Run the DOE Mile at 2018 Run-A-Round 

The race is on to register for the 2018 Run-A-Round ! This year's event will feature the DOE Mile, a 1-mile “virtual” race against other DOE Laboratories! Visit the link for more information. 

				
		
		



ACCELERATOR SCIENCE / EXPERIMENTAL NUCLEAR PHYSICS 
In Hall A, MARATHON (E12-10-103), the first of several experiments using the tritium target, is nearing completion. By comparing inclusive cross sections on the mirror nuclei helium-3 and tritium, this experiment seeks to measure d to u quark ratios. After MARATHON, beam on the tritium target will continue with a coincidence measurement (E12-13-012) that explores the nature of short-range correlations of nucleons in the nucleus. 

Hall B is currently in the early phase of the science program with CLAS12. The ongoing experimental run covers seven experiments, each with a different science focus: from the 3D imaging of the proton's internal quark and gluon structure, to the measurement of nucleon resonance transition form factors, to the search for exotic hadrons. 

Hall C has completed the "commissioning" set of experiments, measurements that exploit the capabilities of the new Super High Momentum Spectrometer and pre-existing equipment. These experiments include a measurement of proton structure at high x (E12-10-002), a search for color transparency (E12-06-108), EMC effect studies (E12-10-008) and high momentum deuteron electo-disintegration (E12-10-003). The hall is now starting the "early" 12 GeV era experiments, including transverse momentum dependence of semi-inclusive pion production (E12-09-017) and exclusive kaon production (E12-09-011). 

CENTER FOR COMPUTATIONAL AND THEORETICAL PHYSICS 
The Jefferson Lab Angular Momentum (JAM) collaboration has performed the first global QCD analysis of parton distribution functions in the pion , combining pion-nucleon Drell-Yan data with leading neutron production in electron-proton scattering, within a new Monte Carlo framework. The combined analysis reveals that gluons carry a significantly higher fraction of the pion's momentum fraction, 30 percent, than that inferred from Drell-Yan data alone, with sea quarks carrying a somewhat smaller fraction, 15 percent. Within the same effective field theory framework, the pion PDFs can be used to describe the \bar{d} - \bar{u} asymmetry in the proton and make predictions for the new SeaQuest experiment at Fermilab and the planned Tagged DIS (TDIS) program at Jefferson Lab. 

ESH&Q 
Types of Fire Extinguishers 
Fire extinguishers are classified by the types of fires they extinguish. There are five basic kinds, identified in this handy chart from OSHA and here: 
A: For wood, cloth and paper. 
B: For combustible and flammable liquids such as oil, gasoline and paint. 
C: For electrical equipment and tools. 
D: For flammable metals. 
K: For animal or vegetable oils or cooking facts. 

It's important to use the right extinguisher for the type of fire. Using the wrong extinguisher can put your life in danger and make the fire worse. For example, never use a water extinguisher on electrical fires; you could electrocute yourself and the people nearby. If you're in the slightest doubt about tackling a fire, leave it alone, evacuate and call 911. 

Fire Safety Training (SAF108) is available to lab employees who wish to become more familiar with fire safety protocols. For more information, contact Tim Minga at x7310 . 

COMPUTING 
IT Division Maintenance Period Set for April 17 , 5-8 p.m. 
The IT Division is having a maintenance period on Tuesday, April 17 , 5-8 p.m. During this time, network switches will be upgraded in the Test Lab, the LERF Bldg. and the CEBAF Center 3rd F wing. The upgrades will cause all phones, desktops and wireless access to be down for about 15 minutes per switch upgrade. The outages will start at around 5:30 p.m., and everything should be back online by 8 p.m. Updates to centrally managed CUE software, such as Firefox, will be released to all managed desktops. Finally, all Windows and Linux patches will be released to managed desktops and servers. There will be intermittent outages of central services overnight, such as webservers and login servers, while the underlying servers are rebooted to finalize patch installation. Plan on rebooting your Windows or Linux desktop by COB on Friday, April 20 , to finalize patch installations on your desktop. If you have any questions or concerns about this maintenance period, contact the TT Division Help Desk at helpdesk at jlab.org or x7155. 


GENERAL ANNOUNCEMENTS 

Volunteer Now for the 33rd Annual Run-A-Round 
Volunteer help is needed before, during and after the event to carry out a variety of tasks. Volunteers will get a free Jefferson Lab T-shirt. The most coveted positions fill up fast, so pick your favorite task and register today at the link . 

Reminder: D&I Webinar Offered Tomorrow 
Jefferson Lab’s Diversity & Inclusion Council is now offering free webinars on a variety of current workplace topics relevant to working in academic and research environments. The first webinar, “Succeeding with Difficult People: Steps 1, 2, and 3,” will be offered Thursday, April 12 in CEBAF Center room L102 at 1 p.m. Seminars vary in length from one hour to an hour and a half. No reservations are required. A schedule of seminar topics can be found in the full memo . 

2018 Open House Volunteer Registration is Open 
In an open letter sent to the Jefferson Lab community earlier today , Lab Director Stuart Henderson asked community members to volunteer their efforts toward a successful 2018 Jefferson Lab Open House Event. Visit the link to volunteer yourself, your neighbor or your family members who are 13 years of age or older. 

Reminder: LDRD Program Proposals Due April 29 
The Laboratory Directed Research and Development (LDRD) program is soliciting proposals for new projects that would begin in October 2018 (and continuation proposals from projects underway that will not be completed this year). The due date for formal proposals is April 29 . For more information, see the webpage . 

JSA Sponsors Annual Teacher Night Event 
Tonight , elementary and middle school teachers interested in learning new and innovative methods for teaching the physical sciences will converge on CEBAF Center for the Jefferson Science Associates Region II Teacher Night. Read more about the event here .
