The basic electrical parameters of an electron beam processor are its acceleration voltage, the electron beam current, and the electron beam power. The ratio of electron beam power and the input electrical power defines the efficiency of an electron accelerator. The acceleration voltage determines the energy of the electrons, as pointed out in Section 2.2. 

The absorption properties of the accelerated electrons in the processed materials are the absorbed dose, the depth dose profile, the penetration range, and the dose rate. 

Process parameters involve line speed if dose rate and line speed are combined, the dose delivered to the product to be cured can be calculated. A processor specific yield factor depends on the relationship between the beam current 

Acceleration voltage Potential difference between cathode and anode of the accelerator, usually expressed in kV or MV and obtained using a resistive voltage divider chain in the high-voltage unit.
