High-pressure solid hydrogen target for muon catalyzed fusion
- 161 Downloads
We have developed a high-pressure solid hydrogen target for muon-catalyzed fusion to study temperature dependence of fusion cycling rates and muon loss probabilities in solid hydrogen at higher temperature than the melting point. The constructed target is a simple standalone-system consisting of a solid hydrogen target, a high-pressure generator, an isolation valve and a buffer tank. The solid hydrogen target and high-pressure generator are independently cooled down and temperature-controlled by closed-cycle helium-refrigerators. In the performance test, the solid D2 target was formed successfully at 33.6 K with applying D2 gas pressure at 79 MPa.

We would like sincerely to appreciate Dr. A. J. Caffrey and Dr. J. Zmeskal for valuable discussions and suggestions on technical issues of high-pressure solid hydrogen target. We would also like to thank Mr. T. Kawaguchi for discussions during the designing, manufacturing and performance test. The present work was supported in part by RIKEN Director’s fund (RIKEN’s strategic programs for R&D).
