EBIS OPIG Station
(LEICF)


The ECR, Cryebis and various stand-alone sources comprise
the LEICF, found in the source area of the "new" lab.
 

Octopole Ion beam Guide (OPIG)

The octopole ion-beam guide (OPIG) technique is used in conjunction with the Cryogenic Electron Beam Ion Source (CRYEBIS), to facilitate the study of low energy collisions. An RF field applied to the OPIG confines the ions radial motion, but does not affect the motion along the beam axis. The OPIG is also floated on a DC potential in order to decelerate the projectile ion to the desired collision velocity.

The DePaola group has recently completed data-taking on charge exchange of multiply charged ions on He and H2.
