The 12 GeV Upgrade Science and Equipment (pCDR June 11, 2004)
The 12 GeV Upgrade is a unique opportunity for the nuclear physics community to expand its reaches into unknown scientific areas. For the first time, researchers will be able to probe the quark and gluon structure of strongly interacting systems to determine whether QCD (quantum chromodynamics), the theory believed to describe strong interactions, gives a full and complete description of hadronic (3 quark) systems. Jefferson Lab at 12 GeV will make profound contributions to the study of hadronic matter-the matter that makes up everything in the world.
In particular the 12 GeV research program will allow breakthroughs to be launched in five main areas:
Through the search for exotic mesons, in which gluons are an unavoidable part of the structure, researchers will explore the fascinating and complex vacuum structure of QCD and the ...
At the request of DOE's Office of Nuclear Physics, Stephen Meador, Director of the Office of Project Assessment in DOE's Office of Science, convened a team of six experts and six observers for a Status Review of the 12 GeV CEBAF Upgrade Project at Jefferson Lab held May 10-11. The purpose of the review was to evaluate the project's readiness for approval of Critical Decision 4B (CD-4B), Project Completion, by Sept. 30. The review team found that the Project's scope is complete, with the exception of the Hall B Solenoid. The review team congratulated all team members working in support of the 12 GeV Upgrade Project on the "real and substantial progress" since the review held last October and provided two recommendations in the Closeout Report.

Instructions for when an Operational Safety OSP) is required in the Physics division can be found in the Physics Division Work Planning Requirements at https://www.jlab.org/user_resources/PFX/NP- PFX/PhysicsDivisionWorkPlanningRequirments.pdf
The OSP process is divided into 3 parts:
1. The OSP form
2. The Task Hazard Analysis (THA) form
3. The Submission form
The official instructions for the OSP can be found at https://www.jlab.org/ehs/ehsmanual/3310T1.htm
The OSP form can be found here https://www.jlab.org/ehs/ehsmanual/3000.html under section 3310 Operational Safety Procedure Form. Just click to the right for the word document.

The following are Physics Division requirements related to work planning, control and authorization for projects and test set ups in all Physics division work areas across the laboratory. When planning the testing and commissioning of experimental equipment, careful consideration should be given to the hazards, consequences and cost of that equipment when doing the risk analysis. Things to consider are;
Location - Requirements such as power requirements, water, gas, cryogenics, safety boundaries
Dimensions, weight - How will it be held? If a support structure is used, who did the design/fabrication? How will it be positioned and moved?
Special Hazards associated to build/operate the setup - flammable materials, oxygen deficiency hazard, high pressure, radioactivity, toxic or noxious fumes, Repetitive...

This document was developed to provide experimenters with a basic guide to what is required by JLab when equipment or materials are brought here from other facilities and for procurements made outside our procurement system. This guide will give an overview of the requirements and links to the relevant chapters and Subject Matter Experts (SMEs). The EHS&Q manual can be found at https://www.JLab.org/ehs/ehsmanual/index.html. The SME list can be found at https://mis.JLab.org/mis/portal/hazard_list.cfm?noheader=1. Your SOTR/ Sponsor should be your first point of contact for information or questions. If you are not sure who that is, feel free to contact me and we’ll find out.

The Hall-C Moller Polarimeter measures the polarization of the electron beam arriving in Hall-C. It does so by observing the rate of production of Moller electrons at 90 degrees in the center of mass when the beam strikes a thin iron target. The outer shell electrons in the iron are polarized parallel (or anti-parallel) to the beam direction by a 4 Tesla magnetic field. The Moller electron production rate differs when the beam and target electron spins are aligned parallel or anti-parallel to one-another. Measurement of this rate difference provides a measure of the beam polarization.
The Hall-C device is designed to provide an absolute polarization measurement with accuracy better than 0.5%. A system of movable collimators and a pair of quadrupole magnets allows the system to be tuned to operate at any beam momentum between about 0.9 ...
Hall C maintains two general interest mailing lists. To subscribe to these lists, go to the link below and follow the "Subscribing to" instructions. A list of other public Jefferson Lab mailing lists is available.
The Hall C Email list is used to announce weekly and semi-annual Hall C meetings and for general announcements and news. Archives of previous Hall C mailing list postings are available. (Postings from before July 2009.)
The SHMS Users Email list is used for periodic news about the Super HMS and Hall C 12 GeV upgrade. (Archives)
The Hall C Analysis Software mailing list is the forum for announcements and discussions related to the development of Hall C software for 12 GeV. (Archives)
