title: Operating characteristics of the Dynaray 18 linear accelerator.
abstract: The operating system of a Dynaray 18 linear accelerator is described. Central axis depth dose data for the 10 MV roentgen ray beam are given and compared with published data. The alignment of the roentgen ray beam and the modifications required to obtain satisfactory uniformity and reliable dosimetry are described. The characteristics of the electron beams are also described, central axis depth dose data are given and the derived estimates of energy are discussed.
