In which of the following types of CRT technology flood guns bombard the phosphorus surface of the tube ___________________.
The correct option is A Direct view storage tube
Direct view storage tube types of CRT technology flood guns bombard the phosphorus surface of the tube.
Direct-view storage tube was an acronym used by Tektronix to describe their line of storage tubes. These were cathode ray tubes (CRT) that stored information written to them using an analog technique inherent in the CRT and based upon the secondary emission of electrons from the phosphor screen itself.
The direct view storage tube behaves like a CRT with highly persistent phosphor. Pictures were drawn on there will be seen for several minutes (40-50 minutes) before fading. It is similar to CRT as far as the electronic gun and phosphor-coated mechanisms are concerned. But instead of the electron beam directly writing the pictures on the phosphor coated CRT screen, the writing is done with the help of a fine-mesh wire grid.
The grid made of very thin, high-quality wire, is located with a dielectric and is mounted just before the screen on the path of the electron beam from the gun.
