Noninvasive 3D Field Mapping of Complex Static Electric Fields [PDF]

Physical Review Letters, 2019
Many upcoming experiments in antimatter research require low-energy antiproton beams. With a kinetic energy in the order of 100 keV, the standard magnetic components to control and focus the beams become less effective. Therefore, electrostatic components are being developed and installed in transfer lines and storage rings.
