Material of the target

Vedclass · Answer

(A) The ratio of the number of secondary electrons emitted to the number of primary electrons incident is known as the secondary emission coefficient $\delta$.This coefficient $\delta$ is primarily a property of the target material and the energy of the primary electrons.However, in the context of standard physics problems regarding electron emission, if the question asks what determines the total number of secondary electrons emitted, it is directly proportional to the intensity (number of incident primary electrons) of the primary beam.Given the options provided, the secondary emission coefficient itself is a material property, but the total count of secondary electrons depends on the intensity of the primary beam.Therefore, the most appropriate answer is (A) Material of the target, as $\delta$ is a characteristic constant for a given material.

The number of secondary electrons emitted per number of primary electrons depends on:
