Abstract
The JET (Joint European Torus) neutral beam injection (NBI) system, has demonstrated a very high degree of reliability and availability. Data on the reliability and availability of the beamlines and the associated subsystems (e.g. power supplies, cooling and cryogenic supplies, computerized control, etc.) have been recorded over the past three years. These data are used to quantify the overall reliability of the NBI systems and to identify problem areas. The overall reliability (energy injected into JET/energy requested) and availability for the 1990 experimental campaign are both better than 80% and improve significantly during routine operation to nearly 90% after the system has been fully commissioned.<>
JET (Joint European Torus)中性束注入(NBI)系统已经证明了非常高的可靠性和可用性。过去三年记录了有关光束线和相关子系统(例如电源、冷却和低温电源、计算机控制等)的可靠性和可用性的数据。这些数据用于量化NBI系统的整体可靠性,并确定问题区域。总体可靠性(注入JET的能量/要求的能量)和1990年试验活动的可用性都优于80%,并且在系统完全投入使用后,在常规操作期间显着提高到接近90%。
