A new record at BESSY II: ten million ions in an ion trap cooled for the first time to 7.4 K

Magnetic ground states of dimeric nickel cations spectroscopically ascertained

30-Nov-2016 - Previously it was only possible to cool down about one thousand ions to 7.5 K using buffer gas. However, a thousand ions are not nearly enough for spectroscopic analyses. The ion trap with this new method provides a new opportunity to use cryogenic X-ray spectroscopy to study the magnetism and ...

UCLA physicists' technique for cooling molecules may be a stepping stone to quantum computing

02-Apr-2013 - The next generation of computers promises far greater power and faster processing speeds than today's silicon-based based machines. These "quantum computers" — so called because they would harness the unique quantum mechanical properties of atomic particles — could draw their computing power from ...

With single laser pulses on single molecules

Physicists at MPQ succeed in resolving the internal dynamics of individual molecules using UV femtosecond laser pulses

14-Feb-2012 - Nowadays, large laser systems provide ultra-short light pulses of very high intensity which – in principle – allow the imaging of matter and its dynamics on atomic scales, down to a single molecule or a virus. However, current methods fall short in efficiency to overlap a target molecule in a ...

Setting out to discover new, long-lived elements

For the first time, 'ion traps' were used to measure super heavy elements
