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
It is a measure of the extent up to which a material concentrates electrostatic lines of flux. It is the amount of the stored electrical energy when a potential is applied, relat
A set of open circuit test and short circuit test have been performed on a transformer. A supply voltage of 480 V is applied to the primary side of the transformer and the followin
actually in my college we are going to celebrate department function for physics we have to keep demos in physics for a project but i don''t have any idea will u help me
An electron is unrestricted from rest at a point in an evacuated region of space at which the electric potential is 5.0 volts. No force except the force of the electric field chara
is motion of a ball on a smooth surface an example of uniform velocity? is motion of a ball on a rough surface an example of variable velocity? is a car moving on a straight path
ohmmeters: The use of ohmmeters is somewhat more involved. Most importantly when measuring resistance the circuit power must be switched off, power is derived from within the i
The magnetic field of Earth resembles the field of a bar magnet. The north pole of a compass needle, used for navigation, generally points toward the geographic north pole.
The Josephson effect is a term given to the phenomenon of current flow across two superconductors separated by a very, thin insulating barrier. This arrangement, two superconductor
what are characteristics of simple harmonic motion
The light is incident on a rotating Nicol prism and the intensity of the emergent light beam becomes zero and maximum periodically. What we can derive about the state of polarizati
