Low-energy and in-flight separators

Submitted Oral

A new separator, MARA (Mass Analyzing Recoil Apparatus) [1], has recently been constructed at Jyväskylä University ACCLAB. MARA is a vacuum-mode double focusing mass separator. The ion-optical configuration is QQQDEDM. MARA went through an extensive commissioning program during 2016 and already during 2017 MARA was used in spectroscopic studies at and beyond the proton drip line. In these...

Low-energy and in-flight separators

Submitted Oral

In 2017 the first set of radioactive ion beams (RIBs) was obtained from the new in-flight fragment separator ACCULINNA-2 [1] operating at the primary beam line of the U-400M cyclotron [2]. Observed RIB characteristics (intensity, purity, beam spots in all focal planes) were in agreement with estimations. The new separator provides high quality secondary beams and it opens new opportunities for...

The energy of the RI beam is one of the most important parameter for reaction studies. At RIKEN RI beam factory (RIBF), the energy around 200 MeV/u is easily available because the primary-beam energy is 345 MeV/u. Spectrometers and beam-line detectors are optimized to this energy region. On the other hand, for the transfer reaction, the multi-nucleon transfer reaction, and the fusion reaction,...

Low-energy and in-flight separators

Submitted Oral

Recently, the Berkeley Gas-filled Separator (BGS) at the Lawrence Berkeley National Laboratory (LBNL) was coupled to a new mass analyzer, FIONA. The goal of BGS+FIONA is to provide a M/deltaM separation of ~300 and transport nuclear reaction products to a shielded detector station on the tens of milliseconds timescale. These upgrades will allow for direct A and Z identification of ii) new...

21. Initial Operating Experience with the Recoil Mass Spectrometer EMMA

Dr Barry Davids (TRIUMF)

Low-energy and in-flight separators

Invited

EMMA is a recoil mass spectrometer recently installed in the ISAC-II experimental hall of TRIUMF. It is designed to separate the heavy products of nuclear reactions from the beam and to disperse the recoils according to their mass/charge ratios. The results of commissioning tests with an alpha source and both stable and radioactive ion beams to determine the dispersion, resolving power, and...
