Permanent magnet Penning trap for heavy ion storage
نویسندگان
چکیده
The construction and operation of a Penning ion trap is described in which the trapping field is provided by a cladded NdFeB permanent magnet. Studies with atomic ions show that the trap can provide stable ion confinement for extended periods ~*100 ms! making it suitable for use in a wide variety of applications. Use of the trap to measure the lifetime of excited SF6 * and C7F14 * ions produced in Rydberg atom collisions is briefly discussed. © 2002 American Institute of Physics. @DOI: 10.1063/1.1490411#

Nondissociative low energy electron attachment to C2Cl4 :C2Cl4
The lifetimes of long-lived parent anions formed by nondissociative electron attachment to C2Cl4 are investigated using Rydberg atom techniques. The ions are created through electron transfer in collisions with K(np) Rydberg atoms and their lifetimes are measured using both time-of-flight techniques and a permanent magnet Penning trap designed specifically for heavy ion storage. The data show t...
متن کاملA Penning trap for laser spectroscopy of cold, trapped, highly-charged ions
The HITRAP facility will soon provide highly charged ions (HCI) at very low energies and offers unique possibilities for laser spectroscopy of hydrogenlike and lithiumlike heavy ions. We are currently developing a dedicated Penning trap and laser system for this task in close collaboration with the Imperial College London, and the TU Darmstadt. This trap will be operated with a Helmholtztype su...
متن کاملElectron capture from H2 to highly charged Th and Xe ions trapped at center-of-mass energies near 6 eV
Ions with charge states as high as 801 , produced in the Lawrence Livermore National Laboratory electron beam ion trap were extracted and transferred to a Penning ion trap ~RETRAP!. RETRAP was operated at cryogenic temperature in the field of a superconducting magnet. The stored low-energy ions collided occasionally with H2 molecules in the ultrahigh-vacuum environment of the trap, capturing on...
متن کاملDesign of a Compact All-permanent Magnet Ecr Ion Source Injector for Rea at the Msu Nscl
The design of a compact all-permanent magnet electron cyclotron resonance (ECR) ion source injector for the ReAccelerator Facility (ReA) at the Michigan State University (MSU) National Superconducting Cyclotron Laboratory (NSCL) is currently being carried out. The ECR ion source injector will augment the electron beam ion trap (EBIT) charge breeder as an off-line stable ion beam injector for th...
متن کاملRotationally induced Penning ionization of ultracold pho- toassociated helium dimers
– We have studied photoassociation of metastable 2S1 helium atoms near the 2 S1-2 P2asymptote by both ion detection in a magneto-optical trap and trap-loss measurements in a magnetic trap. A detailed comparison between the results of the two experiments gives insight into the mechanism of the Penning ionization process. We have identified four series of resonances corresponding to vibrational m...
