Description
An significant part of the upgrade of the Dubna Radiactive Ion Beams facility is the replacement of the ACCULINNA fragment separator with a new high acceptance device - the ACCULINNA-2. The project of a new in-flight facility for low energy 30-60 AMeV primary beams with 3 ≤ Z ≤ 36 has been started in 2011. The new device is destined to add considerably to the studies of drip-line nuclei performed with the use of variety of direct reactions known to be distinctive to the 15 – 50 AMeV exotic secondary RIBs. An overview of the design, construction and commissioning studies of the ACCULINNA-2 device will be presented.
Secondary beam profiles as well as production rates were measured for 15N (49.7 AMeV) primary beam and Be (2 mm) target. Example dE-ToF identification spectra and calculated beam purity for 6He 31.5 AMeV and 12Be 39.4 AMeV as a main components of secondary beams will be demonstrated. Measured isotope yields agrees with LISE++ simulations. Future upgrades of ACCULINNA 2 setup (zero degree spectrometer, RF-kicker) and prospects of new experiments achievable in next years are presented.
