Use of a laddertron chain in Orsay MP tandem

Abstract

We decided to use a laddertron at the Orsay MP tandem in place of the belt, the lifetime of which was too short. The new charging system was installed at the beginning of 1979 and, after various failures during the first months of operation, is now reliable. A short review of the accelerator's improvements is given, as well as the operating characteristics since the installation of the laddertron.
