Times Cited Count：0 Percentile：0.01(Nuclear Science & Technology)For a steady state operation of JT-60SA, a plasma feedback control using various diagnostic sensor signals plays an essential role. To realize this, Real Time Diagnostic Signals acquisition System, RTDS, which utilizes PC-based real-time OS "INtime", has been under consideration toward JT-60SA project. Moreover, long-time experiments more than 100 seconds will be planned in JT-60SA project. Therefore, real time monitoring will be required as an essential function that displays acquired diagnostic signals on real time during long-time experiment. This function will be also realized by utilizing RTDS.

The accelerator served mainly for graft-polymerization for new material development, radiation effect study on semiconductors and various experiments of visiting users. The annual operation time of the electron accelerator was 947.9 h. The Co-60 -ray irradiation facilities consist of three buildings and cover a wide dose-rate range from 0.04 Gy/h to 20 kGy/h with eight irradiation rooms. The first irradiation facility served mainly for radiation-resistance testing of cables used in nuclear power plants. The second irradiation facility (No.6 irradiation room) operated as hourly scheduled. The food irradiation facility served radiation at lower dose rates. The annual operation time for the first, second cobalt irradiation facilities and food irradiation facility was 15,971 h, 12,389 h and 7,681 h respectively.

P(
, )S reaction rate at temperatures characteristic of explosive hydrogen burning in classical novae and type I X-ray bursts. Specifically, the rate had been previously predicted to be dominated by two low-lying, unobserved, levels in the 
=4.7-4.8 MeV region, with spin and parity assignments of 3
and 2. In recent experimental work, two candidate levels were observed with energies of 4.699 MeV and 4.814 MeV, but no experimental information on their spins and parities was obtained. We have performed an in-beam -ray spectroscopy study of S with the Si(He, )S reaction. The spin and parities were inferred from a comparison to the known decay schemes of the corresponding mirror states.
