Question

______ is the number of electrons hitting the work piece per second.

1) Acceleration voltage
2) Travel Speed
3) Beam Current
4) Beam Velocity

Answer 1

Beam current is the number of electrons hitting the work piece per second.

Step-by-step explanation:

The number of electrons hitting the work piece per second is known as beam current. Beam current refers to the flow of charged particles in a beam and is measured in mA (milliamperes) or A (amperes). It represents the rate at which electrons are passing through a cross-sectional area.
