6. FIONA ToF: a Time-of-Flight detector for studies of superheavy elements at Berkeley Lab

Marilena Lykiardopoulou (Lawrence Berkeley National Lab)

2025-10-21, 3:30 p.m.

Low-energy and in-flight separators

Oral invited talk

Superheavy elements tend to decay mostly by alpha decay and spontaneous fission and their detection and study often relies on the detection of the alpha particles and the fission products using silicon detectors. In addition, half-lives can be deduced through the timestamps of implantation and decay events. This is possible due to the fact that after production, the ions have 10s of MeV of...

161. KISS1.5 to reveal the origin of heavy-element synthesis

Yoshikazu HIRAYAMA (KEK WNSC)

2025-10-21, 4:00 p.m.

Ion traps and laser techniques

Oral invited talk

To reveal the origin of heavy-element synthesis in the universe, studying nuclear properties such as half-life, atomic mass, and nuclear structure is essential. Particularly, the properties of heavy-element nuclei located in unreachable regions, specifically those in the vicinity of the neutron magic number N = 126 and neutron-rich actinide nuclei, are crucial for understanding the r-process....

70. Development and application of a dispersion-matched ion-optical mode of the SRC and BigRIPS system for high-resolution missing-mass spectroscopy experiments with primary beams

Ion optics and spectrometers

Oral contributed talk

The high-intensity beams available at RIBF provide new opportunities for precision missing-mass spectroscopy with reactions using primary ion beams. One of the essential techniques to achieve excellent missing-mass resolution is the realization of dispersion-matched ion optics, which minimizes the effects of the momentum spread of the incident beams. We have developed a dispersion-matched...

15. What's special about the ARIEL HRS?

Richard Baartman (TRIUMF)

2025-10-21, 4:50 p.m.

Ion optics and spectrometers

Oral contributed talk

High resolution separators have a reputation as being unstable and difficult to tune. The ARIEL HRS has been designed to overcome these difficult characteristics. To do this, it has two unique features. (1) The matching system into and out of the HRS acts as both a matcher and a dispersion-magnifier. (2) The aberration correction is not performed using a conventional multipole. Instead, the...

23. Recent advances of the S3-Low Energy Branch

Sarina Geldhof (GANIL)

2025-10-21, 5:10 p.m.

Ion traps and laser techniques

Oral contributed talk

The SPIRAL2 facility of GANIL will significantly extend the capability to study short-lived nuclei by producing beams of rare isotopes at unprecedented intensities. The SPIRAL2-LINAC coupled with the Super Separator Spectrometer (S$^3$) recoil separator will facilitate the production of neutron-deficient nuclei close to the proton dripline as well as super heavy nuclei via fusion-evaporation...
