TI - Reduction of the Beam Jitter at the PIP2IT Test Accelerator J2 - Proc. of HB2021, Batavia, IL, USA, 04-08 October 2021 CY - Batavia, IL, USA T2 - ICFA ABDW on High-Intensity and High-Brightness Hadron Beams T3 - 64 LA - english AB - Analysis of the beam position monitor (BPM) signals at the H⁻ test linear accelerator PIP2IT showed that a large portion of the signals scatter comes from the beam jitter. BPM position measurements of the jitter modes were compared with beam motion responses to perturbations excited by driving various beamline parameters in a low frequency sinusoidal manner. The main contributor to the jitter was found to be a low frequency noise in the input reference to the ion source high voltage (HV) power supply. Filtering the HV power supply reference signal decreased the rms scatter in BPM readings by a factor of 2-3.
