Becoming an SSRL User
There are several mechanisms that can be used for obtaining beam
time on macromolecular crystallography beam lines at SSRL.
Standard General Use Proposals
The most common way to obtain access to our macromolecular
facilities is to submit a standard proposal for review by SSRL's
Proposal Review Panel. Although proposals can be submitted at any
time, review deadlines are set for April 1, July 1
and December 1 of each year. Once rated, proposals are eligible for
beam time starting the next scheduling period (normally there is a
2-3 month period between proposal submission and beam
time). Standard single experiment proposals are eligible for beam time
for a two-year period (6 scheduling periods). Program proposals
are eligible initially for two years as well, but extensions may be
requested if the research project extends beyond two years.
For more details see:
Proposal Submittal and Scheduling Procedures for Macromolecular Crystallography
Rapid Access Proposals
Normally ~2.5-5 shifts are reserved on the schedule for Rapid Access
beam time. Applications are submitted through the User Portal and reviewed by SSRL's Proposal Review Panel
for scientific merit and feasibility within a short turnaround
(less than 1 month) and the proposal receiving the highest rating
will be granted some or all of the shifts held in reserve.
Applications that do not receive the highest rating, but are
approved for beam time, are given consideration when cancellations
occur and for future Rapid Access shifts.

New Multi-Technique Proposals
A new Multi-Technique Proposal mechanism (pilot phase) has been created for projects that require the use of two or more scientific techniques available at SSRL (this includes both x-ray and EM). The pilot proposal mechanism will initially cover Macromolecular Crystallography, Small Angle X-ray Scattering, and Cryo-EM. A goal is to expand it in the future to include additional techniques such as those available at LCLS. The new pilot proposals will require a thorough justification as to why the two or more techniques are required for scientific success. The proposals will be reviewed by an ad hoc Proposal Review Panel comprised of members of the SSRL SMB and Cryo-EM PRPs. The new proposal will be available June 1 and the first deadline for submission will be July 1.
Participating Research Teams
Though many of SSRL's beam lines are primarily devoted to general
use access, several institutions have set up Participating Research
Team agreements. For more information regarding
macromolecular crystallography PRTs, contact: Mike Soltis.
Collaborations with SSRL Scientific Staff
If you are interested in establishing a collaboration with a member
of the SSRL staff, have an unusual experimental set-up, or have
inexperienced group members who need training, please contact: Mike Soltis.
Please note that regardless of the mechanism used to obtain beam
time, a valid
Use Agreement must also be executed between your institution and
Stanford University before an experiment can be carried out at
SSRL. Contact Michelle
Steger to determine if an executed agreement is in effect. If your
research is proprietary, you must adhere to the policy and procedures set up for
proprietary research at SSRL and set up an
Use Agreement for Proprietary Research. Users performing
private sector research will be required to pay a fee based on full
New users are required to obtain a Unix
account before the experiment starts. Contact Edgar Estebanez for
questions about accounts on the crystallography server.
All users are responsible for the incidental costs of research at
SSRL including shipping, stockroom supplies, gases, phone charges,
etc. Establishing an account at SSRL to offset these expenses
is highly recommended. See
User Accounts for more information or contact Michelle
Steger. You may also use your institution's account with Federal
Express, UPS, or Airborne Express, etc., to pay for shipping
charges, but delays in shipping your dewar back to your home
institution may occur if group members do not have access to the
account number or give incorrect information.
