61. The ISOLDE Improvement Program, and what will happen in the hall

Erwin Siesling (CERN)

03/12/2025, 11:10

Invited (In person)

The ISOLDE Long Shutdown starts at the end of December and will last two years to accomodate the replacement of the ISOLDE dumps as well as the upgrade of the BTY line for 2GeV proton beam, the refurbishement of HIE ISOLDE Cryo Module 1 and many other improvements, consolidation and maintenance to the facility and the experimental setups.
This talk will give you an overview and timeline of...

81. Recent mass measurements and developments including the first application of mass-selective re-trapping at ISOLTRAP

Daniel Lange (Max Planck Society (DE))

Invited (In person)

The ISOLTRAP mass spectrometer [1], located at ISOLDE/CERN, performs high-precision mass measurements of short-lived, exotic nuclides far from stability. These measurements provide direct access to nuclear binding energies, which reflect the underlying nuclear interactions, thereby enabling studies in nuclear structure and nuclear astrophysics, among others.
For this, the ISOLTRAP mass...

Recent Monte Carlo Shell Model (MCSM) calculations made by T. Togashi et. al. [Phys. Rev. Lett. 121, 062501 (2018)] attempt to account for discrepancies observed between measurements and previous theoretical calculations of the reduced transition probability B(E2;$2^{+}_{1}->0^{+}_{1}$) in the neutron deficient Sn isotopes. One of the predictions of the MCSM calculation is that a shape change...

The Standard Model (SM) has proven to be a successful theory describing three of the four fundamental interactions. However, some open questions remain and motivate precise measurements to search for evidence of physics Beyond the SM predictions. For instance, the measurement of the shape of the β energy spectrum can be used to search for...

26. The PI-LIST: High-resolution crossed-beams laser spectroscopy inside the ISOLDE laser ion source

Asar A H Jaradat (The University of Manchester (GB))

Submitted oral (In person)

Laser resonance ionization spectroscopy in the ion source coupled directly to the isotope
production target has been proven to be a highly sensitive tool for nuclear structure investigations on
isotopes with low production and extraction yields [1]. While the efficiency of this technique is
unrivalled, the spectral resolution is ultimately limited by Doppler broadening. At the ion source...
