Rf Cavity Bpm's as Beam Angle and Beam Correlation Monitors*
It has been shown that high performance cavity BPM's are capable of accurate beam trajectory angle and beam ‘tilt’, (x-z or y-z correlation) measurements [1],[2]. Such a device will be very useful for the optimization of a variety of beamlines, such as high current linacs, bunch rotators and storage rings. The signal from a non-axial trajectory or a tilted beam is in quadrature to that observed...
متن کاملRobinson-type Criteria for Beam and Rf Cavity with Delayed, Voltage-proportional Feedback
We generalize the Robinson stability criteria, for a charged particle beam interacting with the radio-frequency cavity resonator that is responsible for accelerating it, to the case that the resonator is equipped with a delayed voltageproportional feedback.
متن کاملMeasurement of High Q RF Cavity Impedance with Beam
An inexpensive method to measure, with beam, the Rs and Q of narrow-band high order resonances in RF cavities was developed on SPEAR. The two main results of this study are: an improved operational stability of SPEAR the decision to keep the present cavities for the proposed SPEAR upgrade. SPEAR3 will be run initially at 200 mA, twice the present current. Just beyond the current threshold, and ...
متن کاملBeam Profile Measurement in MTA Beam Line for High Pressure RF Cavity Beam Test
Recent High Pressure RF (HPRF) cavity experiment at MuCool Test Area (MTA) has used 400 MeV Linac proton beam to study the beam loading effect. When the energetic proton beam passes through the cavity, it ionizes the inside gas and produces the electrons. These electrons consume RF power inside the cavity. Number of electrons produced per cm inside the cavity (at 950 psi Hydrogen gas) per incid...
متن کاملTransient Beam Loading in the Als Harmonic Rf System*
We report on the commissioning of a higher harmonic radiofrequency system at the Advanced Light Source, designed to improve the beam lifetime. We have achieved an increase above a factor of two in our best results up to now. Transient beam loading of the harmonic cavities, due to the unequal fill patterns, creates the greatest limitations on lifetime improvement. We also describe several intere...
