Atomic Beam Measurement of the Potassium 39-41-42 Isotope Shift

Measurement of Beam-beam Tune-shift Parameter at Kekb

We have measured the coherent beam-beam tune shift at KEKB, an asymmetric double-ring electron/positron collider. The relationship between the tune shift and the beam-beam parameter is nonlinear, because the tunes are very close to a half integer. The estimated horizontal emittance is much larger than the calculated value, which is evidence of a dynamic effect due to the beam-beam interaction. ...

Calculation of Nonlinear Tune Shift Using Beam Position Measurement Results

The calculation of the nonlinear tune shift with amplitude based on the results of measurements and the linear lattice information is discussed. The tune shift is calculated based on a set of specific measurements and some extra information which is usually available, namely that about the size and particle distribution in the beam and the linear optics effect on the particles. The method to so...
