Description
The ARGITU RFQ at ESS-Bilbao is a 352.2 MHz, 4-vane RFQ that will
accelerate protons from 45 keV to 3.0 MeV. The RF power comes from a
modulator/klystron by rectangular waveguides that end in coaxial lines
that are finished by the two loop power couplers. The couplers are made
of copper and no brazing has been used in their production. For this
reason, the vacuum/air window is made of PEEK material attached by
mechanical pressure to the copper structure. For the initial stages of
the ARGITU RFQ, the duty cycle will not rise above 1%, so these
couplers were designed with no active cooling. This paper summarizes the conditioning setup and focuses on the RF, thermal and multipacting simulations used to define safe high-power conditioning limits.
