Description
A significant part of the upgrade of the Dubna Radioactive Ion Beams facility was putting in operation a new high acceptance device - the ACCULINNA-2 fragment separator, http://flerovlab.jinr.ru/accullina-ii/. It’s the new in-flight facility for operating with low energy 30-60 AMeV primary beams with 3 ≤ Z ≤ 36 delivered by U-400M cyclotron. The new separator provides high quality secondary beams what opened new opportunities for experiments with RIBs in the intermediate energy range 10÷50 AMeV. Since 2018 a few experimental studies have been carried out at the ACCULINNA-2 setup [1-4]. Recent experimental results on 6,7H, 7He will be presented. A new experimental program with RIBs at the FLNR starting in 2024 and potential of using additional equipment as radio frequency filter, zero angle spectrometer, cryogenic tritium target and new detectors development will be discussed.
