Energy lost by a particle beam in a lossy coaxial liner with many holes

Abstract:
In the framework of Bethe's modified theory we study the energy lost by
a relativistic particle beam travelling in a coaxial liner with many
holes, including the
effect of attenuation in the coaxial region.
The interference among the holes is the main source of losses and
is affected by the attenuation in the coaxial only on sufficiently long
distances. We derive analytical formulae for all the interesting
quantities and
a particular attention is given in clarifying the physical meaning;
numerical examples are considered using
the LHC nominal parameters.
