T2K Neutrino Beam Line
Jul 17, 2008
T2K (Tokai to Kamioka) neutrino beam line nears completion. Built inside the 50 GeV synchrotron, 28 multifunctional quad-dipole superconducting magnets will bend proton beams toward toward Super-Kamiokande, 300 km away neutrino detector.

K2K Near Detector
Feb, 1999
Consisting of a 1kton water Cerenkov detector and a fine-grained detector for Long-baseline Neutrino Oscillation Experiment. The near detector system is located at 300m downstream of the KEK PS beamline production target.

BESS
BESS collaboration launches a 130 m wide balloon in Alberta, Canada. Once launched, a 2.3 ton detector is airborne for about 24 hours at an altitude of 37 km in the stratosphere, in search of anti-nucleus in the cosmic ray. If any abundances of anti-helium flux were to be found in the data, it might indicate the existence of "anti-matter galaxy". Researchers from KEK has built a compact and light weight superconducting solenoid for the detector.

BESS
Dec 13, 2004
BESS-Polar instrument, launched successfully on December 13 from McMurdo Station, Antarctica, beneath a 40-million-cubic-foot scientific balloon, as big as a football field. To maximize the possibility of finding the antimatter predicted by Hawking, the team is hoping for at least a 10-day flight, or once around the South Pole, in a near-space environment above 99% of the atmosphere. The instrument is circling the Pole at an average altitude of 24 miles (39 kilometers).
BESS-Polar is collaboration among scientists at KEK, the University of Tokyo, Kobe University, and the Institute of Space and Astronautical Science of the Japan Aerospace Exploration Agency, along with NASA and the University of Maryland, College Park. BESS stands for Balloon-borne Experiment with a Superconducting Spectrometer.
