Extended State Observer for Localized Fault Awareness in RF Accelerating Structures
Luke S. Baker, Sungil Kwon, Kwame Jyamfi +5
An observer framework is presented for robust regulation of RF cavity fields and localized identification of disturbances in RF systems. A standard cavity field observer is augment…
Disturbance Observer Application for the Compensation of the Phase Drift of the LANSCE DTL LINAC Solid State Power Amplifier
Sungil Kwon, M. S. Barrueta, L. Castellano +4
The front end of Los Alamos Neutron Science Center (LANSCE) linear accelerator uses four 201.25-MHz Drift-Tube Linacs (DTLs) to accelerate the H+ and H- beams to 100 MeV. Three of…
MATLAB Scripts for RF Commissioning at the LANSCE LINAC
Sungil Kwon, A. Archuleta, L. Castellano +4
The linear accelerator (LINAC) at the Los Alamos Neu-tron Science Center (LANSCE) consists of Pre-buncher, Main-Buncher, low-energy beam transport (LEBT), four 201.25-MHz Drift Tub…
LANSCE Digital Low Level RF Upgrade
P. Van Rooy, M. Prokop, S. Kwon +4
Incremental upgrades of the legacy low level RF (LLRF) equipment-50 years for the Los Alamos Neutron Science Center (LANSCE)-involves challenges and problems not seen with new and…
