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 what you need to do. The Global Services combines the Users Office and the Visa Office. You start the process before you arrive. Request, via web pages linked below, a Fermilab ID and a computer account; you need both of these to access the required online training classes. When you arrive at Fermilab, you will be issued an ID only after completing the ID/computing request and online 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

Contact the SBN Program Administrative Support - Stephanie Schuler . Tell her the dates you plan to be at Fermilab; she will assist you through the steps, outlined below, to obtain an ID badge on your first visit and re-issue of your badge on repeat visits.

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 number and computing user-name to the SBN Experiment Operations Liasons (ELO), The ELOs will set up the list of required training (called an ITNA), which is based on the experiment area you entered as your affiliation (ICARUS or SBND). The required training includes classes needed to gain access to the SBN buildings. Once the ITNA is set up, you will receive emails holding links for taking the online training and accompanying online tests. All these online trainings 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!
