Invited Oral Presentation

Antihydrogen - the bound state of an antiproton and a positron - is of great interest for tests of fundamental symmetries which compare antimatter to ordinary matter. In the ALPHA experiment these exotic atoms are confined in a magnetic minimum with a lifetime of many hours, limited only by annihilations on background gas in the vacuum chamber. This enables high precision measurements which...

49. The SIS100 laser cooling facility at FAIR (MOC2)

COOL'25

Invited Oral Presentation

The heavy-ion synchrotron SIS100 is (at) the heart of the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It is designed to accelerate intense beams of heavy highly charged ions up to relativistic velocities and to deliver them to unique physics experiments, such as those planned by the APPA/SPARC collaboration. In order to cool these extreme ion beams, bunched beam...

12. High power optical cavities for ion beam cooling at the SPS Gamma Factory Proof of principle experiment (MOC3)

COOL'25

Invited Oral Presentation

The Gamma Factory is a project which aims providing unprecedented rates of photons in a wide range of energy, possibly up to 400MeV. It relies on resonant atomic excitation of partially stripped ions accelerated at high energies with state of the art high power laser systems enhanced in optical resonators. In a proof of principle experiment at the CERN SPS, a demonstration of the viability of...
