在J-PARC主环（MR）中加速的30 GeV质子束通过第三次整数共振提取被缓慢提取并输送到强子实验装置。消色差条件下的动态凸块计划大大降低了束流命中率的隔膜设备，我们已经达到了51千瓦SX操作在5.2秒的周期与高慢提取效率为99.5%。指示所提取的射束的时间结构的均匀性的溢出占空因数通常为50%。目前的SX性能和未来的改进计划将提出。
A 30 GeV proton beam accelerated in the J-PARC Main Ring (MR) is slowly extracted by the third integer resonant extraction and delivered to the hadron experimental facility. A dynamic bump scheme under achromatic condition drastically reduces beam hit rate on the septa devices, and we have attained 51 kW SX operation at 5.2 s cycle with high slow extraction efficiency of 99.5%. A spill duty factor indicating a uniformity of the time structure of the extracted beam is typically 50%. The current SX performance and future plans for improvements will be presented.
