Description
The gas-filled in-flight separator RITU at Jyväskylä, Finland, has
been recently re-commissioned. A new focal plane instrumentation has
been constructed and set-up at the RITU focal plane. It shares the
same dimensions with the MARA focal plane which enables the use of
same detectors and vacuum parts in both. Alongside the instrumentation
the RITU recommissioning results and the brief operational principle
will be presented.
The in-flight recoil mass spectrometer MARA has been used successfully
over many years. The main objective has been the study of the neutron
deficient nuclei close to the proton drip line and nuclei around the
N=Z line. Several new isotopes and proton emitters have been
identified in the decay studies at the focal plane and new nuclear
structure information extracted via in-beam studies utilizing MARA and
the Jurogam Ge-detector array. A new scintillator detector, Tuike, has
been taken in use at the focal plane to improve the identification of
weakly produced isospin-multiplet members under study by
detecting high-energy betas. In addition to the brief overview
of these type of MARA experiments, the description of charge plunger set
up, able to probe lifetimes of highly converted transitions in heavy
nuclei, will be given.
