Description

The ISOLTRAP setup is a high-precision mass spectrometer designed to measure the masses of short-lived, exotic radionuclides far from the valley of stability. Utilizing both multi-reflection time-of-flight (MR-ToF) and Penning-trap mass spectrometry, ISOLTRAP performs precise absolute and relative mass measurements. Converting these measured masses into nuclear binding energies (via the mass-energy equivalence) provides critical insights into the underlying nuclear forces and structures.

This contribution will present the current status of ISOLTRAP and highlight recent technical developments, such as the implementation of a second linear Paul trap to rebunch mass-selected ion beams, the addition of a temperature-stabilization system for the MR-ToF mass spectrometer, and improvements of our laser ablation ion source for the production of reference ions. This years beamtime results will also be shown, focusing on the first mass measurement of neutron-deficient $^{96}$Cd in the vicinity of the doubly-magic $^{100}$Sn, as well as the first mass measurement of the neutron-rich $^{49}$Ar that was enabled by the new mass selective retrapping.
