14:40 → 14:50 Targets, Schedule and Physics

Speakers: Hanne Heylen (CERN), Isabel Frank (CERN), Matthias Alexander Grasser, Simon Thomas Stegemann (CERN)

Physics

On HRS, post-accelerated ¹⁰⁸Sn beams were sent to ISS to perform transfer reactions to study the evolution of nuclear structure towards the doubly magic ¹⁰⁰Sn nucleus. This was already the third experiment in a month focusing on this very interesting region of the nuclear chart. Everything went smoothly, both on the machine and experimental side, and the users went home happily.

Schedule

• 2.5 uA
• oflline operation of experiments during period in 2026 (electricity, pressured air, … )
• 25th of September. - HRS NMR probe
