Helical Orbit Spectrometer
The helical orbit spectrometer (HELIOS) is a measurement device for studying nuclear reactions in inverse kinematics. It is installed at the ATLAS facility at Argonne National Laboratory. History The HELIOS concept was first proposed at the ''Workshop on Experimental Equipment for an Advanced ISOL Facility'' at Lawrence Berkeley National Laboratory in 1998. The concept was introduced as a next-generation large-acceptance spectrometer for measuring heavy ion reactions. Concept Schematically, HELIOS is based around a large-bore superconducting solenoid. Accelerated heavy-ion beams enter the solenoid along the magnetic axis, passing through a hollow detector array. The beam then intercepts a "light-ion" target, also on the magnetic axis. In the configuration shown in the figure, charged reaction products ejected rearward in the laboratory frame move in helical orbits to the detector array. Heavy beam-like recoils are kinematically focused forward in a narrow cone and intercepted ...

HELIOS Side View
In ancient Greek religion and Greek mythology, mythology, Helios (; ; Homeric Greek: ) is the god who personification, personifies the Sun. His name is also Latinized as Helius, and he is often given the epithets Hyperion ("the one above") and Phaethon ("the shining"). Helios is often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol (Roman mythology), Sol. The Roman Emperor Julian (emperor), Julian made Helios the central divinity of his short-lived revival of Religion in ancient Rome, traditional Roman religious practices in the 4th century AD. Helios figures prominently in several works of Greek mythology, poetry, and literature, in which he is often described ...

Nuclear Reactions
In nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides. Thus, a nuclear reaction must cause a transformation of at least one nuclide to another. If a nucleus interacts with another nucleus or particle, they then separate without changing the nature of any nuclide, the process is simply referred to as a type of nuclear scattering, rather than a nuclear reaction. In principle, a reaction can involve more than two particles colliding, but because the probability of three or more nuclei to meet at the same time at the same place is much less than for two nuclei, such an event is exceptionally rare (see triple alpha process for an example very close to a three-body nuclear reaction). The term "nuclear reaction" may refer either to a change in a nuclide induced by collision with another particle or to a spontaneous change of a nuclide without collisio ...

Argonne Tandem Linear Accelerator System
The Argonne Tandem Linac Accelerator System (ATLAS) is a U.S. Department of Energy scientific user facility at Argonne National Laboratory. ATLAS is the first superconducting linear accelerator (linac) for heavy ions at energies in the vicinity of the Coulomb barrier and is open to scientists from all over the world. The ATLAS accelerator at Argonne should not be confused with the ATLAS experiment at the Large Hadron Collider at CERN. Properties Stable ion beams at ATLAS are generated from one of two sources: the 9-MV electrostatic tandem Van de Graaff accelerator or the Positive Ion Injector, a 12-MV low-velocity linac and electron cyclotron resonance (ECR) ion source. The ions are sent from one of these two into the 20-MV 'booster' linac, then to the 20-MV 'ATLAS' linac section. The ATLAS linac is constructed with seven different superconducting resonator designs, each one creating an electromagnetic wave of a different velocity. The ions in the ATLAS linac are aligned i ...

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 Midwestern United States, 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 ...

Canadian Penning Trap Mass Spectrometer
The Canadian Penning Trap Mass Spectrometer (CPT) is one of the major pieces of experimental equipment that is installed on the ATLAS superconducting heavy-ion linac facility at the Physics Division of the Argonne National Laboratory. It was developed and operated by physicist Guy Savard and a collaboration of other scientists at Argonne, the University of Manitoba, McGill University, Texas A&M University and the State University of New York. Development The CPT was originally built for the Tandem Accelerator Superconducting Cyclotron (TASCC) facility at Chalk River Laboratories in Chalk River, Ontario, Canada. However, it was transferred to Argonne National Laboratory when the TASCC accelerator was decommissioned in 1998 due to funding issues. The CPT spectrometer is designed to provide high-precision mass measurements of short-lived isotopes using radio-frequency (RF) fields. Accurate mass measurements of particular isotopes such as selenium-68 are important in the understandi ...

Gammasphere
The Gammasphere is a third generation gamma ray spectrometer used to study rare and exotic nuclear physics. It consists of 110 Compton-suppressed large volume, high-purity germanium detectors arranged in a spherical shell. Gammasphere has been used to perform a variety of experiments in nuclear physics. Most experiments involve using heavy ion nuclear fusion to form a highly excited atomic nucleus. This nucleus may then emit protons, neutrons, or alpha particles followed by a shower of tens of gamma rays. Gammasphere is used to measure properties of these gamma-rays for tens of millions of such gamma ray showers. The resultant data are analyzed to gain a deeper understanding of the properties of nuclei. Gammasphere was built in the early 1990s and has operated at the 88-inch cyclotron at Berkeley National Laboratory and at Argonne National Laboratory. In the movie ''Hulk'', Bruce Banner is zapped by a machine called the Gammasphere. The actual Gammasphere, which detects rather ...
