The results of this R & D are divided into the following fourth items ;(1)The completion of optical apparatus for determining the locations of penetrated holes produced by etching :This optical method was proposed by this group. In this method, a BP-1 plate was put on a light source of VUV, the track pattern in Bp-1 plate was taken by a CCD camera from the top of the plane. Using this method, the penetrated holes of【greater than or equal】 50 micron in diameter were detected. Another method, in which a visible light source can be used, was also developed. The scanning speed of these methods is about ten times faster than that of the ammonia method which was planned to be used by the US-ECCO group.(2)Speed up in track scanning ;Using a line of CCD in place of a spot of CCD, we succeeded in speed up of the automatic track scanning by about 50 times of that of spot CCD. This device gave a revolutionary impact to the field of automatic data analysis. By this improvement, we found that many … More automatic scanners are not always needed for the analysis for massive track data.(3)Development of automatic sample changer :In order to automatically operate the system for track data analysis, we need automatic track-sample changer. For that, we constructed a new sample changer for our automatic track scanner. At present, we do not master its usage, yet, but, in near future, it will be very useful for automatic track data analysis.(4)Mass identification due to CR-39 and Bp-1 :In the space experiment for cosmic ray particles heavier than iron, the mass identification power in track detectors is very important, because it will extent the field of view in the cosmic ray particle investigation. Therefore, during four years, we investigated the mass resolution ofCR-39 andBp-1 plates and found that the mass resolution (rms) of 0.2 amu for iron isotopes was achievable in CR-39 and it of Bp-1 was 0.4-0.5 amu for krypton isotopes. These abilities of CR-39 and Bp-1 may apply to identification of isotopes around Xe and I, which exist alternatively. Less

本研究开发的成果分为以下第四项：（1）完成了用于确定蚀刻产生的穿透孔位置的光学装置：该光学方法由该小组提出。该方法将BP-1干版置于真空紫外光源下，用CCD摄像机从干版上方拍摄干版上的径迹图案。使用该方法，检测到直径[大于或等于] 50微米的穿透孔。还开发了另一种方法，其中可以使用可见光源。这些方法的扫描速度比US-ECCO小组计划使用的氨法快约10倍。（2）轨道扫描速度的提高：用一行CCD代替一点CCD，成功地将自动轨道扫描速度提高了约50倍。该设备对自动数据分析领域产生了革命性的影响。通过这种改进，我们发现许多 ...更多信息 对于大量轨道数据的分析，并不总是需要自动扫描仪。（3）自动换样器的研制：为了实现系统的自动化运行，进行径迹数据分析，我们需要自动径迹换样器。为此，我们为我们的自动轨道扫描仪构建了一个新的进样器。目前，我们还不掌握它的用法，但在不久的将来，它将是非常有用的自动跟踪数据分析。（4）CR-39和Bp-1的质量鉴别：在比铁重的宇宙线粒子的空间实验中，径迹探测器的质量鉴别能力是非常重要的，因为它将扩大宇宙线粒子研究的视野。因此，我们用四年时间研究了CR-39和Bp-1板的质量分辨率，发现CR-39板对铁同位素的质量分辨率可达0.2amu，而Bp-1板对氪同位素的质量分辨率为0.4- 0.5amu。CR-39和Bp-1的这些能力可能适用于鉴定交替存在的I和I周围的同位素。少
