POWGEN Mail-in Program

The mail-in program is temporarily suspended due to the extended Proton Power Upgrade outage. The return of neutrons is planned for July 2024.


Mail-In Program Overview

  • Proposals are accepted at any time.
  • A number of days are reserved from the general user program each cycle.
  • It is expected that samples are ready before the mail-in proposal is submitted.
  • A maximum of 8 hours can be requested in each cycle.
  • Temperatures between 10K and 300K can be requested but the total time cannot exceed 8 hours.
  • Once approved, vanadium sample cans are sent to the users to be filled and returned to the SNS.
  • Samples should be returned to SNS within two weeks of receiving the empty cans. 
  • Experiments are measured on a first-come, first-served basis.

  5. Load your sample cans, according to the instructions linked below, and fill out the sample loading spreadsheet in IPTS.
  6. Ship the loaded samples and loading spreadsheet back to the address linked to in the notification email.
  7. Your samples will be measured at the first available opportunity, on a first-come, first-served basis.
  8. You will receive an email when data collection is complete.  Follow the directions and linked guides on the Powgen User Guidance page to download and analyze your data.
  9. All publications resulting from your Powgen data must include the SNS acknowledgement and should be submitted to the PuSH publication tracking system.
  10. After 30 days, your samples will either be wasted or shipped back to you, based on what you requested in the proposal.
