The Extreme Universe Space Observatory onboard the Japanese Experiment Module is an international mission devoted to the detection of ultra high‐energy cosmic particles with energies E>7×1019 eV. They are revealed through emission in the atmospher

Recent progress is described in the research and development of an inertial‐electrostatic confinement fusion (IECF) device. Use of a water‐cooling jacket with non‐uniform thickness shows promising success for landmine detection application, suc

A 5‐year task is described on the research and development of the advanced humanitarian landmine detection system by using a compact discharge‐type fusion neutron source called IECF (Inertial‐Electrostatic Confinement Fusion) device and 3 dual

A cosmic acceleration mechanism is introduced which is based on the wakefields excited by the Alfven shocks in a relativistically flowing plasma. We show that there exists a threshold condition for transparency below which the accelerating particle i

This paper proposes a new concept for generating controlled, high-flux pulses of neutrinos. Laser-induced generation of relativistic protons, followed by meson production and decay, provides the neutrino source. By conservative estimate, the source w

The International Space Station (ISS) will revolutionize scientific experimentation by providing a platform upon which some of the most ambitious projects yet conceived may be constructed, operated, and deployed. The Orbiting Wide-angle Light-collect

A possible “Space Factory” on the International Space Station (ISS) for “Grand Observatories” would permit a large astrophysical observatory in space. Grand-Observatories could revolutionize the great observatories that were hitherto pre-asse

A concept study to build great observatories on, and deploy from, the ISS is presented. Use of the ISS infra-structure including robotic arms and astronauts’ EVA would permit a construction of very large optical telescopes. We envisage that the sec

The Petawatt laser at LLNL has opened a new regime of laser-matter interactions in which the quiver motion of plasma electrons is fully relativistic with energies extending well above the threshold for nuclear processes. We have developed broad-band

Energy spectra of high energy cosmic ray nuclei and interaction studies from JACEE experiments are described with a particular emphasis on the energy region close to the ‘‘Knee’’ (100–1000 TeV/nucleus) and high density nucleus–nucleus int
