Steps to Conduct Research at the Tandem

Review Tandem's Capabilities

Review the informaiton (below) to ensure that the Tandem can meet your research needs.

Many other ions can be produced if required. We have to know, in advance, what ions and LETs you plan to use. In addition to the maximum energies, ranges and corresponding LETs listed below, lower energies are available for each ion. Charts for range and LET values as a function of energy can be seen by clickingon the links in the LET columns.

Flux can be in the range of 1 particle/cm2/sec to greater than 1 · 106 particles/cm2/sec.					In Silicon High LET Summary Low LET Summary		In GaAs High LET Summary Low LET Summary

Check Tandem's Availability

Check the schedule to ensure that beam time is available when you plan on using the Tandem.

Request Beam Time

Thank you. Your request has been submitted.

Submit Form ▼

Submit Safety Approval Form

Users are required to complete and return a Safety Approval Form (PDF), at least 14 days prior to the start of a run. Return completed form to Sarah Cormier, scormier@bnl.gov

Submit Guest Registration

Individuals who do not hold a valid BNL ID who plan to come to Brookhaven are required to register in BNL's Guest Registration System (GIS) a minimum of 10 days in advance of their visit.

Pay close attention to the e-mail instructions you will receive after you register and after you submit the BNL arrival notification (separate step, below).

If you have an expired BNL ID, then email the Guest, User, Visitor Center, or call (631) 344-3333, to determine what is required to reactivate it.

Under certain circumstances, approvals can take from 30 to 90 days to obtain, so be sure to allow enough time to obtain the required approvals.

Establish or Verify Agreement With BNL to Cover Research

If you are conducting research at one of BNL's user facilities, a user agreement signed by your home institution is a prerequisite for experimental work. Guests are not permitted to do experimental work at any of Brookhaven's User Facilities until a User Agreement with your home institution is established.

To work at the Tandem you must have either a proprietary agreement, open data agreement, or both in place to cover your research.

How to Request a User Agreement

If your institution does not appear in this list,, then complete the User Agreement Questionnaire, which is the first step toward putting a master user agreement in place. Fill in the requested information and Brookhaven will furnish the appropriate User Agreement(s) to your institution for signature. This form may be submitted electronically by completing the questionnaire below and clicking the submit button or by printing and returning via fax to 631-344-8686. Printable Version

Non-DOE Users (w/ S&S & FCR) (Most Users fall into this category)	$2,560.00
Non-DOE Users (w/ S&S; FCR & FIE) - DoD	$2,662.40

*Beam Rates are typically effective for the calendar year; however, all rates are subject to change.

Contract & Payment Procedures

Non-Federal Users, including universities and industry, require a Strategic Partnership Project (SPP) agreement with BNL, along with FULL PAYMENT OF EACH RUN MUST BE IN-HOUSE PRIOR TO THE RP & DOE DUE DATE TO BE SCHEDULED AFTER THE DOE CONTRACT MODIFICATION APPROVAL DATE (Approximately the 20th of each month). Note that processing time for an SPP agreement may take up to 60-90 days for domestic entities (90 days or more for foreign entities). As such, we encourage you to start the process early!

Federal Users, including DOE, other DOE Laboratories and Federal Agencies, require an interagency purchase request (IPR) for the full amount of beam hours to be provided. Your IPR should be provided at least 30 days in advance of your planned beam time.

All users require a Statement of Work (SOW) in order to start the process. Please coordinate the SOW with your Administrative contact named below.

For Example: If planning to run in February 2024, all agreements must fully executed, and funding must be in- h ouse before the January 11 due date for the run to be scheduled. Any run scheduled in a month, must be approved by DOE the prior month.

Submit BNL Arrival Notification

To access the BNL site, all guests must notify Brookhaven of their actual arrival date by completing the Arrival Notification Form on the Guest Central website. If you fail to do this, then access to the Brookhaven site could be declined or you may be delayed at the front gate.

Arrange for Houseing

You may wish to arrange for on- or off-site housing accomodations for your visit.

• On-site housing
• Off-site housing

Complete Required Training

The following training courses are required prior to using the Tandem:

• Cyber Security
• Computer Use Agreement
• Guest Site Orientation
• General Employee Radiological Training
• Basic Electrical Safety
• Active Shooter Training

A valid BNL guest number is needed for training. If you have a valid BNL guest number, you may check your training status.

Prepare for Arrival at BNL

You must bring identification with you: Identification Requirements

Figure out how to get here: Maps & Directions to Brookhaven Lab

If you are staying on site, then you should pick up your room key upon arrival. The Housing Office is open Monday through Friday, from 8 a.m. to midnight; Sunday, from 4 p.m. to midnight. If you are arriving or departing at other times, then you may pick up or drop off keys at Police Headquarters. Checkout time is 1 p.m. Before leaving, return your keys to the Housing Office and pay your housing bill.

All guests and users are provided with check-in procedures by e-mail when they submit a registration form to come to BNL. Guests can check their appointment and training status and what BNL identification documents are on file by visiting Guest Central.

All guests, users, and visitors must check-in at the Guest, User, Visitor Center, which is located in Building 400A prior to visiting their department and/or user facility. Check-in hours are from 7 a.m. to 5 p.m., Monday through Friday, excluding holidays. Guests should make every attempt to arrive during these hours.

All Tandem users must sign a Commitments and Expectations Statement and have a user agreement in place prior to conducting any research.
