Each light source user group should have a user financial account to procure gases, chemicals, supplies or services to support your experiment at SLAC’s user facilities and to send samples, dewars, or other equipment between SLAC and your institution (FACET users do not need to establish a user account). The most common method of establishing or renewing a user financial account is by providing a purchase order (PO) (or a letter from the financial officer of the user institution). The PO should be made to SLAC National Accelerator Laboratory for the amount of expenditures desired to support user experiments. The PO should include the following information:

  • Name of Proposal Spokesperson, PI, users
  • Contact name and billing address for invoices
  • Amount authorized ($2,000 suggested minimum; contact staff if estimates needed for supplies or services)
  • Period covered, including expiration date
  • Funding agency, grant/contract number, and whether expenditures are taxable in California

Contact User Research Administration to determine if you have a current user account or to open a user account.
