Review of Muon Catalyzed Fusion Experiments – Activities after EXAT98 and Future Perspectives

Since EXAT98 at Ascona, significant progress has been marked for experimental investigations of the fundamental understanding of muon catalyzed fusion (μCF) phenomena in D–T, D₂ and other hydrogen systems. Future progress in the μCF studies is now guaranteed due to the successful launching of advanced accelerator projects such as JAERI-KEK Joint Proton Accelerator project and RI Beam Factory project at RIKEN. Also, the start of the next-phase thermal nuclear fusion project of ITER becomes promising so that some future contributions from ITER to μCF or vice-versa can be expected for various physical or technological aspects of fusion research. The future progress of μCF studies will also be promoted because of the growth of various other scientific research using muons. The essence of all these subjects is reviewed.

The Muon Science Facility at the JKJ Project

The muon science facility is one of the experimental arenas of the JKJ project, which was recently approved for construction in a period from 2001 to 2006, as well as neutron science, particle and nuclear physics, neutrino physics and nuclear transmutation science. The muon science experimental area is planned to be located in the integrated building of the facility for the materials and life science study. One muon target will be installed upstream of the neutron target in a period of phase 1. The beam line and facility are designed to allow the later installation of a 2nd muon target in a more upstream location. The detailed design for electricity, cooling water, primary proton beam line, one muon target and secondary beam lines (a superconducting solenoid decay muon channel, a dedicated surface muon channel, and an ultra slow muon channel) is underway. In the symposium, a latest status of the muon science facility at JKJ project will be reported. This revised version was published online in August 2006 with corrections to the Cover Date.

The glassy phase of Gallager codes

Gallager codes are the best error-correcting codes to date. In this paper we study them by using the tools of statistical mechanics. The corresponding statistical mechanics model is a spin model on a sparse random graph. The model can be solved by elementary methods (i.e. without replicas) in a large connectivity limit. For low enough temperatures it presents a completely frozen glassy phase (q _EA = 1). The same scenario is shown to hold for finite connectivities. In this case we adopt the replica approach and exhibit a one-step replica symmetry breaking order parameter. We argue that our ansatz yields the exact solution of the model. This allows us to determine the whole phase diagram and to understand the performances of Gallager codes. Received 9 April 2001

What is Conservation Science?

‘Conservation science’ or ‘cultural heritage research’ is defined through a discussion of research needs, training and employment patterns world-wide, and trends in published work. Parallels with mainstream polymer science are drawn throughout. Some aspects are discussed in more detail: traditional paint composites; studies in modern, synthetic, paint composites; the relevance of accelerated ageing to a range of polymer types.
