| 内容記述 | The charge resolution (dZ) for heavy ions (nuclear charge: Z < 40) of 0.1–1 GeV/n energy in CR-39 plastic nuclear track detector (PNTD) and its dependence on etching time, and on projectile Z and energy were investigated and optimized as part of an effort to make precise measurements of projectile charge-changing cross sections. Two types of CR-39 PNTD, HARZLAS TD-1 and BARYOTRAK, were exposed to heavy ion beams with seven values of Z behind thick targets to produce projectile fragments. Following chemical etching (7 N NaOH at 70 degreeC) for varying etch times, dZ of the projectiles was determined for each detector type. A strong dependence of dZ on the amount of bulk etch (B) was seen. It was also observed that dZ can be remarkably improved with longer etching time as a function of B^-{1/2}, in accordance with the trend seen in other types of track detector such as glass nuclear track detector. However, for B > 60 lm(30 h etching), saturation occurs and there is no further improvement in dZ. Analysis of the correlations between projectile Z, energy, detector response, and fluctuation of the response make it possible to develop a model to predict the dZ for projectiles of given Z and energy. The predicted and measured values of dZ show good agreement within 10%. We conclude that 4 < Z < 30 at intermediate energy can be identified with good dZ in these detectors. The predictive model will be used in designing future cross section measurement experiments. | |||||
