Penning-Trap Mass Measurements of the Neutron-Rich K and Ca Isotopes: Resurgence of the N = 28 Shell Strength
A. Lapierre, M. Brodeur, T. Brunner +9
We present Penning-trap mass measurements of neutron-rich 44,47-50K and 49,50Ca isotopes carried out at the TITAN facility at TRIUMF-ISAC. The 44K mass measurement was performed wi…
First experimental determination of the charge radius of Rb and its application in tests of the unitarity of the CKM matrix
E. Mané, A. Voss, J. A. Behr +9
Collinear-laser spectroscopy with bunched-beams technique was used for the study of neutron deficient Rb isotopes, out to Rb () at TRIUMF. The measured hyperfine cou…
First Use of High Charge States for Mass Measurements of Short-lived Nuclides in a Penning Trap
S. Ettenauer, M. C. Simon, A. T. Gallant +17
Penning trap mass measurements of short-lived nuclides have been performed for the first time with highly-charged ions (HCI), using the TITAN facility at TRIUMF. Compared to singly…
A large Bradbury Nielsen ion gate with flexible wire spacing based on photo-etched stainless steel grids and its characterization applying symmetric and asymmetric potentials
T. Brunner, A. R. Mueller, K. O'Sullivan +9
Bradbury Nielsen gates are well known devices used to switch ion beams and are typically applied in mass or mobility spectrometers for separating beam constituents by their differe…
TITAN's Digital RFQ Ion Beam Cooler and Buncher, Operation and Performance
T. Brunner, M. J. Smith, M. Brodeur +12
We present a description of the Radio Frequency Quadrupole (RFQ) ion trap built as part of the TITAN facility. It consists of a gas-filled, segmented, linear Paul trap and is the f…
First direct mass-measurement of the two-neutron halo nucleus 6He and improved mass for the four-neutron halo 8He
M. Brodeur, T. Brunner, C. Champagne +11
The first direct mass-measurement of He has been performed with the TITAN Penning trap mass spectrometer at the ISAC facility. In addition, the mass of He was determine…
