Question

Please discuss the operation of the x-ray tube Make a diagram and explain the operation principles. What are the advantages/limitations of large vs. small anode target on the image/operational principles?

Answer 1

X - rays are also called gamma rays It�s frequency is approximately 1020 They are widely used in medical field. Working - X Ray tube consists of high vacuum tube , heater, Cathode and anode Vacuum tube operates at very high voltage Whenever heater, anode and cathode is supplied voltage, the Cathode emits electrons that frames towards anode with a very high speed The electron beam emitted from the Cathode strike the anode at a speed such that new rays are made from the slating surface of anode Hence X - rays seam to bounce side ways. \r\n The beam intensity can be controlled by adjusting the voltage The anode is made up of tungsten alloy Advantages of using large anode target on the image Heating of anode is less X - rays yield is more Limitation of Large anode target It�s spatial resolution is reduced It�s unsharpness increases Limitations of using small anode target Heating of anode
