英文摘要Charged particle diagnosis is an important aspect of laser-plasma experiments conducted at super-intense laser facilities. In recent years, Columbia Resin #39 (CR-39) detectors have been widely employed for detecting charged particles in laser-plasma experiments. This is because the CR-39 polymer does not respond to electromagnetic pulses or X-rays. This study presents a method for calibrating the relationship between particle energy and track diameter in a CR-39 detector (TasTrak((R))) using 3-8MeV protons, 6-30MeV carbon ions, and 1-5MeV alpha particles. The particle tracks were compared under the manufacturer's recommended etching conditions of 6.25mol/l NaOH at 98 degrees C and under the widely adopted experimental conditions of 6.25mol/l NaOH at 70 degrees C. The results show that if the NaOH solution concentration is 6.25mol/l, then the temperature of 70 degrees C is more suitable for etching proton tracks than 98 degrees C and employing a temperature of 98 degrees C to etch alpha-particle and carbon-ion tracks can significantly reduce the etching time. Moreover, this result implies that C3+ ion or alpha-particle tracks can be distinguished from proton tracks with energy above 3MeV by controlling the etching time. This calibration method for the CR-39 detector can be applied to the diagnosis of reaction products in laser-plasma experiments.
