| 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) |
 |
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 |
 |
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
|
 |
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. |

& Atomic Force Microscopy |
 |
The
Nanophysics Cluster Research Group
at the University of Hawaii is involved
in research that centers around the
data provided by the excellent array
of ultra-high resolution microscopes
available in the lab. These include
a state-of-the-art Atomic Force Microscope,
and a scanning-tunneling electron
microscope, both of which produce
stunning images of atomic surface
structures, and engender a variety
of exciting solid-state research topics. |

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 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.

| Neutrino
Astrophysics: Super Kamiokande (Super K) |
 |
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. |

| Neutrino
Physics: K2K (KEK to Kamioka) |
 |
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 |
 |
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. |
