While You Are Here

To Enter SLAC You Must Have ID and Your Safety Training Must Be Current.

Review preparation, arrival and check-in information. Plan to arrive at SSRL between 8:00 am - 2:00 pm, Monday through Friday, except Holidays. A knowledgeable person from your group should be available for consultation by the SSRL staff readying the beam line for your group the morning you are scheduled to begin. Potential safety hazards must be disclosed in advance, and an Experiment Safety Checklist (SCL) must be completed by the Operations staff before user experiments can begin.

See resources for lactation support below.

Safety Matters

User Badges/Safety Guidelines/Safety Orientation

All onsite users must complete web-based SLAC safety training in order to obtain a SLAC ID and proximity access from Security. There must be a user agreement with the users' home institution, and users must review the Access Guidelines and annually complete an Acknowledgement. Safety talks for new users are given 2 pm (except weekends, holidays and AP/PAAM days).

Dosimeters

SSRL users are generally not issued dosimeters unless they may work in a Radiologically Controlled Area or handle radiactive sample materials while at SLAC/SSRL. Discuss and disclose these issues with the SSRl Safety Officer and, if needed, obtain a dosimeter from SLAC Security at the SUSB. Return dosimeters to Security before departing from SLAC.

Hutch Operation

Search reset (SR) keys must remain on the premises at all times. Contact the SSRL Duty Operator (DO)/Floor Coordinator for questions or assistance with SR keys, beam line or hutch operation.

Other ES&H Concerns

All equipment that is brought to SSRL must meet accepted standards for good laboratory and electrical practices.

Any hazardous waste, including solvent wipes, must be disposed of properly, i.e., not in the regular trash receptacles and not mixed inappropriately. There are disposal containers available on the experimental floor. For procedures for disposing of hazardous waste through SSRL see the section on Leaving SSRL.

Please list your local telephone numbers on the white board at your beamline so you can be contacted if questions arise or in case of an emergency.

Operational Matters

Check the SPEAR operating and beam line schedules for information on beam time as well as dates when SSRL will be DOWN for Maintenance, Accelerator Physics or Holidays so that you can plan your visits accordingly:

SPEAR Status

Updates on the status of SPEAR and beam lines are available on line. A recorded SPEAR status message is also availble at 650-926-BEAM(2326).

Changeover Shifts

X-ray Lines
Although beam time officially turns over to the next user at 3 pm, a knowledgeable user should arrive by 8 am to assist staff if questions arise about the user's experiment configuration preferences. Beam lines are usually available much earlier in the day so the experiment team is advised to arrive early (~10 am-2 pm) on their first day of beam time. Contact the designated beam line engineer/scientist at least one week prior to your experiment to discuss your beam line configuration needs and confirm your start time. First time users should arrive a day to complete safety training and hutch authorization. Unless other arrangements have been made with your beam line contact, plan to complete experiments, clear and clean up the beam line by 7 am on your last day when set up for the next user group will begin (beam time ends at 6 am on designated MA/AP days).

VUV Lines
Although beam time officially turns over to the next user at 3 pm, a knowledgeable user should arrive by 9 am to assist staff if questions arise about the user's experiment. Beam lines are usually available much earlier in the day so the experiment team is advised to arrive early (~10 am-2 pm) on their first day of beam time. Contact the designated beam line engineer/scientist at least one week prior to your experiment to discuss your beam line configuration needs and confirm your start time. First time users should arrive a day to complete safety training.Unless other arrangements have been made with your beam line contact, plan to complete experiments, clear and clean up the beam line by 7 am on your last day when set up for the next user group will begin (beam time ends at 6 am on designated MA/AP days).

Macromolecular Crystallography Lines
Beamline 7-1, 9-1, 9-2, 11-1, 12-2, and 14-1 users will go online at 3 pm and come offline at 11 am.

Changes to the Experimental Schedule

Contact the User Research Administration Office as early as possible if changes to the experiment schedule are needed (C. Knotts/T. Nakai for X-ray and VUV and L. Dunn for Macromolecular Crystallography).

The Experiment Safety Checklist (SCL) will be extended after the User Administration staff have updated the beam line schedule and informed the Operations group of the schedule change.

Program Manager Rounds

On weekdays, at approximately 3:00 PM, the Beam Line Program Manager and the Duty Operator tour the floor, stopping at beam lines to interact with users, answer questions, provide assistance, and obtain user feedback.

Accelerator Physics (AP)

48 hours of accelerator physics or maintenance are scheduled every other Monday-Wednesday (6:00 AM through 6:00 AM). Occassionally there may be parasitic beam available during AP/PAAM activiteis. Contact the Beam Line Program Manager for more information. Decisions about use of usable beam needs to be coordinated with AP, URA, beam line staff, scheduled changeovers, equipment availability, etc.

Lactation Support

For women who wish to carry out their breastfeeding goals, we seek to provide an accommodating and supportive environment for lactation while at SSRL and SLAC.

There are several dedicated Mothers' Rooms at SLAC located in:

Building 53 (Room 3074 - SUSB)

Building 901 (Room 204 - LCLS)

Building 28 (Occupational Medicine)

Building 41 (Room 1272)

For women interested in space closer to SSRL beam lines to most effectively utilize scheduled beam time to conduct their experiments, there is a private shower/dressing room located above BL4 and BL13 on the second floor of Building 130 (Room 212). This room is conveniently located next to the rest rooms and around the corner from a kitchen/lounge with a refrigerator.

If use of a different space is desired, contact your supervisor, URA or SSRL point of contact to discuss possible alternative arrangements for meeting lactation space needs, which might include scheduling conference rooms, using an unoccupied office (with permission) or hanging temporary blinds or curtains to create a private space. Any space that is private and not a bathroom can be considered as a lactation space.

Before Leaving SSRL

Return Borrowed Equipment

All equipment borrowed from SSRL must be returned before you depart (equipment which is not returned will be billed to you).

Dispose of Hazardous Waste

Hazardous waste which needs to be removed from the site is handled by SLAC. SLAC personnel must be contacted through SSRL staff. If you have waste to be removed from one of the SMB Sample Preparation Laboratories, please fill out the appropriate form in the lab and contact Cynthia Patty. If you have hazardous waste to be removed from other parts of the lab contact Cynthia Patty (ext. 3925) or Matt Padilla (ext. 3861) to get the appropriate forms. It is important that Cynthia or Matt speak with you in person regarding the waste before you leave the site.

Ship Equipment

See instructions related to shipping equipment back to your home institution. If you plan to ship samples, equipment or other scientific items from SLAC back to your international institution or to another location outside of the U.S., review foreign shipping/export instructions and complete a Power of Attorney form for the Individual  or Group that is responsible for and who will receive the shipment. .
