Hall D Update
The first physics run of the GlueX experiment is progressing in Hall D, as planned. About 50 billion events have been recorded so far. During the remaining two weeks of beam, it is expected to accumulate more data as well as perform various specialized measurements needed for the GlueX physics program. -

The Torus magnet for CLAS12 was brought back down to liquid helium temperature at the end of January to prepare for the CLAS12 Key Performance Parameter beam commissioning run reported recently. The magnet operated without incident for the entire run. It was then kept at 4 Kelvin for two weeks to gain operational experience with the cryogenics and make incremental improvements to the control loops. -

January 12, 201712 GeV Upgrade
The Torus magnet for CLAS12 has been parked at a temperature of 80 Kelvin for the past two months awaiting the upcoming beam run in Hall B. t will be brought back down to liquid helium temperature at the end of January to prepare for the run. The drift chambers have all been suspended from the Torus cryostat and had their services attached, and the Forward Carriage has been rolled upstream to its operating position next to the Torus.
