Lascar Isotopes examined during Summer 2013 93Sr, 95Sr, 93Rb, 106Mo, 106Tc, 134I-m, 134I-g, 142I, 147Cs, 148Cs, 146La-m, 146La-g, 148Ba, 149Ba, 150Ba, 162Sa, 162Eu, 164Eu, 165Gd

13. CPT Detector Upgrade Replacing current Channeltron detector with a position sensitive MCP Enables phase-imaging ion- cyclotron resonance (PI-ICR) measurements

14. PI-ICR Measurements Ions from the Penning trap The position of the ion in the trap is projected onto the MCP when ejected. The orbital frequency of the ion’s motion is calculated from the phase change over time. S. Eliseev et. al./Phys. Rev. Lett. 110 (2013) 082501
