Abstract
Abstract
Bunch-by-bunch (BbB) technique, which allows accelerator
physicists to monitor beam information on finer timescales, is an
efficient tool for studying longitudinal and transverse beam
dynamics. However, the real-time measurement in BbB technique can
only monitor one beam parameter, thus focusing only on the
longitudinal phase or transverse positions of bunches. Therefore, to
solve this issue, we put forward a one-time sampling method (OSM) to
evaluate the longitudinal phase and transverse positions of bunches
simultaneously, taking as one way of the real-time measurement for
BbB three-dimensional (3D) positions. And we carried out related
experiments in Hefei Light Source II and Shanghai Synchrotron
Radiation Facility. As a result, experiments show that OSM obtains
12 μm of x-direction resolution, 10 μm of
y-direction resolution, 0.57 ps of z-direction resolution at
Hefei Light Source II, and 10 μm of x-direction resolution,
10 μm of y-direction resolution, 0.35 ps of z-direction
resolution at Shanghai Synchrotron Radiation Facility. All these
experimental results reveal that OSM is feasible to measure the BbB
3D positions.
