Description
The Beam Position Monitors (BPMs), the primary tuning diagnostics for the Proton Storage Ring (PSR) at the Los Alamos Neutron Science Center (LANSCE), recently underwent an upgrade to their data acquisition system. Whereas the previous system relied on a multiplexed architecture, the new system provides independent readbacks for each BPM and incorporates beam phase measurements. In parallel, the beam current modulation at the beginning of the pulse was transferred from a deflector to a chopper, enabling the delivery of a single pilot minipulse to the PSR on every pulse. This enhancement allows continuous, online monitoring of PSR optics parameters. We present a new tuning software package, RingTune, which integrates multi stream diagnostic data with an online model to provide real time feedback for the Central Control Room and the development environment that simulates the PSR response.
