The International Workshop on JHF Science (JHF98)
Japproval by the Japanese government. An International Workshop on JHF Science ("JHF98") was held at KEK between March 4th and March 7th as a part of the preparation for the JHF project, especially because it will be a facility for international collaborations. Number of registered participants were 441. ( Japan 322, U.S. 37, Canada 18, China 4, Taiwan 4, India 5, Korea 4, U.K. 8, France 3, Germany 10, Swiss 10, Austria 2, Italy 7 and Russia 7). This was beyond what was expected and the JHF project received great encouragement from the international science community of broad discipline.
The main goal
The main goal of the workshop was to draw a clearer picture on real experiments at JHF. Intensive discussions were done on goals of experiment(s), their importance in physics and requirements for beam characteristics, beam lines, detectors, experimental floors and others. Since the JHF is a multi-purpose accelerator facility, the topics covered were diverse as expected. The workshop started with plenary sessions.
Plenary sessions
Speakers and topics were:
S. Nagamiya (JHF Project), S. Wojcicki (Neutrino Oscillation), W. Marciano (Rare Processes and Related Physics), V. Metag (Future Prospects in Nuclear Physics and the JHF), M. Oka (QCD Nuclear Physics), Y. Mori (JHF Accelerator), W.I.F. David (Material Sciences with Neutron Beams), J. Trewhella (Biological Sciences with Neutron Beams), S. Cox (Muon Science), G. Mathews (Nuclear Astrophysics with RI Beams) and R. Kiefl (From Nuclear Sciences to Material Sciences).
The four experimental facilities
JHF facility is designed to have four experimental facilities, called K-, N-,M- and E-Arena, to accommodate various experimental needs. Hence the parallel sessions were divided into sessions related to particulars of each arena for most of them. (Although each arena is not totally independent from each other and overlapped regions were covered by other sessions including plenary sessions.) Topics for each arena were,.
| (1) |
K-Arena : kaon and muon rare decays, neutrino physics, strangeness nuclear
physics, physics with primary beams, and hadron spectroscopy and physics with nti-proton and anti-nuclei. |
| (2) |
N-Arena : solid target technology, new science with neutrons, and fundamental physics with neutrons. |
| (3) |
M-Arena : next generation µSR experiments. |
| (4) |
E-Arena : facilities, nuclear astrophysics, fundamental and nuclear physics with ISOL-based RNB, material science, post accelerators, and production targets and ion sources. |
Part of the working sessions of the E-arena was held as the KEK and TRIUMF Joint Workshop on Physics and Techniques of Radioactive Nuclear Beams. In conjunction with JHF98, “Multi-Purpose Hadron Working Group Meeting for the OECD Mega Science Forum (Nuclear Physics)” was also held at KEK on March 3rd and in the afternoon on March 7th.
And the evenings were...
Not only the daytime sessions were lively, but banquet and parties were filled with good discussions that went quite well with good food and drinks.
