The subject of this thesis is the control of singularly perturbed Markov and semi-Markov jump
linear systems, as well as a particular control problem in accelerator physics known as the …

Resistive wall instability is a serious problem in many light sources. An active transverse
feedback system (TFS) is required to operate the machine in a good condition when beam …

In PEP-II heavy beam loading along with a relatively long revolution period combine to
strongly drive lower coupled-bunch modes through interaction with the fundamental cavity …

The advanced photon source storage ring has several bunch fill patterns for user operation.
The hybrids fill pattern consists of a single bunch with a charge of 16 mA and a bunch train …

Heavy beam loading in PEP-II has driven the design of the low level RF system to contain
feedback loops similar to those used in proton rings. The RF feedback loops control …

The operation of a longitudinal multibunch damping system using digital signal processing
(DSP) techniques is shown via measurements from the Lawrence Berkeley Laboratory (LBL) …

ABSTRACT A transverse feedback system has been implemented and commissioned in the
SRRC storage ring to suppress transverse coupled-bunch oscillations of the electron beam …

As the intensity levels of the Fermilab Booster are pushed higher, it becomes necessary to
have greater control over beam instabilities. One way to control these instabilities is with …

A model of the RF feedback system for PEP-II has been developed to provide time-domain
simulation and frequency-domain analysis of the complete system. The model includes the …

Development of modern circular accelerators is nowadays focused on increasing energy
and intensity of the beam. For high current operation, the electromagnetic fields self …
