Iterative Learning Control (ILC) is a technique for adaptive feed-forward control of electro-mechanical plant that either performs programmed periodic behavior or rejects quasi-periodic disturbances. For example, ILC can suppress particle-beam RF-loa

The stability and convergence of an Iterative Learning Controller (ILC) may be assessed either by directly iterating the equations for a variety of inputs, or by finding the eigenvalues of the iterated system, or by forming the Z-transform and applyi

Before AI and neural nets, the excitement was about iterative learning control (ILC): the idea to train robots to perform repetitive tasks or train a system to reject quasi-periodic disturbances. The excitement waned after the discovery of "learning

The radiation pressure inside an RF cavity resonator, resulting from the Lorentz force, couples the fundamental electromagnetic mode to the mechanical modes and may lead to static and dynamic ponderomotive instability. The analysis for generator driv

Beam-beam interactions are a limiting factor in the planned high luminosity (HL) upgrade to the Large Hadron Collider (HL-LHC). Over the two main interaction regions of the LHC, a particle experiences two head-on and over a hundred long-range beam-be

This paper is concerned with finding operations consistent with the absolute minimum emittance growth. The system is an RF bucket containing a bunch of hadrons in a synchrotron; and the operation performed is to sweep the RF phase. As a result, the b

The currently installed configuration of TRIUMF’s superconducting electron linac (e-linac) can produce an electron beam up to 30MeV and 10mA. Low beam power commissioning of the segment spanning the electron gun to high energy dump took place in su

The weak-strong model subjects the test particle in the weak beam to transverse impulses from the strong beam, resulting in betatron tune shifts. We give analytic formulae for small amplitude and asymptotic shifts for three cases: short-range, long-r

The commissioning of the Advanced Rare Isotope Electron Linac (ARIEL) facility at TRIUMF is underway. The 30 MeV e-linac has successfully been commissioned to 100 W, and to further increase the power to 1 kW the beam loss monitor system (BLM) for fas
