Future Program of the BASE Experiment at the Antiproton Decelerator of CERN

Le résumé fourni par la source

This report outlines the future program of the BASE antiproton experiment at the Antiproton Decelerator (AD) facility of CERN. We describe methods and future developments to improve the precision of the antiproton-to-proton charge-to-mass ratio to the parts-per-trillion (p.p.t.) level and the precision of the antiproton magnetic moment to a level of 100 p.p.t. on the short term. Our proposal includes the application of phase sensitive detection techniques, the implementation of measurements on co-trapped particles, the development of more advanced Penning-trap systems, and the invention of a novel type of trap — a cooling trap. In order to further improve experimental precision beyond these limits, we will develop a transportable trap for antiprotons to move the particles out of the AD-facility. This will become necessary since accelerator operation imposes electrical and magnetic noise which makes high-precision Penning-trap measurements beyond the p.p.t. level impossible in the current location of BASE. We request additional offline laboratory space on the CERN campus in which a second high-precision Penning-trap experiment will be con- structed and operated. The transportable trap will supply this second exper- iment with antiprotons. In the new laboratory we will further advance our high-precision studies by applying classical measurement methods in calmer environment and by implementing quantum-logic inspired methods for sym- pathetic cooling and spin-state readout of single trapped antiprotons.
