Four monitoring techniques that can determine peak voltage (V{sub p}) to a precision of {approximately}5% for high-intensity, pulsed electron accelerators operating in the 10 to 20 MV range are discussed and applied to the 14-TW HERMES III accelerator. The techniques utilize parapotential flow theory, the range of H{sup {minus}} ions, the bremsstrahlung from electron interactions with an electron target, and the photoneutron fluence form neutrons generated in a bremsstrahlung target. Applications of these techniques to HERMES III shows that when the accelerator is operating under nominal conditions, V{sub p} = (18.7 {plus minus} 0.7) MV. 16 refs.
