If you haveany problems in finding your hotels please contact with the LOC.

Lab tour:We invite you to Lab tour at RIKEN Wako campus. In the tour, we willvisit two facilities: (1) Cyclotron (SRC) and Fragment Separators(BigRIPS) (2) Compact Neutron Source, RANS and RANSII. In the tour,
we ask you to divide several groups, but all groups will visit both facilities.
Your group is marked on your name card.
(1) SRC and BigRIPS at RIBF
The Radioactive Isotope Beam Factory (RIBF) is a facility generating
unstable nuclei of all elements up to uranium and studying theirproperties. The RIBF is characterized by the fact that it is a multistage
accelerator complex, which is generally not seen elsewhere in the world.
The final-stage accelerator, the Superconducting Ring Cyclotron (SRC),
is the first of a kind and is the largest (weighing 8,300 tons) and mostpowerful in the world. The accelerated high intensity heavy ion beams(~10kW) are injected to Fragment Separator called BigRIPS to generate an RI beam for all elements up to uranium with the worldhighest intensity. These beams are provided to several experimental systems such as SHARAQ, SAMURAI, ZeroDegree to study
nuclear physics and reveal the evolution of the universe. In the tour, we show the SRC and BigRIPS.

(2) RANS / RANSIIRIKEN is promoting the maintenance and advanced development ofcompact neutron source measurement systems with the aim of using“neutrons anytime, anywhere.” As of 2023, two RIKEN acceleratordriven compact neutron systems (RANS), RANS and RANS-II, are inconstant operation, and RANS-III is currently under development at
RIKEN Wako. In these systems, high power proton beams (~ a few pμA)
are injected to Beryllium and lithium target to generate neutrons. In thetour, we show RANS / RANSII.
You will have the chance to visit our experiment facility and research
environment etc.
