Before making travel plans to visit SLAC, ensure that you and your colleagues have correctly identified their institution in the user portal and confirm that a user agreement has been executed by the appropriate official at each institution. If an agreement is not executed in advance, scientists will not be able to visit SLAC or participate in user experiments at SSRL.
The Department of Energy has implemented standard user agreements for Non-Proprietary User Agreement and for Proprietary Research. We have very little flexibility to modify the agreement template. Review the tempate agreements and a list of user insitituions with valid agreements.
Proprietary Research requires a separate agreement and advance payment on a full-cost recovery basis.
The GUEST HOUSE sets aside rooms for users during peak demand periods at Stanford. Identify yourself as a user and include your proposal information. You may also ask to be waitlisted for rooms that become avaiilable.
Prior to traveleing to SLAC, review updated user check-in procedures and changes for automated access/badging. Ensure that URA knows who plans to visit SLAC to participate in your experiment. There are additional requirements for foreign nationals from certain countries. SSRL hosts will be assigned and visits will be coordinated with DOE through the Foreign Access Central Tracking System (FACTS). Advance approval is required for users who were born in, are citizens of, or have had afffiliations with Cuba, Iran, Sudan or Syria.
Identify potential safety issues on proposals and beam time requests (BTR). If there are any potential hazards with your samples, materials you are using, or overall set up, you may be contacted by the safety office depending on the degree of the hazard indicated. If you have any questions about potential hazards related to the substances/equipment you plan to use at SSRL, contact the Safety Office.
Experiments dealing with the following hazards should contact the safety office before making plans to visit SSRL as advance notifications or additional approvals may be necessary:
- Class 2 biohazards, animal and human subject use
- Lasers (class 3r & 4)
- Radioactive materials
- Dry nanomaterials use
If you want to bring hazardous equipment or substances to SSRL and have not previously indicated this on either your proposal or beam time request (BTR), contact the safety office immediately. Additionally, any changes you may wish to make to your proposal or BTR must be reviewed and approved by the safety office in advance. Late changes that involve potential hazards may not be possible.
The experiment information you provide is used by the Safety Office to review safety, potential hazards, mitigations, and appropriate training as well as to generate a Safety Checklist for your experiment which will be reviewed, completed and posted at the beam line before your experiment begins.
If you have been assigned beamtime on an X-ray or VUV line, you must log in to the user portal to accept the beam time and submit a support request for each beam time allocation. Review the beam line, date(s), configuration(s), and collaborator information carefully. Add any collaborators who will be assisting you with this beam time to the list. Only the collaborators listed on these forms will be allowed through Gates 17 and 30 without an escort to SSRL.
Review and provide experimental set up information to indicate the monochromator crystal, mirror position and SSRL equipment requested for your run. If your needs have changed or if there are any problems, contact the User Research Administration (URA) Office immediately. Any necessary corrections need to be coordinated in advance of your visit. Technical support is very limited, and it is difficult to accommodate late requests for equipment or set up changes which were not indicated in advance.
Note: For Macromolecular Crystallography users, support information is collected in the Beam Time Request.
If needed, SSRL user groups should complete this form to establish a user financial account to pay for specialty services from Stanford or SLAC shops, to procure items to support experiments at SSRL, or to pay for shipping items to/from SLAC (if not using their home institution's shipping account). Beginning in FY2017, SSRL is undertaking a pilot program to absorb the cost for gases and liquid helium commonly used for user experiments at SSRL. Updates on user chemicals will be provided shortly. Although a separate user financial account may generally no longer be necessary, unusual requests or items that exceed a threshold will trigger the need for a user financial account.
All chemical orders must be placed through SLAC’s chemical procurement system. Please note that you cannot direct ship any chemicals from a supplier to SSRL. If you need to place a chemical order, please follow the guidelines outlined below. Please begin your chemical order as soon as possible. Note that there is a significant lead time on procuring chemicals. Depending on the hazard of the material, this lead time could be up to 4 weeks.
Create User Financial Account: You must create a user financial account to pay for your chemical order and other purchases you make at SSRL. More information about User Accounts can be obtained at the links below.
Send Chemical Information to SSRL or LCLS: Staff must review your chemical orders for safety reasons. If you need to place a chemical order, please email chemical name, manufacturer’s name, part number, size, date required, user account number, MSDS and a brief description of how you are using this chemical in 1-2 sentences. We will contact you if we need additional information. For SSRL, send emails to
Gases and cryogenics can be charged to your user fiinancial account. With the exception of liquid nitrogen and liquid helium ordered by SSRL for use with SMB cryostats, all gases should be ordered well in advance of your arrival on site. Please complete order forms at least 2 weeks before your beam time for standard gases and at least 4 weeks for speciality gases (including Carbon Monoxide and Oxygen). For questions about gas safety & operating procedures contact .
Liquid Nitrogen: SSRL supplies liquid nitrogen at no charge to users. The main filling station is located in the Bldg. 131 Annex. There is also a smaller tank for filling small dewars. When handling Liquid Nitrogen, please follow the instructions carefully and wear the supplied gloves and safety glasses.
Liquid Helium: Liquid Helium is available on a 2-day turnaround in 100 liter dewars. The cost will be charged to your user account. Liquid helium orders should be placed electronically using the SSRL Gas Ordering Form.
Standard Gases: Orders for standard which will be charged to your user account, must be placed two weeks prior to arrival. Please use the SSRL Gas Ordering Form
Specialty Gases: Specialty gases (including Carbon Monoxide and Oxygen) must be ordered 4 weeks prior to your arrival. There is a charge for these gases which will be applied to your user account. Specialty gases cannot be returned for credit to your account. Please use the SSRL Gas Ordering Form.
Dewars: SSRL has a small supply of portable dewars which may be loaned. Users wishing to ship dewars to SSRL should complete the Shipping Dewars to SSRL Form to help ensure that the dewar is delivered to the correct beam line and refilled if necessary.
Each user group must have a computer account and sign a computer usage security agreement. All persons using SLAC computers or accounts are responsible for understanding and complying with the security agreement. SSRL does not charge for use of its computer systems. Forms are available on the web (form for X-ray/VUV lines) and (form for Macromolecular Crystallography lines). For more information, SSRL X-ray/VUV users should contact Ellie Fazli, macromolecular crystallography users should contact Thomas Eriksson.
See instructions for shipping equipment and samples to or from SLAC. Note: There are new requirements for international shipments and exports. Please coorindate in advance.
For information on personally transporting samples or other potentially hazardous materials, contact the Safety Office.
