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
An electric motor with a load delivers 5.2 hp to its shaft (1 hp = 746 W). Under these conditions, it operates at 82.8 percent efficiency. a. How much current does the motor d
a) Amplitude : It is the main value of distance of the particle from its equilibrium position. b) Time period (T): Smallest time interval after which the oscillatory motion
Q. Illustrate what two properties of electromagnetic waves are used to attach info to radio signals? Answer:- By changing the amplitude of a radio wave you can encode info
A data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel is called band width.
Who manufactures optical ports? All system integrator generate a particular type of optical port to attach to their choice of illuminator.
What is common end? The fiber or fibers should be connected to the illuminator. Particularly in the case of a number of fibers, these have to be bunched together and contain se
