In-beam hyperfine spectroscopy of antihydrogen, hydrogen and deuterium

E. Widmann

The ASACUSA collaboration is developing a polarized beam of antihydrogen atoms to precisely determine the ground-state hyperfine structure for studies of CPT and Lorentz invariance…

Pole position of measured in reactions

PARC E31 Collaboration, S. Aikawa, S. Ajimura +74

We measured a set of , , and invariant mass spectra below and above the mass threshold in -induced reactions on deuteron. We deduced th…

Upgrade of ASACUSA's Antihydrogen Detector

V. Kraxberger, C. Amsler, H. Breuker +35

The goal of the ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) CUSP experiment at CERN's Antiproton Decelerator is to measure the ground state hyperfine splitt…

Cyclotron cooling to cryogenic temperature in a Penning-Malmberg trap with a large solid angle acceptance

C. Amsler, H. Breuker, S. Chesnevskaya +35

Magnetized nonneutral plasma composed of electrons or positrons couples to the local microwave environment via cyclotron radiation. The equilibrium plasma temperature depends on th…
