ESTB Proposals Submission and Review Process
ESTB Scientific Committee (SC)
-Appointed by SLAC Management (PPA-ALD)
-Evaluates and prioritizes proposals
There are two fundamentally different types of experiments which can be conducted at ESTB:
-Accelerator physics experiments like machine detector interface, linear collider beam delivery studies
-Detector R&D experiments including radiation tests
The ESTB Scientific Committee will direct accelerator physics experiments to be reviewed by SAREC (SLAC Accelerator Research Experimental Program Committee)
All other proposals will be reviewed directly by ESTB SC

For detector R&D or radiation tests user submits a comprehensive proposal which includes:
PI, members and institutions involved
Short description of the overall physics goals
Detailed description of the experimental apparatus
-Sketch of the planned layout with dimensions
-Description of the DAQ system coming with the experiment and what additional DAQ will be needed from SLAC
-Other electronics components (HV supplies, scopes, etc.) 
-Cooling or gas supply needs
-Computing infrastructure needs
-Any other aspect which might be of importance
-Support needed from SLAC: riggers, technicians, DAQ systems, cooling, gas lines, etc.

Preferred beam parameters and acceptable beam parameters
Estimated installation time
Run plan (e.g. how many data points, how many modifications of the apparatus, etc.)
Preferred running time
Any other aspects of importance

Proposal (2-5 pages) is submitted to C. Hast (
Proposal is reviewed by ESTB Scientific Committee
C. Field, P. Grenier, C. Hast, B. Ratcliff + additional members (as needed)
Accelerator physics proposal are send to SAREC for review
Criteria for proposal evaluation:
-scientific value
-evaluation of resources
-scheduling and prioritization
SAREC will provide a prioritized list of their reviewed proposals to ESTB SC
Proposal will be reviewed by SLAC Safety Committees as appropriate (ESTB Operations Manager directs this process)
-Hazardous Experimental Equipment Committee
-Radiation Physics
ESTB Scientific Committee will provide a prioritized list of experiments to the ESTB Operations Manager who will schedule the experiments
Typical turn around for detector R&D proposals between 1 and 3 months

The ESTB Scientific Committee will direct accelerator physics experiments to be reviewed by SAREC (SLAC Accelerator Research Experimental Program Committee)

SAREC has a similar but more elaborated review process
SAREC’s main task is to review FACET proposal. This process is documented here:

SAREC meets once per year, but proposals can be submitted at any time

Next SAREC meeting October 11/12, 2012


After Your Proposal is Accepted

Any experimental setup needs review and approval to be installed and operated at SLAC

Safety Oversight Committee (SOC)
-Looks at experimental equipment and will request Safety Officers and others to review your setup
Test Facilities (TF) is instrumental in getting the necessary approvals for you
-We know how the system works
-We are part of the system
-We can do many things for you – If you tell us what you want to do
-This process can be quite fast for normal setups
-But if you need more exotic components (e.g. hazardous gases) will take more time
Electrical components need to be UL listed (or equivalent)
-Thats a tough one, because many devices you are using in your home institutes are not!
-A European “CE” is not good enough at SLAC
-SLAC has an inspection process to approve non listed devices
TF can do that
We will only allow the operation of approved devices
Radioactive sources need to be registered with RP prior to their arrival

Becoming a User

Users will register with the SLAC Users Organization
SLUO will work with the PI on a generic MoU between Stanford University and your home institution (mainly about intellectual property rights…)
Each individual user needs to agree to that MoU
SLUO will get users a SLAC systems ID and a computer account

We might change to the SSRL/LCLS style user organization, but that will be transparent to ESTB users

A SLAC Contact will be assigned to each experiment and user
This SLAC Contact functions as your supervisor here at SLAC
Carsten Hast will be the Operations Manager for ESTB in FY13

SLAC Contact defines the training requirements
Most training can be done remotely via web training (after you have a SLAC system ID)
Couple of things on first day of arrival

We will setup a web page which will lay out what you need to do
