3120 Appendix D The Experiment Review Process for a New Experiment
Using the Base Equipment (Type 2) |

1.0
Proposal
Phase
1.1
Conceive experiment, and carry out preliminary design work for the new
equipment required.
1.2
Identify ES&H Issues associated with the New Equipment, and with
the Safety
Envelope for beam operation in the hall, and fill in an ES&H Hazard
Identification Check List.
1.3
Submit proposal to Jefferson Lab.
Each proposal must include a filled-in ES&H Hazard Identification
Checklist (see ES&H
Manual Chapter 3120 Appendix H Checklists for Experiment Preparation and a Beam
Requirements List (see ES&H
Manual Chapter 3120 Appendix H
Checklists for Experiment Preparation.
1.4
Preliminary review of technical aspects of the proposal by the
Jefferson Lab Technical Advisory Committee (TAC).
1.5
Review of the Scientific merits of the
proposal by the Jefferson Lab Program Advisory Committee (PAC).
1.6
Decision by the Director of Jefferson Lab to grant beam-time.
1.7
Jefferson Lab assigns a Physics
Division Liaison and an ESH&Q Coordinator (often the same individual) for
the experiment.
2.0
Design Phase
2.1
Calculate
and document Experiment
Operating Envelope (EOE) for all combinations of beam conditions and
target(s) planned. Identify Safety
Issues for EOE. (For this type of experiment it is assumed
that NO mitigating measures will be required beyond those already built into
the existing equipment and procedures. If this is not the case the experiment should
be treated as type 3 or 4, and more detailed review will be required.) Decommissioning plans for target and
activated components must also be developed as appropriate. Submit a formal Radiation Safety
Assessment Document (RSAD) for the experiment that explicitly includes the
calculations of the EOE and
addresses the ES&H issues it raises.
2.2
Complete a final safety analysis of the equipment and write a formal Experiment
Safety Assessment Document (ESAD). This
document will be straightforward for a type 2 experiment - basically one page
referencing the base equipment ESAD and the
RSAD (see 2.1
above).
2.3
Review of the ESAD (by
Jefferson Lab’s E2RC) and the RSAD (by
Jefferson Lab is RadCon
Group).
(These reviews will
generate the basic Experiment Installation Checklist, or EIC, identifying items
and to be checked at installation prior to issuance of the Experiment Readiness
Clearance; a sample EIC is provided in ES&H Manual Chapter 3120 Appendix H Checklists for Experiment
Preparation. Typically, if
the experiments contribution to the laboratory’s overall radiation
budget for the year exceeds their pro-rata portion by a factor of two or more,
they will be asked to consider additional measures such as local shielding. Issues or concerns raised
during the course of this or subsequent reviews will be entered onto the
experiment's Issue/Concern Checklist, or ICC.
A sample ICC is provided in ES&H Manual Chapter 3120 Appendix H Checklists for Experiment
Preparation.)
2.4
Additional review of the RSAD by the Jefferson
Lab Radiation Review Panel (JRRP) or an ad hoc panel if the planned EOE exceeds
the previous maximum for the Hall and the RadCon
Officer deems it appropriate.
(This
review may generate additional items for the EIC and/or ICC)

Preliminary
Scheduling of Experiment by Jefferson Lab
4.0
Preparation
for Running the Experiment
4.1
Personnel and Procedures:
4.1.1
Describe Experiment Procedures,
Collaboration Organization, Operations Personnel, Training Required,
etc. in a written Conduct of Operations Document (COO).
(Note the bulk of the
experiment procedures
will be in the form of an operations manual for the major experimental
equipment that will be referenced by the COO.
4.1.2
Review and approval of the COO
by Jefferson Lab’s TAC.
4.2
Equipment Installation: Install
target and verify operation of equipment necessary to ensure operation within
the approved safety
envelope.
(Note the ESAD and RSAD for the
experiment must be approved by the E2RC and RadCon
Officer respectively prior to installation of the target.)
4.3
Pre-operation checkout of
equipment installation and procedures
by experiment collaboration. This serves
to verify operability after installation and to review integration to the
extent possible without the use of beam.
4.4
Jefferson Lab review of the safety of the installed equipment prior to
its use.
(This review will be
carried out by Division ESH&Q Personnel and the assigned Physics Division
Liaison, verifying conformance to the ESAD and
checking functionality of safety aspects of the apparatus and items and issues
specifically identified on the Experiment Installation Checklist by the
reviews.)
4.5
Experiment Readiness Clearance (ERC) issued by AD for Physics.
(Note
this will include a verification that all reviews are in place, as denoted in
the Experiment Readiness Checklist of ES&H Manual Chapter 3120 Appendix H Checklists for Experiment
Preparation.
It also verifies that the experiment installation check has been
completed, as documented on the Experiment Installation Checklist, and that all
issues and concerns have been satisfactorily resolved, as detailed in the
Issue/Concern Checklist.)
5.0
Final Scheduling of Beam Time by
Jefferson Lab
6.0
Commission equipment (following written procedures
documented in COO)
(Note
if planned EOE
is outside the previous maximum for the Hall, commissioning procedures
will incorporate radiation safety verification measurements as required by the
Jefferson Lab RadCon
Group.)
7.0
Run the experiment (following written procedures
documented in COO)
(If the
equipment changes at any time over the course of the experiment, the spokesperson
must notify the hall leader and the E2RC
chair, in writing. Such changes might
include changing inert to flammable gas mixtures, for example,
or changing from a non-hazardous to a hazardous target material. The hall leader and the E2RC
chair will determine whether the change requires a revision of the experiment’s
ESH&Q documentation and/or additional formal reviews.)
8.0
Decommission the temporary equipment (if
appropriate) and store or dispose of target and/or contaminated apparatus
properly
9.0
Based on the
experience gained during the experiment:
9.1
Update ESAD
for equipment (providing an improved ESAD for the
base equipment).
9.2 Update written procedures for equipment use (resulting in an improved Operating Manual for the base equipment).
