Argonne Tandem Linear Accelerator System

Argonne National Laboratory is a federally funded research and development center in Lemont, Illinois, United States. Founded in 1946, the laboratory is owned by the United States Department of Energy and administered by UChicago Argonne LLC of the University of Chicago. The facility is the largest national laboratory in the Midwest. Argonne had its beginnings in the Metallurgical Laboratory of the University of Chicago, formed in part to carry out Enrico Fermi's work on nuclear reactors for the Manhattan Project during World War II. After the war, it was designated as the first national laboratory in the United States on July 1, 1946. In its first decades, the laboratory was a hub for peaceful use of nuclear physics; nearly all operating commercial nuclear power plants around the world have roots in Argonne research. More than 1,000 scientists conduct research at the laboratory, in the fields of energy storage and renewable energy; fundamental research in physics, chemistry, and materials science; environmental sustainability; supercomputing; and national security. Argonne formerly ran a smaller facility called Argonne National Laboratory-West (or simply Argonne-West) in Idaho next to the Idaho National Engineering and Environmental Laboratory. In 2005, the two Idaho-based laboratories merged to become the Idaho National Laboratory.Argonne is a part of the expanding Illinois Technology and Research Corridor.

Chicago Pile-5 (CP-5) was the last of the line of Chicago Pile research reactors which started with CP-1 in 1942. The first reactor built on the Argonne National Laboratory campus in DuPage county, it operated from 1954-1979.CP-5 was a thermal-neutron reactor using enriched uranium as fuel and heavy water as coolant and as a neutron moderator. It produced neutrons for use in research. The reactor had an output rating of 5 megawatts.Cleanup and decommissioning of the site of CP-5 was started in 1991 completed in 2000. The cleanup process included removal of all contaminated equipment and spent fuel, decontamination of the reactor vessel and associated plumbing, and removal of the spent fuel pool, reactor internals and the hot cell liner. The accessible areas of the structure have been certified as having radiation levels equivalent to background radiation.

Now the NBL Program Office, the New Brunswick Laboratory (NBL), was a United States government-owned and operated, center of excellence in the measurement science of nuclear materials. It was established in 1949 by the Atomic Energy Commission and was located in New Brunswick, New Jersey. It was relocated between 1975 and 1977 and was located, as a Federal enclave, on the site of Argonne National Laboratory, about 40 kilometers (25 miles) southwest of Chicago, Illinois. NBL was part the Department of Energy's Office of Science Chicago Office.NBL is the U.S. Government's Nuclear Materials Measurements and Reference Materials Laboratory and the National Certifying Authority for nuclear reference materials and measurement calibration standards. As an internationally recognized Federal laboratory, NBL provides reference materials, measurement and interlaboratory measurement evaluation services, and technical expertise for evaluating measurement methods and safeguards measures in use at other facilities for a variety of Federal program sponsors and customers. NBL functions as a Network Laboratory for the International Atomic Energy Agency (IAEA). NBL was reorganized into the NBL Program Office in 2016, and its nuclear reference materials were transferred to a new distribution center located near Oak Ridge, Tennessee. It is part of the National Nuclear Security Administration's Office of Defense Programs.

The Advanced Photon Source (APS) at Argonne National Laboratory (in Lemont, Illinois) is a storage-ring-based high-energy X-ray light source facility. It is one of five X-ray light sources owned and funded by the U.S. Department of Energy Office of Science. The APS began operation on March 26, 1995. It is operated as a user facility, meaning that it is open to the world’s scientific community, and more than 5,500 researchers make use of its resources each year.

Waterfall Glen is a forest preserve in Downers Grove Township, DuPage County, Illinois, between the towns of Darien and Lemont, covering 2,492 acres (1,008 ha). It contains several waterfalls on Sawmill Creek as it empties into the Des Plaines River. Rocky Glen Falls, the largest waterfall in the preserve, is actually a natural dam in the valley glen. In the 1930s, the Civilian Conservation Corps helped restore the waterfall to its naturally tiered state, after years of erosion due to runoff from a nearby mill. It completely surrounds Argonne National Laboratory. It is also home to a popular model airplane field, located in the southwest section of the forest preserve. Hikers can also make the interior trip to St. Patrick Cemetery nestled deep in the preserve. Waterfall Glen's tallgrass prairies, bogs, and Midwestern oak savannas contain 740 native plant species, 75 percent of all the plants known to grow naturally in DuPage County. Over 300 species of mammals, birds, fish, amphibians, and reptiles and another 300 species of invertebrates use the forest preserve, either year-round or during their migrations.

The National Shrine & Museum of St. Therese in Darien, Illinois is a Roman Catholic shrine dedicated to St. Thérèse of the Child Jesus and the Holy Face. The Shrine is a part of the Aylesford Carmelite campus, run by the Carmelite Order, Province of the Most Pure Heart of Mary. The National Shrine & Museum of St. Therese is supported and served by the Society of the Little Flower, a religious organization dedicated to promoting devotion to St. Therese of Lisieux .

The Track Imaging Cherenkov Experiment (TrICE) is a ground-based cosmic ray telescope located at Argonne National Laboratory near Chicago, IL. The telescope, which contains a Fresnel lens, eight spherical mirrors, and a camera with 16 multianode photomultiplier tubes, uses the atmospheric Cherenkov imaging technique to detect Cherenkov radiation produced when cosmic rays interact with particles in the Earth's atmosphere. The telescope is primarily a research and development tool for improving photomultiplier tube cameras and electronic systems for future gamma and cosmic ray telescopes. It is also used to study the energy and composition of cosmic rays in the TeV–PeV range, and the collaboration is currently conducting pioneering work in detecting direct Cherenkov signals from cosmic rays.

Tedens is a ghost town in Downers Grove Township, DuPage County, Illinois, United States.

Darien (formerly Cass) is a city in DuPage County, Illinois, United States. Per the 2020 census, the population was 22,011. A southwestern suburb of Chicago, Darien was named after the town of Darien, Connecticut. Darien is just north of I-55 and Historic U.S. Route 66 (now Frontage Road). The entire south edge of the town borders Waterfall Glen.

Center Cass School District 66 is a public school district located in Downers Grove, Illinois, in DuPage County. The district serves about 1,300 students in grades K-8. Center Cass District 66 currently consists of Elizabeth Ide School (grades K-2), Prairieview Elementary School (grades 3-5) and Lakeview Jr. High School (grades 6-8). These elementary and junior high schools each feed into Downers Grove South High School (Community High School District 99).

The Hindu Temple of Greater Chicago (HTGC) is a Hindu temple complex in Lemont, Illinois. It was inaugurated and opened to the public in 1986. It includes a Rama temple and a temple dedicated to Ganesha, Shiva, and Durga.

The Forge: Lemont Quarries Adventure Park is an adventure park that opened July 17, 2020 in Lemont, Illinois, a suburb of Chicago. It is a public-private partnership with the Village of Lemont and Lemont Township.Covering approximately 300 acres (120 ha), it features ziplines, ropes courses, climbing towers and walls, bouldering areas, fishing, paddleboating, kayaking, mountain biking and hiking trails and other outdoor activities. The ropes course will be the tallest in North America, at over 120 ft (37 m). It also has adventure dining, a beer garden, an event venue, and summer camps.The park was built on disused industrial land and flooded former Lemont yellow dolomite quarries straddling the Illinois and Michigan Canal National Heritage Area, and abutting the Chicago Sanitary and Ship Canal. It is named after the Forge Quarry and uses it, the Great Lakes Quarries, and the I&M Canal as water features. It was originally scheduled to open on May 25, with a grand opening scheduled for June 27, 2020, but due to the COVID-19 pandemic this was pushed back to July 2020.
