Measurement of the time profile of a single-bunch electron beam with wireline pickup by considering the wake-field effect
Abstract
The effect of a wake-field generated by an electron beam passing through a linac beam exit window was studied experimentally, to establish the response of a beam monitor with a wireline pickup. To suppress the effect of the wake-field, a copper disk with a beam entrance-hole was placed in front of the pickup. A discussion of the frequency domain response for this monitor was also made, to corroborate the data of suppression of the effect. A considerable improvement in the time domain response was observed for a single-bunch electron beam from the linac at ISIR of Osaka University. A waveform with 50 ps rise time and 150 ps FWHM was obtained.
