Current Status of the CHIP-TRAP Penning trap mass spectrometer at CM

POSTER

Abstract

At Central Michigan University (CMU) we developing the CMU High Precision Penning trap (CHIP-TRAP) for precise mass measurements on stable and long-lived isotopes. The CHIP-TRAP apparatus includes a laser ablation source (LAS) and a Penning ion trap source (PIT) to produce ions from solid and gaseous samples, respectively. Ions from the LAS and PIT are transported along the beamline to a multi-reflection time-of-flight mass separator (MR-TOF-MS) that is used to remove contaminant ions from the beam before it is sent to the Penning trap. The CHIP-TRAP Penning trap system features two hyperbolic precision measurement traps for simultaneous cyclotron frequency comparisons and a cylindrical capture trap for contaminant ion identification and elimination. All three traps are in a 12 T magnetic field and maintained at 4 K using a pulse tube cryocooler. This presentation will cover the latest developments in the design, construction, and testing of the ion sources, beamline, and cryocooler in the CHIP-TRAP project. It will provide updates on the overall progress of the project, including the assembly, fabrication, and commissioning of the MR-TOF-MS and capture trap.
