ColdQuanta Photo Challenge Answer

June 1, 2017

 

This is one of ColdQuanta’s earlier generation ion pumps. It was built to test performance tolerances to asymmetry and alignment of electric and magnetic fields.  The results of the tests were used to influence design decisions for later incarnations of the integrated ion pump in systems such as channel cells as well as validating their utility for our IP efforts. This picture was taken after the important testing was complete since pressures in the milli-torr or worse are needed to visualize the penning cloud in this manner.
