Broadband FFT Method for Betatron Tune Measurements in the Acceleration Ramp at COSY-Jülich
نویسندگان
چکیده
A method for measurement of betatron tune without the need for feedback-driven excitation has been developed at COSY. A bandlimited broadband noise source was used for beam excitation. The transverse beam position oscillation was then bunch-synchronously sampled and digitized with a high resolution ADC. The Fourier transform of the acquired data represents immediately the betatron tune. A functional description of the measurement system and the evaluation of the measured data are presented.

Tune Measurement for the Cern Proton Synchrotron Booster Rings Using Dsp in Vme
The CERN PS Booster (PSB) consists of 4 superposed rings supplied with protons from a 50 MeV Linac. The proton beam is then accelerated to 1 GeV and sent either to the 26 GeV Proton Synchrotron (PS) or to the ISOLDE facility. This is carried out in a multi-cycle mode every 1.2 s. For high-intensity beams, the working-point in the tune diagram needs to be changed considerably during acceleration...
متن کاملThe Light Scalar Mesons a0/f0(980) at COSY-Jülich
The light scalar mesons a0/ f0(980) are being investigated at COSY-Jülich by detecting the strong decays into KK̄ and πη /ππ as well as radiative decays into vector mesons. Selected results are discussed with emphasis on recent measurements at the ANKE and WASA spectrometers.
متن کاملThe RHIC Tune Measurement System
Each of the four fractional betatron tunes of RHIC (two planes, two rings) is measured with a transverse beam kicker and dedicated beam position monitor (BPM). A 15kV pulse is generated by a fast FET switch, passed through a stripline kicker, attenuated, and returned to the instrumentation control room (ICR) for monitoring. When pulsed at 3kV, the four-meter long kicker gives a gold beam at inj...
متن کاملGas Scintillation Beam Profile Monitor at Cosy Jülich *
The interaction of ion beams with the surrounding residual gas leads to photon emission by the excited residual gas atoms and molecules. These photons in the visible spectrum range can be used to monitor the transverse beam profile. We therefore use a multichannel photomultiplier (PMT) together with an optical imaging system. Measurements at COSY synchrotron of the Forschungszentrum Jülich are ...
متن کاملAn Inductive Pick-up for Beam Position and Current Measurements
D D The fractional part of the betatron tune for a circular accelerator can be measured by observing beam oscillations on a position pick-up. In frequency domain the betatron frequency is seen as sidebands on either side of the revolution harmonics. Usually beam signal pulses from the pick-up are very short with respect to the revolution period, resulting in a broadband spectrum. Classical tune...
