The tandem Penning trap mass spectrometer ISOLTRAP has been set up at the on-line mass separator ISOLDE at CERN/Geneva for accurate mass measurements of short-lived nuclei with T 1 2 ≥ 1 s.Abstract:
The tandem Penning trap mass spectrometer ISOLTRAP has been set up at the on-line mass separator ISOLDE at CERN/Geneva for accurate mass measurements of short-lived nuclei with T 1 2 ≥ 1 s . The mass measurement is performed via the determination of the cyclotron frequency of an ion in a magnetic field. The design of the spectrometer matches the particular requirements for on-line mass measurements on short-lived isotopes. With the ISOLTRAP spectrometer masses of more than 70 radioactive nuclei have so far been determined with resolving powers exceeding one million and an accuracy of typically 10−7.read more

High-accuracy mass spectrometry with stored ions
TL;DR: The mass of an atom, and its inherent connection with the atomic and nuclear binding energy is a fundamental property, a unique fingerprint of the atomic nucleus as mentioned in this paper, and the importance of its mass ranges from verification of nuclear models to a test of the Standard Model, in particular with regard to the weak interaction and the unitarity of the Cabibbo-Kobayashi-Maskawa quark mixing matrix.

Recent trends in the determination of nuclear masses
TL;DR: The mass of the nucleus has been of capital importance not only for various aspects of nuclear physics, but also for other branches of physics, notably weak-interaction studies and astrophysics as mentioned in this paper.

Geonium theory: Physics of a single electron or ion in a Penning trap
Lowell S. Brown,Gerald Gabrielse +1 more
TL;DR: In this paper, the theory of a single charged particle in a Penning trap is reviewed, beginning with simple first-order orbits and progressively dealing with small corrections which must be considered owing to the experimental precision that is being achieved.
