12 GeV Upgrade
The concrete shield house and support platform for the Hall C Super High Momentum Spectrometer are being outfitted with electrical, cryogenic and water services in anticipation of arrival of the first of the new superconducting magnets. All the new high-current power supplies have been tested using the magnets of the High Momentum Spectrometer as high-inductance loads. Construction of two of the magnets, the HB dipole and Q1 quadrupole, is now in the latter stages. The thermal shield and cryostat have been added to the Q1 magnet, and sensor and instrumentation work continues in preparation for the cryogenics control reservoir. Addition of the several dozen parts of the thermal shield is underway for the HB magnet, after which the cryostat can be attached. The first production coil for the SHMS dipole magnet is having its last layer wound, and the second production coil has reached the mid-point of its winding. The tooling is on order to fabricate the Q2 and Q3 magnets, with winding planned to begin in September.
Center for Theoretical and Computational Physics
A new paper presents a method for extracting one-to-two form factors from lattice QCD. This formalism is relevant for rare heavy meson decays, such as B0 → π K l+ l-, as well as meson photoproduction (π γ → π π). Our result, derived using relativistic field theory, describes systems with any number of two-particle channels and accommodates arbitrary partial waves.
Jefferson Lab Calendar of Events
July 4: Independence Day holiday - Jefferson Lab closed
Environment, Safety, Health and Quality
No Smoking Allowed in Buildings
Computing and Networking Infrastructure
To assist with an easy migration, there will be training sessions held on July 10 and July 23 at 2 p.m. in CEBAF Center room F113. ReadyTalk was mainly used for audio conferencing, therefore, audio conferencing will be the focus of these training sessions. There will be time at the end of each session for all questions regarding BlueJeans (H.323, web conferencing, etc.). To learn more, visit the BlueJeans webpage for information on logging in and configuring BlueJeans with your Jefferson Lab computer account.
Last Chance to Renew Your SmartCard
To avoid problems and delays, be sure to have your card renewed before July 11. Once the expiration date passes, the card will no longer work, and the user will not be able to log in to Jefferson Lab systems using the card. If you have any questions or concerns, contact the IT Division Helpdesk, x7155.
