In this post we are going to discuss about gas filled x ray tube which is used to produce x rays
Gas-filled X-ray tube :
Fig. 1.1 represents an early form of X-rays tube similar to that of a Rontgen tube. G is a glass bulb exhausted to a pressure of 10-³ mm of Hg. C is a concave cathode made of aluminium, which focusses the beam of cathode rays on a target T. Tungsten is used as the target because of its high melting point. This is surrounded by a massive block of copper which helps in the quick dissipation of heat produced by the cathode rays when they are stopped by the target. The target and the copper block together is called the anti-cathode (A.C.), A is a separate anode which
