12 GeV Upgrade
The Accelerator Readiness Review (ARR) Phase 1B was completed on Oct. 24. The committee recommended that the lab seek approval to begin commissioning of the CEBAF accelerator upon the completion of the Hot Checkout process. The ARR process is an independent evaluation of the lab's readiness to begin commissioning. In the upcoming ARR Phases, the ARR committee will return to evaluate the lab's readiness as lab staff brings the experimental end stations online for commissioning. Up next is ARR Phase 2 Hall A, presently scheduled for the second quarter of FY14.
Center for Theoretical and Computational Physics
An Electron-Ion Collider (EIC) is being considered as a next-generation facility for nuclear physics in the U.S. and worldwide, and this type of machine presents an exciting prospect for Jefferson Lab after the 12 GeV Upgrade. A "QCD Frontier" workshop was held at Christopher Newport University on Oct. 21-22 to review the EIC physics program in the context of other future high-energy facilities and explore synergies and novel approaches. The common goal of these experimental efforts is to understand the structure of hadrons and nuclei on the basis of the fundamental theory of strong interactions, Quantum Chromodynamics (QCD). The international meeting brought together more than 40 experts in experimental and theoretical nuclear physics and enabled many new contacts between researchers specializing in different energy ranges and reaction channels.
The Alignment group has continued to finish final alignment (termed "Step 2B") in the southwest extraction region and southwest transport section. All the septum magnets YA/YR/YB/ZA's in this region have been aligned and all the multiple-pass beam pipes (more than one beam in an individual pipe) have had their final alignment completed. Final alignment of the last recombiner has begun. Additionally, the group has completed Step 2B alignment of the components to the Hall D tagger area. Finally, the group has supported the new installations in the injector region. In other areas, preliminary alignment of the components to Halls A and B has started, and a C-50 cryomodule was fiducialized in the Test Lab.

Fall Insects and small critters
Most, if not all, of these creatures would rather avoid humans. However, they will react if trapped or disturbed to protect themselves, and they can lash out at people.
We, as the intelligent half of the encounters, should think ahead about when and where we may find them. Whenever possible, we should leave them alone until the professionals can correct the issue. Generally, in order to obtain professional assistance with an insect or animal problem, you should call Facilities Maintenance or put in a Facilities work request and describe the problem and its location.
If you have direct contact, such as having been bitten or stung, report it to Occupational Medicine immediately at x7539.
