(一)仪器装置自制卧式玻璃热空心阴极放电管,长16厘米,外径5厘米,内径3厘米。该放电管的特点是:体积小,电极不需预烧、不需屏蔽,可达到稳定放电。动态平衡式载气供气系统。自制高压稳流电源,电压1000伏,最大电流1000毫安。 (二)条件实验在用氩作载气的热空心阴极光源中,试样的气化主要是热蒸发,同时也有溅射作用。决定气化的重要因素是放电电流和放电时间。为了选
(A) of the instrument device Self-made horizontal glass hot hollow cathode discharge tube, length 16 cm, an outer diameter of 5 cm, an inner diameter of 3 cm. The discharge tube is characterized by: small size, the electrode without pre-burning, without shielding, stable discharge can be achieved. Dynamic Balanced Carrier Gas Supply System. Home-made high-voltage power supply, voltage 1000 volts, the maximum current 1000 mA. (B) conditions experiment In a hot air cathode with argon carrier gas, the sample gasification is mainly thermal evaporation, but also have a sputtering effect. Important factors that determine gasification are the discharge current and the discharge time. In order to choose
