Experience with the 30 MeV Synchrotron as a Madiotherapeutic Instrument I. Development, Calibration and Instrumentation

Abstract
The 30 MeV synchrotron provided by the British Medical Research Council was installed at the Radiotherapeutic Centre, Addenbrooke''s Hospital, Cambridge in November 1949. The general principles of the application of high energy rorntgen rays to radiotherapy are discussed. Some details of the 30 MeV synchrotron are given. The developments preparatory to the use of synchrotron in radiotherapy are discussed. Special attention has been paid to accurate energy (megavol-tage) calibration and developments in the field of electronic instrumentation. Some of these developments appear to be capable of general application in radiotherapy.
