12 GeV Upgrade

The first Barrel Calorimeter (BCAL) module for Hall D is being measured for uniformity and optical properties at the University of Regina, Saskatchewan, Canada. The second module has been stacked and machined to tolerance. The third module is being stacked on a second production table, which enables two modules to be assembled in parallel. Optical tests for the preferred BCAL read-out system, silicon photomultiplier arrays, have successfully concluded using prototypes from one vendor. Further testing, including prototypes from a second vendor, is planned. The Hall D forward drift chamber (FDC) preproduction prototype has been assembled and is undergoing testing in the cosmic ray stand at JLab. A set of 40 preamp cards using a custom ASIC chip designed for the FDC read-out is being procured for extended testing of this detector.

Physics

The eighth and final coil of the Q-weak toroid magnet has been installed in Hall C. After final alignment and connection of the 10,000 Amp power supply, the magnet will be tested and mapped. The Hall C Users meeting will be held this Friday and Saturday.

Speaker Nomination for the 2010 DNP Fall Meeting
Speaker nomination forms for the 2010 DNP Fall Meeting are due Feb. 1.

Summer 2010 SULI Program Applications Due
The submission deadline for the summer session of DOE's Science Undergraduate Laboratory Internships program is Feb. 1. This program places students in paid internships in science and engineering at any of several DOE facilities. Students work with scientists or engineers on projects related to the laboratories' research programs, including JLab. The summer programs run from late May to mid-August; specific start dates depend on the laboratory and will be given to participants who have been accepted at that specific laboratory. Key dates in the application submission and acceptance process are available online. Students may continue to complete and submit applications after the labs begin making selections for internships; however, applications submitted after this date may not be read by the lab.

JSA/JLab Graduate Fellowship Program
The deadline for applications for the JSA/JLab Graduate Fellowship Program for the 2010-2011 academic year is next Friday, Jan. 22.

JSA/JLab Sabbatical Support Program
The deadline for applications for the JSA/JLab Sabbatical Support Program for the 2010-2011 academic year is next Friday, Jan. 22.

Accelerator

Work continued in the injector with the completion of the A1-A2 girder bakeout. The maintenance on the 40 MVA substation by Dominion Power took a little longer than anticipated due to a failed load switch that had to be replaced. The Low-Conductivity Water controls upgrade in the North Access Building was completed. LCW pipe welding continued in the tunnel. The cooling tower pump motor and several fan motors had to be replaced. The cryomodule previously at 2L21 was removed and placed in the FEL. Northeast stub dump demolition continued. The Central Helium Liquefier started the cooldown cycle of the Standby Refrigerator.

Free-Electron Laser

A new module has been brought to FEL Zone 3 that should provide an additional 20 MeV of energy to the beam. This is expected to improve FEL performance at short wavelengths. The FEL team received informal notification of two Joint Technology Office awards. One involves North Carolina University at Charlotte on mirrors. The second is with Argonne National Lab and Brookhaven National Lab, among others, on accelerator studies. Also, the team has formally submitted a Field Work Proposal to DOE for the JLAMP Soft X-ray FEL.

Theory Center

Nucleon properties are investigated in a new lattice QCD simulation <arXiv:1001.1131 [hep-lat]> using a novel method involving background electric fields. Employing an ensemble of anisotropic gauge configurations with dynamical clover fermions, magnetic moments and electric polarizabilities are determined for both the neutron and proton. A current limitation, however, is the restriction of the simulations to electrically neutral sea quarks, which will be relaxed in future studies.

Environment, Safety, Health & Quality

A great approach to planning work safely is to ask yourself: "what is most likely to cause my next injury on the job?" Answering this question yourself or during a 'toolbox' safety discussion can often bring overlooked hazards up for discussion.

Human error is responsible for 80 percent of all Army aviation accidents. Army aviators use a self assessment tool for evaluating their awareness of their most likely accident and what measures are in place to prevent it. Their self assessment evaluates individual willingness to meet standards, willingness of line management to 'manage' performance to standards, training to those standards and task-specific training, and support (supplies, tools or equipment) for the task.

Ask yourself what your most likely injury is on the job and how you can adjust your personal practices, encourage those you supervise and plan for success with that knowledge.

Computing and Networking Infrastructure

IT Helpdesk Hours
Starting on Feb. 1, the IT Helpdesk will be open from 8 a.m.-4:30 p.m., Monday-Friday.

Attention JLab Smartcard Users
If you use a JLab smartcard to log on to your system, it needs to be renewed at the Computer Center Helpdesk between Jan. 27 and Feb. 18. All JLab smartcards that have not been renewed by Feb. 18 will cease to function. Renewal takes only a couple of minutes, but requires you and your smartcard to be present at the Helpdesk. Details about smartcard renewal can be found on the JLab Computing webpage.

CNI Maintenance Day Set for Jan. 26, 5-10 p.m.
The CNI group is planning a maintenance period from 5-10 p.m. on Tuesday, Jan 26. During this time, the site may be impacted as follows:
-- The CUE webservers and other systems will go down for a short period as the underlying systems are being modified and certificates updated. All CUE webservers should be back up by 10 p.m. with the new certificates installed.
-- Various network switches will be rebooted for code upgrades. As the group works on individual switches, users may see an outage for no more than 15 minutes; all networks will be back up by 10 p.m.

Proper Disposal of Non-working UPS Boxes
The Property office has observed a number of possibly defective or unused UPS (uninterruptable power supply) boxes around JLab. Property staff would like to remind the JLab community on the appropriate way to dispose of UPS boxes that are not working properly. To dispose of a bad UPS, go to the Property webpage. Click on: Custodian Re-Assignment/Property Relocation and Disposal Website and then select: Submit disposal/excess of "administrative" property not on your inventory. Fill out the web-based disposal request. This will automatically generate a work order to have the UPS picked up. 

For more information about a specific UPS unit, check the owner's pamphlet or contact the Helpdesk at x7155. For questions regarding excessing and properly disposing of JLab property, contact the Property office at x7348, x6270 or x5972.
