RF accelerating structures
<p>The main aim of this work is to present a simple<br>
method, based on analytical expressions, for obtaining the temperature<br>
increase due to the Joule effect inside the metallic walls<br>
of an RF accelerating component. This technique relies on solving<br>
the 1D heat transfer equation for a thick wall, considering that<br>
the heat sources inside the wall are the ohmic losses produced<br>
by the RF electromagnetic fields penetrating into the metal with<br>
finite electrical conductivity. Furthermore, it is discussed how the<br>
theoretical expressions of this method can be applied to obtain<br>
an approximation to the temperature increase in realistic 3D<br>
RF accelerating structures, taking as an example the cavity of<br>
an RF electron photoinjector and a travelling wave linac cavity.<br>
These theoretical results have been benchmarked with numerical<br>
simulations carried out with a commercial Finite Element Method<br>
(FEM) software, finding good agreement among them. Besides,<br>
the advantage of the analytical method with respect to the<br>
numerical simulations is evidenced. In particular, the model could<br>
be very useful during the design and optimization phase of RF<br>
accelerating structures, where many different combinations of<br>
parameters must be analysed in order to obtain the proper<br>
working point of the device, allowing to save time and speed<br>
up the process. However, it must be mentioned that the method<br>
described in this manuscript is intended to provide a quick<br>
approximation to the temperature increase in the device, which of<br>
course is not as accurate as the proper 3D numerical simulations<br>
of the component.</p>
