Jefferson Lab (JLab)
Jefferson Lab (otherwise known as the Thomas Jefferson National Accelerator Facility) is a national laboratory located in Newport News, Virginia, USA. Funded by the U.S. Department of Energy, the scientists working at JLab focus primarily on investigating the structure of the nucleus of atoms. The facility is currently undergoing an upgrade on it's Continuous Electron Beam Accelerator Facility (CEBAF), increasing it's energy from a 6 GeV beam to a 12 GeV beam. Armed with this new tool, JLab scientists hope to probe the nucleons of an atom and discover what gives them their properties, how they're held together, and so on.
Jefferson Lab has been recognized as a world leader in the field of accelerator science. CEBAF is the most advanced particle accelerator in the world for investigating the the structure of atomic nuclei. CEBAF is based on superconducting radiofrequency (SRF) technology, which the lab developed in order to support CEBAF, the first large scale use of SRF technologies in the USA. JLab is a world leader in SRF technologies today, and this experience and expertise allowed them to develop further tools, such as the Free Electron Laser.
Jefferson Lab has three halls currently in operation (Hall A, Hall B and Hall C), with a fourth hall (Hall D) under construction and expected to begin experiments as soon as 2015. With several experimental halls to work with, JLab is able to conduct several different experiments simultaneously, all with one electron beam (the beam gets split into three separate beams after being accelerated to the appropriate energy).
Dr. Sarty works with Hall A, investigating the structure of nucleons. For more detailed information of Dr. Sarty's work with JLab, look here.
Institute of Nuclear Physics, Johannes Gutenberg-University Mainz (Mainz/MAMI)
Located in Mainz, Germany, the Institute of Nuclear Physics of the Johannes Gutenberg-University Mainz (known as MAMI, after it's accelerator) focuses it's research on hadrons (a family of particles in which neutrons and protons, some of the most familiar subatomic particles, belong to). Scientists at MAMI are studying the structure and properties of hadrons in order to further our understanding of them, filling in gaps in our knowledge.
Research at MAMI takes place at relatively low energies, energies below or equivalent to the mass equivalent of the hadrons. The goal is to further our understanding of interactions at lower energies. The accelerator facility, the Mainz Microton MAMI, operates at energies of up to 1.5 GeV. It is a continuous wave accelerator, meaning that it produces a very smooth, virtually continuous beam. It's so smooth that the detectors see it as a continuous flow, allowing the experimental data to be distributed rather than concentrated in small bunches. The beam is well suited for high precision experiments investigating the structure of hydrons.
Dr. Sarty is investigating the structure and properties of protons at low energies.
