Research Abstract

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
