Abstract:
=========
As part of an R&D program to develop an input power coupler for the TESLA
project, a 1.3 GHz travelling wave window was designed, fabricated and tested.
The main advantages of this window are a reduced electric field at the brazing
location, low dielectric losses and protection of the ceramic from the direct
view of the electrons coming from the cavity. Two versions of this window were
fabricated (one with titanium as the outer conductor, and one with a copper
outer conductor). The titanium version was tested up to 1 MW (1 ms), both at
room temperature and at 100 K. The design of this window, and the results of
the high power tests are presented in this paper.
