The voltage in an EBW operation is 45 kV. The beam current is 50 milliamp. The electron beam is focused on a circular area that is 0.50 mm in diameter. The heat transfer factor is 0.87. Calculate the average power density in the area in watt/mm2.

Explanation:

From the question we are told that:

Voltage

Current

Diameter  

Heat transfer factor

Generally the equation for  Power developed is mathematically given by

Therefore

Power in area

Power Density
