WebGas Discharge Tubes Principle： The basic principle of GDT is Gas discharge. The pulse breakdown voltage (Vsi) of the commonly used discharge tube ranges from a few hundred volts to more than one thousand volts. The discharge tube was originally in an open circuit state, with a large impedance and a small capacitance value. WebAt the temperature in the gas discharge tube, more atoms are in the n = 3 than the n ≥ 4 levels. Consequently, the n = 3 to n = 2 transition is the most intense line, producing the characteristic red color of a hydrogen discharge (part (a) in Figure 7.3.1 ). Other families of lines are produced by transitions from excited states with n > 1 to ...
