Enhancing the mass resolving power of FRIB's proposed high-voltage MR-ToF mass separator and spectrometer: addressing non-ideal conditions
Christian Michael Ireland, Franziska Maria Maier, Einstein Dhayal +3
Multi-reflection time-of-flight mass separators and spectrometers (MR-ToF MSs) are indispensable tools at radioactive ion beam (RIB) facilities. These electrostatic ion beam traps…
The mass of Sn and Bayesian extrapolations to the proton drip line
Christian M. Ireland, Georg Bollen, Scott E. Campbell +23
The favorable energy configurations of nuclei at magic numbers of neutrons and protons are fundamental for understanding the evolution of nuclear structure. The ${Z=50}…
A high-voltage MR-ToF mass spectrometer and separator for the study of exotic isotopes at FRIB
F. M. Maier, C. M. Ireland, G. Bollen +7
The Facility for Rare Isotope Beams (FRIB) delivers a wide variety of rare isotopes as fast, stopped, or reaccelerated beams to enable forefront research in nuclear structure, astr…
High-precision Penning trap mass measurements of neutron-rich chlorine isotopes at the N=28 shell closure
H. Erington, G. Bollen, G. Dykstra +9
Although it is known that the spherical shell closure erodes, the strength of the closure with decreasing proton number is an open question in nuclear structure. In t…
Exploring Isospin Symmetry Breaking in Exotic Nuclei: High-Precision Mass Measurement of 23Si and Shell-Model Calculations of T = 5/2 Nuclei
F. M. Maier, G. Bollen, B. A. Brown +9
We present a high-precision mass measurement of the proton-rich nucleus 23Si, performed with the LEBIT Penning trap at the Facility for Rare Isotope Beams (FRIB) utilizing the time…
High-precision mass measurement of Sn restores smoothness of the mass surface
C. M. Ireland, F. M. Maier, G. Bollen +20
As a step towards the ultimate goal of a high-precision mass measurement of doubly-magic Sn, the mass of Sn was measured at the Low Energy Beam and Ion Trap (LEBIT)…
