Open the CIPO recordAbstract From the Canadian patent
An electron gun is controlled by a system which stores the characteristics of the gun in a random access memory. The contents of the memory feed an electron gun driver which properly biases the gun. The characteristics of the gun are stored in the memory by using a collector to sense the electron beam. A comparator is connected to the collector and a reference brightness signal generator. The output of the comparator controls the storage of the characteristics in the memory.
