SBN Collaborators Visiting Fermilab

The coming years we expect many ICARUS and SBND collaborators to come to Fermilab and assist with the installation of the Far and Near Detectors. The Fermilab Global Services Group has an excellent web site to help with everything you need to do. The Global Services combines the Users Office and the Visa Office. You start the process before you arrive by requesting, from online, a Fermilab ID and a computer account; you need both of these to access, from online, necessary training classes. When you arrive at Fermilab, you will be issued an ID only after completing the ID/computing request and taking the necessary training. If you are not a U.S. citizen, you will need additional documents, which includes the appropriate visa you used to enter the U.S.

For all visiting collaborators

Request an ID/computing account

  • Your affiliation is
    • for the Far Detector, E-1052 ICARUS, under Experiments-Approved
    • for the Near Detector, T-1053 SBND, under Experiments-Test Beam
  • Your Fermilab contact is Peter Wilson, Fermilab phone extension 2156, email pjw at

When you receive your Fermilab ID number and computing account, please send your ID and computing user-name to the SBN Experiment Operations Liasons (ELO), The ELOs will set up your training requirements plan, including access to the SBN buildings, and access to the electronic log-books. You will receive an email pointing you to further detailed instructions for taking online training, which can be done before you arrive at Fermilab.

As you pack your bags, make sure you have the Documents required for on-site access listed here

If you are not a U.S. citizen

See the Fermilab Global Services page on Business Visits to Fermilab, which holds basic information on the overall process and holds links to the relevant State Department sites. If you hold a passport from countries in the European Union and some others (such as Austrailia, New Zealand, Japan, South Korea) then you may qualify for the Visa Waiver Program and ESTA. If not then you must apply for a visa; Fermilab Global Services has a detailed page describing the steps to obtain a U.S. visa.

All of these steps take time. If are visiting for several weeks or more and need an invitation letter from Fermilab, then it takes about a week for the SBN Program Office to obtain the letter. You may need to also obtain letters from your home institution. Even when you qualify for the Visa Waiver Program, if you are applying for ESTA for the first time, then the application may take a couple of weeks. Applying for a visa may take a couple of months. Plan ahead!
