WebJun 29, 2024 · Assuming that the distribution is in Gaussian form, the RMS bunch length could be calculated from full width half maximum of the distribution divided by the factor of 2.3548. By substituting the calculated RMS bunch length to Eq. , the new harmonic voltage and the new potential could be found. Then, we achieved the new longitudinal distribution. WebApr 11, 2024 · To remove noise from a repetitive signal the waveform averaging function was enabled and the measured bunch shape was an average of 200 waveforms of the bunches. We recorded the full width at half maximum (FWHM) of the bunch length and assumed the bunch has a Gaussian distribution, therefore a specific sigma (root-mean …
