Networking for high energy physics in Japan

The computer network for high energy physics in Japan has grown over the fist five or six years and still expanding. Its original purpose was to provide the collaborators in universities access to the computing resources in KEK. Adding to the remote login from terminals, VAXs or Fujitsu computers located in universities have been connected to KEK's computers by DECnet or FNA (Fujitsu's SNA) and have formed the “Japanese HEPnet”. Since the link between LBL and KEK was established in June 1987, the Japanese HEPnet is combined with the American HEPnet and is an indispensable tool for international collaboration. The current communication media for Japanese HEPnet, leased lines and public X.25, are being replaced by Gakujo-net (Monbusho's inter-university private X.25 network). DECnet, FNA, IP and Ethernet-bridge will run on Gakujo-net for the Japanese HEPnet.

High energy physics computing in Japan

A brief overview of the computing provision for high energy physics in Japan is presented. Most of the computing power for high energy physics is concentrated in KEK. Here there are two large scale systems: one providing a general computing service including vector processing and the other dedicated to TRISTAN experiments. Each university group has a smaller sized mainframe or VAX system to facilitate both their local computing needs and the remote use of the KEK computers through a network. The large computer system for the TRISTAN experiments is described. An overview of a prospective future large facility is also given.

Special Issue: Physics in Japan

Because of Japan's recent remarkable achievements in science and industry, we offer you this special issue on physics in Japan. The articles all deal with topics where Japanese physicists are working at the frontiers of knowledge.

Underground physics in Japan, present and future

This paper proceeds in three parts: i) We first review underground facilities in Japan. ii) Next, we show Super MUTRON project which is planned to progress at the Ohya-cho underground. The most important purpose of Super MUTRON is to detect muon pairs and muon bundles expected from quark gluon plasma and other processes. iii) Finally, we discuss about Japanese projects which will be completed at the Gran Sasso tunnel.

Large‐Volume High‐Pressure Mineral Physics in Japan

American high‐pressure research with large sample volumes developed rapidly in the 1950s during the race to produce synthetic diamonds. At that time the piston cylinder, girdle (or belt), and tetrahedral anvil devices were invented. However, this development essentially stopped in the late 1950s, and while the diamond anvil cell has been used extensively in the United States with spectacular success for high‐pressure experiments in small sample volumes, most of the significant technological advances in large‐volume devices have taken place in Japan. Over the past 25 years, these technical advances have enabled a fourfold increase in pressure, with many important investigations of the chemical and physical properties of materials synthesized at high temperatures and pressures that cannot be duplicated with any apparatus currently available in the United States.

ASPUN, Design for an Argonne Super Intense Pulsed Neutron Source

Argonne pioneered the pulsed spallation neutron source with the ZING-P and IPNS-I concepts. IPNS-I is now a reliable and actively used source for pulsed spallation neutrons. The accelerator is a 500 MeV, 8-9 ..mu..a, 30 Hz rapid cycling proton synchrotron. Other neutron spallation sources are now in operation or in construction. These include KENS-I at the National Laboratory for High Energy Physics in Japan, the WNR/PSR at Los Alamos National Laboratory, and the SNS at the Rutherford Appleton Laboratory in England. Newer and bolder concepts being developed for more intense pulsed spallation neutron sources include SNQ at the KFA Laboratory in Germany, ASTOR at the Swiss Institute for Nuclear Physics, and ASPUN, the Argonne concept. ASPUN, presented in this paper, is based on the Fixed-Field Alternating Gradient concept. The design goal is to provide a time-averaged beam of 3.5 ma at 1100 MeV on a spallation target in intense bursts, 100-200 nanoseconds long, at a repetition rate of no more than 60 to 85 Hz. Design parameters are given.

Tristan project and KEK activities

Abstract An outline of recent activities of the National Laboratory for High Energy Physics in Japan (KEK) is given with an emphasis on its TRISTAN Project.

Recent advances in fire physics in Japan

Some recent studies concerned with fire physics in Japan are considered. The studies are classified in two groups, one which deals with fire in its broad sense and includes mathematical fire modeling, model experiments, studies on an overall characterization of fire, and a statistical approach: the other group includes research projects to clarify particular aspects of fire which may lead to improvements in the sub-programmes of fire modeling. The involvement between phenomenological fire research and the systems approach to fire safety design is also discussed.

Beam-loss monitoring system with free-air ionization chambers

A monitoring system for proton beam losses was installed in the proton synchrotron at the National Laboratory for High Energy Physics in Japan (KEK). The system consists of 56 air ionization chambers (AIC) for radiation detectors, 56 integrators, 56 variable gain amplifiers, two multiplexers, a computer interface circuit, a manual controller and a high tension power supply. The characteristics of the AIC, time resolution, radiation measurement upper limit saturation, kinetic energy dependence of the sensitivity, chamber activation effect, the beam loss detection system and the results of observations with the monitoring system are described.

Reports on progress in polymer physics in japan

Abstract The Research Group of Polymer Physics in Japan, in cooperation with the Research Group of Polymer Solutions, publishes an annual summary of the work done on high polymer physics in Japan. The publication consists of short reports (2 to 4 pages) describing current or recently completed research. This journal, in cooperation with Professor S. Oka, Chief Editor of the Report, publishes the table of contents of each issue as soon as it is available. Papers on biophysical matters are also included, since Annual Reports of the Research Group in Biophysics in Japan has been discontinued. Copies of the complete report (and back issues) can be obtained from:
