title: A Cerenkov detector for energy calibration of electron accelerators in clinical use.
abstract: The ICRU recommends various methods for the energy calibration of electron accelerators in medical use. A simple method, so far rarely used, is based on the Cerenkov effect in gases. The method is described and its practical application discussed. Corrections and error effects on the energy determination are investigated in detail.
