-like Neutrons from thIck TArget”)
Quasi-monoenergetic neutrons (QMN) with the peak energy of 175 MeV,
Monoenergetic protons at the PAULA facility with the energy of 180 MeV.
Quasi-monoenergetic neutrons (QMN) with any peak energy in 20-175 MeV range,
Monoenergetic protons with any energy in 20-180 MeV range,
Heavy ions, from deuterium to argon.

For further details, see the list of available particle beams. If you already submitted your Beam Time Request, you do not need to resubmit it unless it needs to be updated. When the beam time is scheduled, the project leader is asked to fill in the Run Rules form and send it to, not later than 4 weeks prior to the irradiation campaign. Irradiation projects at TSL are governed by General regulation for commissioned activities at Uppsala University.
