Bare Argon Nuclei Slowed by Four Orders of Magnitude
HITRAP carried accelerator-made highly charged ions into a Penning trap and electron-cooled them there for the first time.
Summary
HITRAP carried accelerator-made highly charged ions into a Penning trap and electron-cooled them there for the first time.
TU Darmstadt and GSI researchers stripped argon atoms of all electrons, produced the ions at roughly 30% of light speed, then reduced their kinetic energy by about 10,000 before storage in HITRAP's Penning trap. They also observed electron cooling of highly charged ions inside such a trap for the first time. The milestone establishes infrastructure for precision measurements with heavy ions; it is an enabling result rather than a new measurement of fundamental physics.
Why it matters
HITRAP carried accelerator-made highly charged ions into a Penning trap and electron-cooled them there for the first time.
