Description
The ROmanian array for SPectroscopy in HEavy ion REactions (ROSPHERE) has been designed as a multi-detector setup dedicated to γ-ray spectroscopy studies at the Bucharest 9 MV Tandem accelerator. Consisting of up to 25 detectors (either Compton suppressed HPGe detectors, fast LaBr$_3$(Ce) scintillator detectors) together with a state of the art plunger device, ROSPHERE is a powerful tool for lifetime measurements using the Doppler Shift Attenuation Method (DSAM), Recoil Distance Doppler Shift (RDDS) and the in-beam Fast Electronic Scintillation Timing (FEST) methods.
ROSPHERE can be arranged, since 2021, in a new configuration consisting up to 25 ELIGANT/ELIADE 3”x3” LaBr$_3$(Ce)/CeBr scintillators together with DSSSD detectors for particle identification, resulting in a high efficiency, medium resolution spectrometer.
The presentation will include an overview of the 9MV Tandem accelerator of IFIN-HH and the on-going experimental programme together with the present status of the ROSPHERE array, recent physics highlights and future developments.
