Oral invited talk

The Isotope Separator and ACcelerator (ISAC) facility at TRIUMF supplies both stable and rare isotope beams for a variety of nuclear astrophysics experiments. One of these, the Detector of Recoils And Gammas Of Nuclear reactions (DRAGON), investigates reaction rates of astrophysical processes via radiative capture measurements. Currently, rare isotope beams delivered to DRAGON are manually...

The Isotope Separation On-Line (ISOL) technique has enabled advances in many fields spanning in nuclear, atomic, molecular, solid-state and medical physics by producing radioisotopes at facilities like CERN ISOLDE and the emerging ISOL@MYRRHA. Tuning these facilities is a complex task that requires manual intervention by experienced operators, a process that is often time-consuming due to the...

115. Automated RI beam focusing and centering for BigRIPS Separator

Yohei Shimizu (RIKEN Nishina Center for Accelerator-Based Science)

2025-10-23, 1:50 p.m.

Isotope production, target, and ion source techniques

Oral contributed talk

Efficient production of radioactive isotope (RI) beams is critical for advancing nuclear physics research, and the superconducting in-flight separator BigRIPS has been a key component in this effort since 2007. To maximize user beam time and achieve optimal scientific outcomes, we have continuously refined technologies related to RI-beam separation and particle identification analysis. Key...

160. Development of automatic beam tuning system for high intensity heavy ion beams at RIBF

Machine Learning and AI

Oral invited talk

In general, accelerator facilities are controlled by a huge number of parameters. The RIKEN RI Beam Factory (RIBF), a heavy-ion accelerator complex consisting of several cyclotrons and Linacs, is controlled or influenced by more than 600 parameters, including environmental factors. To optimize these parameters more efficiently and accurately, we are attempting to implement Bayesian...

21. The new MRTOF mass spectrometer at HIAF facility

Chaoyi FU (The university of Hong Kong)

Ion optics and spectrometers

Oral contributed talk

A new state-of-the-art multi-reflection time-of-flight mass spectrometer, referred to as HKU-MRTOF, has been constructed in the HKU-KEK collaboration. It aims to operate for nuclear mass measurements of multinucleon transfer (MNT) products at the HIAF facility, through coupling to a cryogenic gas cell. It is part of a low-energy station for making full use of the low-energy heavy-ion beams...
