| 内容記述 | A large scale observation program of ultra heavy nuclei (Z ≥30) in galactic cosmic rays (UH-GCRs) is planned with the use of solid-state track detectors (SSTD) such as CR-39 plastic and BP-1 glass on the International Space Station and on board long-duration balloon flights. The handling of SSTDs usually requires a large number of year x person to scan and analyze the etch pits produced on the detector. It is due to the manual or semi-automatic analysis using a conventional optical microscope system. We plan to use a cosmic ray telescope with a large exposure area of 20 m2 made of the SSTD stacks. Detector handling will be more difficult as compared with before. A major problem for such a large scale experiment is how to quickly and precisely analyze the etch pit obtained over a short period. We have developed a new microscope system, the HSP-1000, for high speed image acquisition that uses a line sensor camera in place of a traditional CCD camera. Continuous, automatic focusing of the microscope is achieved by means of an optical pick-up system that provides fast feedback for control of distance between the objective and the image surface. As a result of continuous stage motion and continuous focusing, we have attained image acquisition speeds that are 50–100 times faster than conventional CCD-based microscope systems. In this paper, we present the current status of developments of the high speed microscopic measurement system, fully automated plate changing system and estimations of analyzing time for large scale observations of ultra heavy nuclei. | |||||
