Session 5 - Instrumentation for radioactive ion beam experiments
- Hideyuki Sakai (RIKEN)
The SAMURAI spectrometer has been designed for various types of experimental studies using high intense beams of exotic nuclei provided by the BigRIPS fragment separator at RI Beam Factory (RIBF). SAMURAI consists of a large-gap superconducting dipole magnet equipped with heavy ion detectors, a large-volume neutron detector array NEBULA, and proton detectors. Since the construction was...
The $(p,n)$ reactions in inverse kinematics provide uniqe tool to study the spin-isospin responses of radioactive nuclei, including their giant resonances, in a wide excitation energy region. In particular, high luminosity can be achieved using thick hydrogen target without losing information on recoil neutron momentum applied for the missing mass reconstruction [1]. As a side effect in this...
The OEDO system was proposed to produce focused slow-down radioactive-ion (RI) beams in RIBF, and has been installed in the High-Resolution Beamline (HRB) in the end of fiscal year 2016.
Generally, the momentum dispersive focal plane has a strong correlation property between the pass point and the timing of the beam. The OEDO system was designed to tune separately energy degrading and beam...
The Wako nuclear science center (WNSC), a collaboration between RIKEN and KEK, has directly measured the masses of more than 80 isotopes. We have recently performed the first mass measurements of several Md isotopes [1] along with other rare species such as Ac/Ra isotopes [2] using a multi-reflection time-of-flight spectrograph (MRTOF-MS) coupled to the gas-filled recoil ion separator GARIS-II...
