12 GeV Upgrade

The Solenoid magnet was delivered to Hall B on Tuesday, June 27, after a 10-hour road-trip from the vendor in Pennsylvania. The magnet was parked in Hall B overnight. Following unloading and initial receipt inspections on the morning of June 28, the magnet was placed on the CLAS12 spectrometer carriage. The Solenoid magnet is the last component of the 12 GeV Upgrade Project.

History Archives Photo of the Week
This week's photo of the week features exhibit items at CEBAF's annual art festival, 1991. Our bonus photo is from the May 2000 art festival, featuring Barbara Adams, wife of the late Greg Adams, and their son Gregory. Young Gregory won a ribbon during the festival for a series of digital photos he took when he was two years old.

Center for Theoretical and Computational Physics

A new method has been proposed to extract parton distribution functions (PDFs) from lattice QCD calculations. The method is based on the concept of pseudo-PDFs and their relation to transverse momentum distributions (TMDs). The lattice data demonstrate factorization for TMDs, and, at short distances, follow the scale-evolution equations as required from perturbative QCD.

Hogan Drive Traffic Pattern Changes To Begin Thursday, June 29
The basecoat of asphalt has started on the newly constructed north outbound lanes on Hogan Drive, which are located on the apartment side of the road. Once this basecoat is complete, the contractor will need to initiate a series of “Traffic Pattern Changes” to construct turn lanes into the apartments, apply the finish coat of asphalt and stripe the roads. Weather pending, the contractor plans to implement the first lane change on Thursday, June 29.

The contractor will provide road signage indicating the new traffic patterns, so that you will be able to understand the changes when entering, navigating through and leaving Hogan Drive. Pay attention to these traffic pattern changes and use extreme caution during these final construction activities, which are expected to be complete in early to mid-August.

If you have any questions or concerns about this work, contact Bob Sperlazza at 269-6241.

Personal Dosimeter Changeout Set for Wednesday, July 5
Jefferson Lab's semi-annual personal dosimeter changeout will begin at 1 p.m. on Wednesday, July 5. This includes the dosimeters of all lab staff, Users, subcontractors and students. If you will be away from the lab on vacation or travel, be sure to put your dosimeter in its place in the rack before you depart the lab. If you won't be using your dosimeter during the changeout period, place it in its assigned place in the dosimetry racks for the changeout. As always, make sure your dosimeter is in its assigned rack at the end of your work day. If you need to use your dosimeter during the changeout period on July 5, you may exchange it that morning in the Radiation Control Dosimetry Office in the new ESH&Q Building, Bldg. 52,  8 a.m.-noon. If you have questions, contact Becky Mosbrucker, x7236.
