Trapping and cooling of ions contributed to many areas in physics, ranging from particle physics to astro-physics. In this talk, I will show the features, first results, and future plans with the new Refrigerated Electron-Beam Ion Trap (R-EBIT) at AlbaNova.
R-EBIT is a Penning trap-like system that can produce and trap highly-charged ions, presently up to Uranium 82+. Due to its structure radiation can be observed from the trap with high resolution instruments. This gives opportunities to study the recombination with electrons in the trap. Knowledge of this process is important in astrophysics and fusion research. One experiment aims to measure with high precision the Lamb-shift in highly-charged Kr ions. It was planned to transfer SMILETRAP, a spectrometer to measure ion masses at 10-10 accuracy, to R-EBIT, for determinations of Q values of b decay schemes and for a QED test by measuring the bound state electron g-factor. In a different set-up we exploit the excellent emittance of the extracted ions from R-EBIT for characterization of nano-structures by ion transport. Experiments with R-EBIT at the DESY Free Electron Laser (VUV- and X-FEL) are in preparation.
