Low Power RF

The RF laboratory covers different areas related to the diverse disciplines of the RF accelerator technologies.

SCOPE

The Low Power RF consists of the following main parts:

Electromagnetic design and simulations

Electromagnetic design of passive components is made by means of 3-D full-wave electromagnetic field software Ansys HFSS and Comsol. Resonant cavities, power couplers, other passive components in rectangular waveguide technology (Magic-T, phase shifter…) have been designed.

Magic T design

RF measurements

The RF lab is equipped with a high-quality instrumentation to carry out a thoroughly low power RF characterization of passive and active components operating in CW or pulse mode, including also a specific instrumentation for phase and amplitude low noise measurements.

Test set up

Cavity characterization

A specific test bench is available for the resonant cavities characterization including the bead pull test. A procedure with a pillbox cavity let calibrate the beads used in the bead pull test, to eliminate the error introduced by the bead parameters obtaining a more accurate accelerating field profile measurements.

Electronics and control

The electronic designs and process control are required for different RF applications or measurements such us: timing box, low noise RF generators, control and automatization of measurements procedures or laboratory instruments or any other components.
