Solid state simeconductor
It is main advantage is that it has much better resolution than NaI(Tl)It is main disadvantages are that it is not available in large sizes and it is much more expensive.
The principle of operation :its acts as a solid ionization chamber so it acts as an insulator and dose not allow current to flow until ionization has taken place in its volume. It kept very cold to minimize the current produced by thermal activation of electrons.
Collimator: it is used on the scintillation detector to limit its counting volume. It is a specially designed lead shield with one or more holes in
It has two types:1 – The open flat field collimator: it is useful for detecting gamma rays from a relatively large volume such as the thyroid or kidney.2- The focused collimator : it has a number of trapped holes oriented to point at a small volume 7.5 to 12.5 cm from it , it is often used in nuclear medicine
write all equationes of projectile motion used in calculation of vertical and horizontal motion
Translational : If a body goes such that its orientation does not change with respect to time then body is said to move in translational motion. ROTATION : If an object is rota
why at critical temperature in superconductors resistance becomes zero? Solution) For conductors as the temperature increases their rasistance increases and as temperature decreas
