Title: Design and characterization of Ion sources for CHIP-TRAP

Abstract

At Central Michigan University, we are developing a high-precision Penning trap mass spectrometer (CHIP-TRAP) for precise mass measurements with stable and long-lived isotopes. Ions will be produced using external ion sources and then transported to the Penning trap at low energy using electrostatic ion optics. Ion sources that will be utilized with CHIP-TRAP include a laser ablation ion source (LAS) that has already been commissioned, and a low current Penning ion trap (PIT) source that is currently being developed. The LAS enables ion production from solid targets via ablation and ionization with a high-powered laser pulse. The PIT source is a novel Penning ionization gauge (PIG) type source, consisting of a 0.55 T NdFeB ring magnet, cylindrical Penning trap, and low current thermal electron emitter that enables ion production via electron impact ionization of gaseous samples. For both ion sources, small bunches of ~100 – 1000 ions can be produced from a minimal sample of source material. Finally, the ion bunches are then transported along the CHIP-TRAP beamline, where time-of-flight mass filtering can be performed before they are captured in the CHIP-TRAP Penning traps.

Measurements and computational analysis of the natural decay of ¹⁷⁶Lu

Journal Article Quarati, F. G. A. ; Bollen, G. ; Dorenbos, P. ; ... - Physical Review. C

Background: Mainly because of its long half-life and despite its scientific relevance, spectroscopic measurements of 176Lu forbidden β decays are very limited and lack formulation of shape factors. A direct precise measurement of its Q value is also presently unreported. In addition, the description of forbidden decays provides interesting challenges for nuclear theory. The comparison of precise experimental results with theoretical calculations for these decays can help to test underlying models and can aid the interpretation of data from other experiments. Purpose: Perform the first precision measurements of 176Luβ-decay spectra and attempt the observation of its electron capture decays, asmore »« less

Investigation of the potential ultralow Q-value β-decay candidates ⁸⁹Sr and ¹³⁹Ba using Penning trap mass spectrometry

Journal Article Sandler, R. ; Bollen, G. ; Gamage, N. D. ; ... - Physical Review C

Background: Ultralow Q-value β decays are interesting processes to study with potential applications to nuclear β-decay theory and neutrino physics. While a number of potential ultralow Q-value β-decay candidates exist, improved mass measurements are necessary to determine which of these are energetically allowed. Purpose: To perform precise atomic mass measurements of ⁸⁹Y and ¹³⁹La. Use these new measurements along with the precisely known atomic masses of ⁸⁹Sr and ¹³⁹Ba and nuclear energy level data for ⁸⁹Y and ¹³⁹La to determine if there could be an ultralow Q-value decay branch in the β decay of ⁸⁹Sr → ⁸⁹Y or ¹³⁹Ba →more »« less

Mass measurement of ⁵¹Fe for the determination of the ⁵¹Fe($p, γ$) ⁵²Co reaction rate

Journal Article Ong, W. -J. ; Valverde, A. A. ; Brodeur, M. ; ... - Physical Review C

Background: The ⁵¹Fe(p, γ) ⁵²Co reaction lies along the main rp-process path leading up to the ⁵⁶Ni waiting point. The uncertainty in the reaction Q value, which determines the equilibrium between the forward protoncapture and reverse photodisintegration ⁵²Co(γ,p)⁵¹Fe reaction, contributes to considerable uncertainty in the reaction rate in the temperature range of interest for Type I x-ray bursts and thus to an ≈10% uncertainty in burst ashes lighter than A = 56. Purpose: With a recent Penning trap mass measurement of ⁵²Co reducing the uncertainty on its mass to 6.6 keV [Nesterenko et al., J. Phys. G 44, 065103 (2017)],more »« less

Precision Tests of the Electroweak Interaction using Trapped Atoms and Ions

Technical Report Melconian, Daniel George

The objective of the proposed research is to study fundamental aspects of the electroweak interaction via precision measurements in beta decay to test our current understanding of fundamental particles and forces as contained in the so-called "Standard Model" of particle physics. By comparing elegant experiments to rigorous theoretical predictions, we will either confirm the Standard Model to a higher degree and rule out models which seek to extend it, or find evidence of new physics and help guide theorists in developing the New Standard Model.
