Abstract:
In order to have efficient particle acceleration it is fundamental
that the particles experience, in the accelerating
gap, field amplitudes as uniform and as high as possible
from gap to gap. Because of the unavoidable fabrication
errors, an accelerating structure, when assembled, exhibits
field values lower than the nominal ones and/or not uniform.
All the usual procedures developed in order to adjust
the parameter deviations responsible of the malfunctioning
of these structures, are based on field amplitude measurements,
by using the bead pull technique, which is a very invasive
technique. In this paper the philosophy is reversed:
it is assumed that all the information can be got by Sounding
the Modes of the whole System (SMS) and correct the
deviation of each frequency mode from its nominal value
by means of an appropriate tuning of the cavities: resorting
to a perturbative technique applied to a circuit model
representing this kind of structures, it is possible to calculate
the amount of tuning to give to the cavities. It will
be shown that a very good equalization and maximization
of the fields in the cavities can be achieved by using this
technique.
