Brene Brown - Dare to Lead

Brene Brown talks about how we can become "Braver" Leaders

DEI Keynote 10.19.21 - Working Towards Making Equity Visible for Employees with Disabilities

Veleka Gatling, Ph.D., Director of Diversity at ODU, shared a presentation on how we can achieve visible equity for our employees with disabilities ultimately by treating them as they desire, not as we desire.  We must listen to other’s stories and begin shifting our cultural perspectives to achieve acceptance and adaptation ultimately operationalizing inclusion.  She encouraged all of us to be “Braver” Leaders by rumbling with vulnerability, living our values, building trust and learning to rise and reset.  She also introduced four tenets to build a framework for interventions that

Jefferson Lab is home to the world's most powerful tunable Free-Electron Laser.  

Jefferson Lab is home to the world's most powerful tunable Free-Electron Laser.  The FEL uses the same superconducting radiofrequency technology as Jefferson Lab's CEBAF accelerator. The FEL has been used to conduct an extensive range of applied and basic research.Unique to the FEL is the range of light it can produce. This tunability allows scientists to test multiple wavelengths of light. Another innovation that makes Jefferson Lab's FEL unique is its use of the energy-recovery linac, which allows the FEL to recycle energy from its electrons.

The new experimental Hall D will use the electron beam to produce a coherent bremsstrahlung beam and house a solenoid detector to carry out a program in gluonic spectroscopy to experimentally test current understanding of quark confinement.

The 12 GeV Upgrade is highly cost effective due to existing features of the Continuous Electron Beam Accelerator Facility (CEBAF). The superconducting radiofrequency linear accelerators contain superconducting niobium cavities operating, on average, at 50 percent above their design specifications in accelerating gradient and Q. The success of this technology opens up the possibility of a relatively simple, inexpensive upgrade of CEBAF's top energy.

Hall C is 150 feet in diameter and 60 feet tall.

Hall C is 150 feet in diameter and 60 feet tall. Hall C houses a High Momentum Spectrometer and has been used extensively for large-installation experiments. These are stand-alone experiments requiring unique or highly specialized detectors, magnets and targeting systems. Experiments run in Hall C have covered a broad spectrum of topics, including the structure of pions, kaon particle production, excited states of the proton, and duality.

It is equipped with the CEBAF Large Acceptance Spectrometer, or CLAS, which is shaped like an elongated sphere.

Hall B is the smallest of Jefferson Lab's three experimental halls. It is 98 feet in diameter and 65 feet from floor to ceiling. It is equipped with the CEBAF Large Acceptance Spectrometer, or CLAS, which is shaped like an elongated sphere. Experiments in this hall can receive electron beam or a photon beam. A major research program in Hall B has been the investigation of the quark-gluon structure of protons and neutrons and a detailed study of excited states.

Hall A is the largest of Jefferson Lab's three experimental halls.

Hall A is the largest of Jefferson Lab's three experimental halls. It is 174 feet across and 80 feet tall from floor to ceiling. Hall A is outfitted with two primary detector systems – both high-resolution spectrometers and each weighing about 450 tons. The systems act like huge microscopes, allowing scientists to "see" inside an atom. Hall A is used primarily for experiments that study the structure of nuclei, and of protons and neutrons.
