Abstract: The ability of synchrotrons to accelerate particles with different e/m0 values is dependent upon being able to control its accelerating-voltage frequency as a function of the actual guide field value. Interpolation between modification values can be performed to reduce the possibility of exciting phase oscillation. Differences between the desired frequency and the actual frequency produced (due to non-linearities in the system) are also removed with the digital processor increasing the precision of the system up to two orders of magnitude. Successful operation with six different particles has been demonstrated.
