Abstract

Recent studies have shown that Allyl Diglycol Carbonate, commercially known as CR-39 (the most sensitive among etch track detectors) can detect relativistic oxygen and other heavier nuclei. We are using large sheets of special grade CR-39 (DOP) in our experiment in Space Shuttle Spacelab-3. As CR-39 is a highly brittle substance, special care is required to cut CR-39 sheets, especially in case of large sheets and circular cuts. A study of cutting of CR-39 sheets using laser light is described in this paper. It has been found that this method is sufficiently fast to handle large number of sheets and also equally safe for big sheets. A maximum speed up to 200 cm/min with a 5× 104 W/cm2 laser is obtained during the present study. This study also shows that laser cutting does not affect the track properties of CR-39.
