Arrive a day early, Tuesday, April 11, 2017, and join us for a tour of the Advanced Photon Source (APS)! The APS is a type of ultra-bright, high energy light source known as a synchrotron that produces x-rays for material studies. At the APS, electrons are accelerated to velocities near the speed of light in a linear accelerator and then injected into the booster synchrotron. Here, the electrons are further accelerated they reach 7 GeV in energy. Upon reaching that energy, the electrons are injected into the storage ring, a 1,104-metre (3,622 ft) circumference ring of more than 1,000 electromagnets.
The Advanced Photon Source (APS), which is an Office of Science user facility funded by the U.S. Department of Energy, is one of the most technologically complex machines in the world. This premier national research facility provides the brightest high-energy X-ray beams in the West Hemisphere to more than 5,700 scientists each year from every U.S. state, the District of Columbia, Puerto Rico, and many countries around the world. These scientists come to the APS from academia, industry, medical schools, and other research institutions to carry out experiments that promise new discoveries in nearly every scientific discipline, including materials science; life science; chemistry; environmental, geological, and planetary science; and physics. The X-ray beams provided by this remarkable facility enable the collection of data in unprecedented detail and in amazingly short time frames. The knowledge these researchers gain at the APS has a real and positive impact on our technologies, our health, our economy, and our fundamental understanding of the materials that make up our world.
NNSA supports 2 sectors at APS:
The High Pressure Collaborative Access Team (HPCAT) develops and delivers leading-edge capabilities for the study of materials under extreme conditions. HPCAT operates Sector 16 of the APS where four simultaneously operational beamlines have been established with an array of high-pressure x-ray diffraction, x-ray spectroscopy, and x-ray imaging techniques. These capabilities have been successfully used to make high-fidelity measurements of crystal and amorphous structures, equations of state, phase transformations, changes in electronic properties (e.g., insulator-metal-superconductor transitions), strength and rheology, liquid states properties (e.g., structure, viscosity), and a range of other material properties at extreme P-T conditions.
The Dynamic Compression Sector (located at Sector 35 on the APS experiment hall floor), takes advantage of the high energy, tunable x-rays provided at APS to investigate material behavior using state-of-the art dynamic compression platforms (ex. gas guns and lasers). Unlike other capabilities within the NNSA complex, scientists can capture multiple images of the change in a materials crystal structure and microstructure within a single experiment under impact from a laser drive or a gas gun. This makes DCS a one of a kind experimental capability that is customized for the NNSA mission and has the potential to revolutionize material science. At DCS, there are 4 experimental end stations: Station B- Special Purpose used for unconventional experimental set-ups (ex. detonation experiments); Station C- Laser Shock Experiments houses a 100 J laser; and Stations D and E- Impact Experiments for single stage and 2 stage gas gun use.
Due to the lengthy approval process, any non-U.S. citizens need to register no later than March 27, and will need to email copies of INS documents, such as permanent resident card or passport and visa and either your DS-2019 or I-20 document, if applicable, to email@example.com.
Required tour attire: long pants and flat, closed-toe shoes; no sandals, no sleeveless shirts.
Be sure to bring your driver's license or passport.
Meet in the lobby of the Chicago Marriott Naperville on Tuesday, April 11, at 1:00 p.m. to board the bus! Only those registered will be able to attend.
Any questions, contact Terri Stone, firstname.lastname@example.org.
