Abstract
An apparatus for measuring radiotherapy beam dose can include a pair of plates for generating a voltage between the pair of plates, a beam detection volume arranged at least in part between the pair of plates, and a voltage sensor arranged on a surface of at least one plate of the pair of plates. The voltage sensor can be configured to and arranged or located to sense a voltage generated across at least part of the beam detection volume.
