• 2016 Open House

    Staff Scientist Mark Ito talks with a group of visitors in the Hall D counting house during the open house on April 30. He briefly explained the scientific purpose of the hall to visitors, before they went into the hall. For more information and photos, click here.

    The open house attracted 12,000 visitors – the highest ever for this event.

  • Undergrad Women in Physics Tour Lab

    Nearly 150 college students representing 35 colleges and universities from Virginia; North Carolina; Maryland; Washington, D.C.; Delaware and New Jersey participated in a Conferences for Undergraduate Women in Physics event co-hosted by Jefferson Lab and Old Dominion University. On Jan. 16 the group toured Jefferson Lab facilities.

    Ken Surles-Law, Accelerator Operations, discusses running the Continuous Electron Beam Accelerator Facility with a group of conference attendees touring the CEBAF accelerator.

  • Detector Installation Continues

    The new CEBAF Large Acceptance (CLAS) detector is taking shape in Experimental Hall B. Here, the CLAS12 torus magnet central hub (silver hexagonal pipe system) is installed, along with the red-and-black Forward Time-of-Flight detectors. This layer of detectors will measure the time of arrival of the particles produced in experiments, allowing physicists to identify them.

    Behind the Time-of-Flight detector, two calorimeter modules are mounted that together will be used to identify electrons, photons and neutrons.

  • Accelerator Delivers its First 12 GeV Electrons

    The CEBAF accelerator delivered full-energy electrons on Dec. 14 as part of commissioning activities for the ongoing 12 GeV Upgrade project. Operators of the Continuous Electron Beam Accelerator Facility delivered the first batch of 12 GeV electrons (12.065 Giga electron Volts) to its newest experimental hall complex, Hall D.

  • GlueX Detector

    An overhead view of Hall D, the newest experimental hall at Jefferson Lab, and part of the 12 GeV Upgrade project. On Dec. 14, operators of the Continuous Electron Beam Accelerator Facility (CEBAF) delivered 12 GeV electrons (12.065 Giga electron Volts) to the Hall D complex. Critical to the detector system is the superconducting solenoid magnet – the large red and green equipment is the solenoid.

    The detector system will be used by the GlueX physics collaboration.
