Center for Theoretical and Computational Physics
Researchers from the Joint Physics Analysis Center have recently studied the photoproduction of a neutral pion on a proton target in the energy above the resonance region. The model, based on the leading Regge pole exchanges, describes well the existing data for beam energies above 4 GeV and provides predictions for the differential cross sections at CLAS, CLAS12 and GlueX energies. The computer codes, simulation of predictions and other relevant materials related to the model are available through the JPAC website.

Jefferson Lab Prepares for Hurricane Season
Hurricane Season is June 1 - Nov. 30. Jefferson Lab observes the season by elevating its preparedness level to Hurricane Preparedness Condition 1 (HPC-1) on June 1. Everyone at the lab has a basic preparedness responsibility: Ensuring that their work area is kept free of hazards and that housekeeping is a priority each work day. This helps us to more quickly prepare the lab for a hurricane or any other severe weather event and also gives us more time to prepare our families and homes. In addition, Hurricane Wardens have been assigned to specific areas to ensure these areas are secured prior to a hurricane.
Understanding and being prepared for a hurricane can saves lives and property and reduce injuries. The linked All-Staff Memo has important information about personal and Jefferson Lab hurricane preparedness planning. Take a moment now to review the material so that you are ready before the next big storm.
Computing and Networking Infrastructure
Central File Server Outage Set for Friday, June 26, 6-10 p.m.
There will be an outage of the /home (J: drive) file server on Friday, June 26, 6-10 p.m. During this time, this important file server will be undergoing a major operating system upgrade, and many services may be unavailable. In particular, access to all of the login servers, including login, jlabl*, publ*, and other login servers will have issues while the home directory is offline. Note that CUE (Common User Environment) level 1 Linux systems may need to be rebooted after the outage to clear up any lingering mount issues, so plan your work accordingly. If you have any comments or concerns, contact the IT Division Helpdesk, x7155.
Personal Dosimeter Change Out Set for Wednesday, July 1
Jefferson Lab's semi-annual personal dosimeter change out will take place during the afternoon of Wednesday, July 1. This includes the dosimeters of all staff, students, users and subcontractors. Be sure to put your dosimeter in its assigned place in the dosimeter racks no later than 2 p.m. on July 1. If you need to use your dosimeter during the change out period on July 1, you may exchange it that morning in the Radiation Control Dosimetry Office located in the ARC Library between 8 a.m.-1 p.m. If you are leaving for an extended Independence Day holiday break, be sure to put your dosimeter in its assigned rack before departing. If you have any questions about the change out, contact Becky Mosbrucker, x7236.
Graduate Students Sought for Tour Program
The Public Affairs office is seeking graduate students who are interested in working as tour escorts during lab tours. In addition to learning about other areas of the lab, meeting new people and practicing your public speaking skills, students can receive payment for assisting as tour escorts and/or tour subject matter speakers. For more information about this program, see the All-Staff Memo or contact Mike Robbins, x7617.
LabVIEW User Group: Using Ladder Logic in LabVIEW
Do you ever wish CompactRIO could be programmed or maintained with Ladder Logic? Learn about a new NILabs offering on the NI Linux RT based CompactRIO allowing the LabVIEW system designer the option to deploy ladder logic (or other IEC 61131 languages) applications on the NI platform. A one-hour information session will be held on Wednesday, June 24 at noon in CEBAF Center conference room F224/225. The event is open to all members of the Jefferson Lab community. Questions about LabVIEW may be directed to Christiana Grenoble, x5850.
Jefferson Lab T-shirts Available for Purchase on June 18
JAG is expecting the second shipment of Jefferson Lab 2015 T-shirts to be available for purchase on Thursday, June 18. They will be available on a first-come, first-served basis at the CEBAF Center reception desk, Monday – Friday, 8 a.m.-5 p.m. Cash or a check, made payable to "Jefferson Lab," will be accepted. The cost of the short-sleeve T-shirt is $7. Those who ordered "special order items" (hoodies and long-sleeve T-shirts) will be able to pay for and pick these up on Thursday and Friday, June 18 and 19, 11:30 a.m.-1:30 p.m. at a table in the CEBAF Center lobby. JAG will email the individuals who placed "special orders." If you need to make alternate arrangements for pickup, contact Mary Jo Bailey at x7277.
Annual Fraud Awareness Briefing Offered July 1
Mike Adams, DOE Office of Inspector General, will visit Jefferson Lab on July 1 to give the annual Fraud Awareness briefing. The briefing is set for 10 a.m. in the CEBAF Center auditorium. The meeting is open to all members of the lab community.
