Study of beam envelope oscillations by measuring the beam transfer function with quadrupolar pick-up and kicker

A quadrupolar pick-up provides information on beam envelope oscillations. To enhance the signals we have used a quadrupolar kicker to excite these modes. In this way the incoherent Laslett tune shift can be directly measured. The tune shifts and spreads of a dense proton beam obtained at LEAR with e...

description A quadrupolar pick-up provides information on beam envelope oscillations. To enhance the signals we have used a quadrupolar kicker to excite these modes. In this way the incoherent Laslett tune shift can be directly measured. The tune shifts and spreads of a dense proton beam obtained at LEAR with electron cooling have been studied varying parameters like the number of particles and the cooling time constant. The effects of stop-band on beam distribution as well as on instabilities have been studied. The technique and the results of these measurements will be discussed.
