Description

Ranging from detecting a slow temperature rise to responding rapidly to
excessive current flow in the coupler bias high-voltage circuit, and up
to detecting stray RF signals, the Radio Frequency Protection Interlock
(RFPI) system is designed to monitor numerous cavity-related signals and
react within 100 µs - 1ms time to any observed violation of safety
margins. This contribution summarizes the current status of the design
and evaluation of a novel RFPI system developed for the Proton
Improvement Plan II (PIP-II) project at Fermilab. It presents an
overview of the system’s evolution—from the initial proof-of-concept
(PoC) prototype to the final design version prepared for the last stage
of evaluation before the mass-production campaign. The status of the
dedicated test-stand environment used for system verification is also
discussed
