Comparison of Two Methods of Detecting Ice Crystal in Cloud Chamber

Sugar solution and cooled glass slide are usually used to collect ice crystals in cloud chamber. The ice crystal counting numbers by using these two methods are compared in a small mixed cloud chamber. The results show that ice crystal number detected by glass slice is several times higher than by sugar solution. The upper and lower detecting limit of two methods are estimated. The merits and demerits, and the applied range of them are also discussed.
