Abstract
TITAN (TRIUMF's Ion Trap for Atomic and Nuclear science) at TRIUMF's rare isotope beam facility ISAC is an advanced Penning trap based mass spectrometer dedicated to precise and accurate mass determinations. An overview of TITAN, the mea- surement technique and a highlight of recent mass measurements of the short-lived nu- clides important to the nuclear structure program at TITAN are presented.
Highlights
Accurate and precise mass values of atomic nuclides are important for many disciplines in physics including the study of nuclear structure [1], the study of the production of elements in stellar nucleosynthesis [2], and the test of fundamental symmetries, such as the conserved vector current (CVC) hypothesis in super allowed β decays [3]
The TITAN Penning trap mass spectrometer is coupled to the rare-isotope-beam facility ISAC [13]
The short-lived ions delivered from ISAC [13] or the stable ions delivered from an off-line ion source are transported to the helium gas-filled radio-frequency quadrupole (RFQ) cooler and buncher [28]
Summary
Accurate and precise mass values of atomic nuclides are important for many disciplines in physics including the study of nuclear structure [1], the study of the production of elements in stellar nucleosynthesis [2], and the test of fundamental symmetries, such as the conserved vector current (CVC) hypothesis in super allowed β decays [3]. The coupling of Penning traps to rare-isotope-beam facilities has revolutionized the field of mass spectrometry of exotic nuclides. The TITAN Penning trap mass spectrometer is coupled to the rare-isotope-beam facility ISAC [13]. During the recent years TITAN has provided accurate and precise mass values of atomic nuclides to study nuclear structure [14, 18,19,20,21,22,23,24,25], nuclear astrophysics [26], the weak interaction [17], and neutrino physics [27]
