“…[2][3][4]) and the imaginary gamma-transition lattices [5,6], which are lattices designed to avoid transition crossing. The former is being operationally applied at the PS for example, while the lattice of the CERN Low Energy Antiproton Ring (LEAR) was an example of the latter technique [7]. Nowadays, several machines worldwide operate successfully through transition, among them the BNL Alternating Gradient Synchrotron (AGS) and the Relativistic Heavy Ion Collider (RHIC) [8][9][10][11], and the CERN Super Proton Synchrotron (SPS).…”

A novel non-adiabatic approach to transition crossing in a circular hadron accelerator

et al. 2021

Crossing the transition energy is always a delicate process, representing a potential source of strong perturbations of the dynamics of charged particle beams in a hadron circular accelerator. Since the first generation of multi-GeV rings, intense studies have been devoted to understanding the possible harmful mechanisms involved in transition crossing and to devise mitigation measures. Nowadays, several circular particle accelerators are successfully operating across the transition energy and this process is well mastered. In a completely different context, stable resonances of the traverse phase space have been proposed as new means of manipulating charged particle beams. While the original aim of such a proposal was multi-turn extraction from the CERN Proton Synchrotron to the Super Proton Synchrotron, many more applications have been proposed and studied in detail. In this paper, the two topics, i.e. transition crossing and stable resonances, have been brought together with the goal of providing a novel and non-adiabatic approach to perform a clean transition crossing. The idea presented here is that by judiciously using sextupoles and octupoles it is possible to generate stable islands of the horizontal phase space. These islands represent a second closed orbit whose properties can be selected independently of those of the standard, i.e. central, closed orbit. This provides a means of performing a non-adiabatic change of the transition energy experienced by the charged particles by displacing the beam between the two closed orbits.

“…Since 1980, CERN has conducted a low-energy antiproton program for precision CPT and gravity measurements, first with the Low Energy Antiproton Ring (LEAR) [2] and then with the Antiproton Decelerator (AD) [3]; a recent summary of the status of the experiments at the AD is provided, e.g., in Ref. [4].…”

Abstract. A detection scheme based on real-time measurement of antihydrogen annihilations during radiation injection is presented, which allows an efficient use of the trapped atoms for laser and microwave spectroscopy. The application of real-time detection of H annihilations to microwave spectroscopy, which yielded the first evidence of microwaveinduced spin-flip transitions in trapped antihydrogen [1], is reported.
