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

Consider a pentavalent impurity such as phosphorus (P, Z = 15) is doped in a pure semiconductor germanium (Ge, Z = 320. Each phosphorus atom forms four covalent bonds with four ger
Voltage division: In a series circuit Ohm's law applies for each component. However, since the current is common to all components we have: V1 = IR1, V2 = IR2,
ROCKET PROPULSION: The motion of a rocket is an application of the law of conservation of momentum and Newton's 3rd law of motion. The gases ejected out from the combustion cha
