Alpha Magnetic Spectrometer (AMS-02)

The Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle detector that measures particles with energies from hundreds of MeV to a few TeV. AMS-02 was installed onboard the International Space Station (ISS) on May 19, 2011 where it will continue operate for the duration of the station, currently extended to 2024. Through the study of high energy cosmic rays (CR), AMS-02 strives to answer fundamental questions about the Universe. The primary science goals of AMS-02 are: the indirect detection of Dark Matter, a search for antimatter that will address the matter/antimatter asymmetry problem, the detection of new forms of matter such as Strangelets, precision CR measurements that answer questions about the propagation of CRs in the galaxy, and the study of short and long timescale solar activity.

Free Electron Laser Research (FEL)

The Mark III free-electron laser (FEL) as it was originally commissioned at Stanford in 1984. Research with this FEL and its subsequent configuration as an FEL master-oscillator power-amplifier is presently underway at the UH Manoa campus for remote sensing applications and advanced FEL concepts.

Terahertz Free-Electron Laser (THz FEL)

FEL The goal of the Terahertz Free-Electron Laser group is to produce high average-power, long pulse Free Electron Laser (FEL) laser light in the spectral region form 0.1 to 30 Terahertz.Applications of Terahertz laser light include Condensed Matter research, Doppler Lidar for space applications, and Power Beaming.

High Energy Physics - BELLE
FEL The goal of the BELLE experiment is the observation of CP violation in the decays of the B mesons. The experiment operates at the KEKB accelerator, a high luminosity asymmetric energy e+ e- machine.

High Energy Physics - BES
BES The BES (Beijing Electron Spectrometer ) detector, located at the Bejing Electron Positron Collider (BEPC) at the Institute of High Energy Physics (IHEP) in Beijing, records information from electron positron interactions in the tau-charm energy region from 3 - 5 GeV. This region provides rich and unique opportunities for studies of Tau leptons, D mesons, J/psi, and psi prime events.

NanoScience The nanophysics research group at the University of Hawaii concentrates on synthesis and fundamental studies of nanomaterials. The interests include the utilization of hydrothermal processing for the controlled production of advanced nanocarbons. Carbon nanofoams, graphene quantum dots and three-dimensional graphene scaffolds are studied experimentally and theoretically. Quantum computations are performed on various types of graphene nanoflakes and aromatic geodesic arene networks. Equilibrium structures, energetic stabilities and electronic structures, electric dipole-moments, and other characteristic properties are determined. The studies help to lay the foundation for future applications of nanocarbons in novel electronic, photonic and biomedical devices.

Particle Astrophysics
Particle Astrophysics The Particle Astrophysics group at the University of Hawaii studies neutrinos and high-energy galactic cosmic rays. The group is active in efforts to measure solar neutrinos collaborating on the Super Kamiokande and KamLAND detectors. It is also developing techniques and experiments for the detection of ultra-high energy neutrinos and cosmic rays by the use of radio detection. Experiments to detect radio emissions from neutrino interactions in salt (SALSA), ice (ANITA) and from the lunar surface (GLUE) are all being worked on by the group.

Particle Theory
  The interests of the Particle Theory Group include neutrino physics, CP violation, heavy quark systems, precision calculations in quantum field theory, supersymmetry, grand unification, implications of extra spatial dimensions, other physics beyond the Standard Model, and implications of particle physics for cosmology and astrophysics.

Neutrino Astrophysics: ANITA (Antarctic Impulsive Transient Antenna)
ANITA ANITA is a balloon-born cosmic-ray neutrino detector designed to search for radio pulses caused by the interactions of ultra-high energy cosmic-ray neutrinos in the Antarctic ice. These neutrinos have energies over 8 times greater in magnitude than what the largest particle accelerators on earth can achieve. A prototype of the ANITA instrument ANITA-LITE was flown in December of 2003 with a full version of the instrument was launched in December 2006.

Long-Baseline Neutrino Experiment (LBNE)
LBNE LBNE has been developed to provide a unique and compelling program for the exploration of key questions at the forefront of particle physics. Chief among the discovery opportunities are observation of CP symmetry violation in neutrino mixing, resolution of the neutrino mass hierarchy as well as interactions with matter, searches for nucleon decay signatures, and detailed studies of neutrino bursts from galactic supernovae. As an extensively-developed world-class experimental program, its relevance, importance, and probability of unearthing critical and exciting physics has only increased with time.

Neutrino Astrophysics: Super Kamiokande (Super K)
SuperK The 50,000 ton water Cherenkov detector buried deep beneath the Japanese alps has produced the first convincing evidence for atmospheric neutrino oscillations and thus mass, and has produced the most cited paper ever in experimental particle physics. The instrument is also used to study solar neutrinos and to search for nucleon decay, supernovae, and a variety of astrophysical neutrinos and unusual sources and particles, such as monopoles, WIMPS, etc. The detector has operated since 1996, will restart operations after a one year hiatus (due to PMT implosion in 11/01) in late 2002, and is expected to run for about another ten years.

mtc The miniTimeCube (mTC) is a novel compact multipurpose detector of elementary particles, aiming to detect not only neutrinos but also fast/thermal neutrons. Potential applications include the counterproliferation of nuclear materials and the investigation of antineutrino short-baseline effects. The mTC is a plastic 0.2% 10B-doped scintillator (13 cm)^3 cube surrounded by 24 Micro-Channel Plate (MCP) photon detectors, each with an 8x8 anode totaling 1536 individual channels/pixels viewing the scintillator. It uses custom-made electronics modules which mount on top of the MCPs, making our detector compact and able to both distinguish different types of events and reject noise in real time. The detector is currently deployed and being tested at the National Institute of Standards and Technology Center for Neutron Research nuclear reactor (20 MWth) in Gaithersburg MD. A shield for further tests is being constructed, and calibration and upgrades are ongoing. The mTC's improved spatiotemporal resolution will allow for determination of incident particle directions beyond previous capabilities.

Neutrino Physics: K2K (KEK to Kamioka)
K2K K2K, which stands for "KEK to Kamioka", is a so-called "Long baseline neutrino oscillation" experiment. A neutrino beam generated at KEK is observed
250 km away in Kamioka, confirming oscillations.

Neutrino Physics & Astrophysics KamLAND
FEL Data taking began with KamLAND, a 1000 ton liquid scintillation detector located about 200 m from SuperK, in January 2002. Electron anti-neutrino events are recorded from nuclear power reactors around Japan. In December 2002 KamLAND reported the disappearance of electron anti-neutrinos, consistent with the Large Mixing Angle solution to the solar neutrino problem. KamLAND also reported the first measurements of total earth radioactivity. Continuing studies will search for other rare processes, and make measurements of solar neutrinos.
