The time-of-flight (TOF) type neutral particle analyzer has been developed, calibrated and tested for the Large Helical Device (LHD) from FY1997. The plasma experiments on LHD has aggressively stared from FY1998. The analyzer has been installed at the same time. The preliminary data have been obtained from the latter half of FY1998. The routine data acquiring could be done from FYI999. The behaviors of high energy particles from NBI and ICH could be clear by using horizontal scan of the analyzer. The spectrum of the high energy particles agreed with those from the simulation. The tuning of TOF analyzer has been helped a lot by the Frascati people. Concerning about the analyzing the data has been discussed with them because they have experience of the calibration with the analyzer.The advanced multi-layer pellet injection device has been developed by the corroboration between Japanese and Russian scientists from FY1997 to FY1998. The pellet injection experiments have been performed in the Compact Helical System (CHS). The ion transport - coefficient could be obtained by measuring the spatial distribution of the emission intensity from the pellet. The result was in quite good agreement with the theoretical result. The device has also been installed in LHD from FY1999. At the end of the third experimental campaign, a few pellet injections could be succeeded and some data about the impurity transport could be obtained. In LHD, the sufficient comparison between the experimental and theoretical results could not be performed due to the lack of the data amounts. We expect the result in the next campaign because the preliminary trial was succeeded

从 1997 财年开始，飞行时间 (TOF) 型中性粒子分析仪已针对大型螺旋装置 (LHD) 进行了开发、校准和测试。 LHD 上的等离子体实验从 1998 财年开始积极开展。分析仪已同时安装完毕。初步数据是从1998财年下半年获得的。常规数据采集可以从FYI999开始完成。通过分析仪的水平扫描可以清楚地了解来自NBI和ICH的高能粒子的行为。高能粒子的光谱与模拟结果一致。 TOF分析仪的调优得到了Frascati人员的大力帮助。由于他们有分析仪校准的经验，因此就数据分析问题与他们进行了讨论。先进的多层颗粒注射装置是由日本和俄罗斯科学家从 1997 财年到 1998 财年共同开发的。颗粒注射实验是在紧凑螺旋系统（CHS）中进行的。离子传输系数可以通过测量颗粒发射强度的空间分布来获得。结果与理论结果非常吻合。从 1999 财年起，该设备也已安装在 LHD 中。在第三次实验结束时，可以成功进行几次颗粒注射，并可以获得一些有关杂质传输的数据。在LHD中，由于数据量的缺乏，无法对实验结果和理论结果进行充分的比较。我们期待下一次活动的结果，因为初步试验已经成功
