THE PRODUCTION BY SURFACE CURRENTS OF MAGNETIC FIELDS SUITABLE FOR SPIRAL RIDGE ACCELERATORS

摘要

The problem is treated of finding surface current distributions required to produce magnetic fields suitable for spiral ridge accelerator where the field is required to be zero outside the region of the current distributions and where media of two different permeable ties are used. The problem is reduced to the design of an "elementary magnet". The fine accelerator magnet can be formed of a single each magnet or built up using a number of them
