Landau cavities at MAX II

Landau Cavities at Max Ii

Passive Landau cavities have been built, installed and taken into regular operation in the MAX II ring. The purpose of the Landau damping system is twofold: to decrease the energy spread of the beam induced by coupled bunch oscillations and to increase the Touschek life-time. The cavities are of the pillbox type operated at 1500 MHz, the third harmonic of the main RF. This paper describes the d...

Landau Cavities in Third Generation Synchrotron Light Sources

The new 3 generation synchrotron light sources coming up are designed for a small transverse emittance. But the small beam size gives a low Touschek lifetime and calls for good beam stability. In some storage rings higher harmonic cavities are installed for bunch lengthening to overcome the lifetime limitations. The higher harmonic cavities also induce Landau damping that improves the beam stab...

Cyclotron Cavities , Part Ii Draft

The following chapter is an extension and complement of the chapter titled: 'CYCLOTRON CAVITIES', written by C. Pagani (University of Milano and INFN, Milano, I). It will deal with cavity concepts deviating from conventional cyclotron cavities (Dees) treated in the previous lecture, which are mostly based on a λ/4 or λ/2 coaxial resonator design. Cavities differing from that design usually can ...

MAX II Device Handbook

Max at Seventeen

I have worked for many years on a computer environment for realizing works of live electronic music, which I named in honor of Max Mathews. Three currently supported computer programs—Max/MSP, Jmax, and Pd—can be considered as extended implementations of a common paradigm I'll refer to here as " Max. " The Max paradigm appears to be stable enough now that a printed description of it no longer r...
