12 GeV UpgradeThe R&D task to re-measure the higher-order mode (HOM) damping in the 12 GeV Superconducting Radio-Frequency (SRF) cavities is proceeding; re-assembly of two cavities into the horizontal testbed (HTB) will occur in approximately two weeks, with additional measurements in the Cryomodule Test Facility then following.Preparations are underway for the July 22-24 Independent Project Review by DOE. The primary focus of the preparations is ensuring that the criteria for Critical Decision 3 Approval (“Start of Construction”) are well in hand.
PhysicsIn Hall A, production running for experiment E04-007
(Pi-Zero Electroproduction near Threshold) continues to progress
smoothly. AcceleratorOverall, the accelerator is running smoothly, but it has had its bumps. Early on, a little over a shift was lost due to a vacuum problem traced to a corroded connector for a vacuum ion pump. While restoring from the vacuum problem, the Arc 1 power supply would not stay on, causing the loss of another shift. A definite cause was not found, but it is now working, and a spare supply has been procured from the Free-Electron Laser and is in place to be swapped out if needed. Seasonal ground temperature changes are causing the accelerator to grow ever so sightly as noted by the beam pathlength adjustments that are being made during almost every shift. The rest of the week and weekend were very quiet with long stretches of continuous beam delivery.
AnnouncementsJLab Spring Cleanup Week: May 5-9A weeklong, lab-wide clean up has been scheduled for the first week of May. Check with your supervisor for details. Dumpsters and forklifts will be provided. To arrange dumpsters, pick-up assistance and forklifts, contact Tom Briggs at x5430 or tbriggs@jlab.org. For excess materials questions, contact Joan Holloway at x7348 or Campbell@jlab.org. Excessing Unused JLab Property Goes Electronic All JLab property custodians now have access to an electronic excessing tool for excessing property that isn't on your property inventory list. Click on the line that reads Submit disposal/excess of property not on your inventory and complete the process. You will receive a Facilities Services Work Request email assigning a tracking number to the job. Property listed in your custodian inventory may now also be excessed electronically. Go to your Property Validation list to initiate the electronic excessing process of tagged property on your inventory list. Property custodians may access their property list from the Property page. Click on Property Validation at the bottom of the Resources listing. Reporting Theft Results in Quick Recovery of Snatched Computer The recent theft of a JLab laptop from the ARC building brings home the importance of following procedures. The laptop was stolen from a third-floor laboratory during the middle of the day earlier this month. The computer was taken by a person who entered the ARC through deception and spotted the laptop on top of a desk in an open, unoccupied lab. The loss was immediately reported, and a short time later, Newport News police apprehended an individual who had possession of the laptop in the trunk of his vehicle. For the full story, click here. Donate to Tornado Victims, Not Scam Artists If you want to assist victims of the tornado that hit Suffolk this past week, local authorities suggest that you donate cash through well-known and reputable organizations and charities. For a partial list of local charities and links to their websites, visit the We Hear That webpage. First Class Mail Rate Increase The cost of a first-class stamp will increase from 41 cents to 42 cents on May 12. Prices for other postal services will also increase. Visit the U.S. Postal Service website for more information. JLab Run-A-Round Don't forget to register to run/walk in the race and to volunteer to help make this year's event a success! Activities begin in front of CEBAF Center at 3 p.m. on Wednesday, May 14.

Environment, Safety, Health & QualitySpring is the time when people engage in cleanup
chores. Often materials that have sat in garages and basements for
extended periods of time are now "rediscovered." While most items pose
no risk, it is not uncommon for people to find items they cannot
identify or items that are in damaged containers. People also may not
know the correct way to handle or
dispose of items that may pose a risk to others or to the environment.
Here are a few things to keep in mind when going through your garage or
basement:
