Description
A cavity beam position monitor (cBPM) developed by
CEA Saclay was installed at the end of the Accelerator Test
Facility (ATF) linac to evaluate the combined performance
of the monitor and its associated signal processing system.
The setup incorporates a down-conversion architecture inspired
by Royal Holloway, University of London (RHUL),
and employs a digital down-conversion (DDC) algorithm
to extract beam position. This configuration enables highsensitivity
measurements of the transverse beam position.
Preliminary results confirm successful signal acquisition
and a clear position-dependent response, validating the integrated
performance of the cBPM, analogue electronics,
and digital processing chain. The results underscore the
necessity of reliable local oscillator (LO) phase-locking to
ensure precise position determination.
