Heat Advisory
Summer temperatures in Japan can be extremely high, with daytime temperatures often exceeding 35°C (95°F).
If you are traveling from the nearest station, we recommend taking a taxi or local bus instead of walking whenever possible.
A sun umbrella (parasol) is provided in your conference bag to help protect you from the strong sunlight.
Please drink plenty of water and take appropriate precautions against the heat.

You can find many hotels in the Ikebukuro area on hotel booking websites such as Expedia and Hotels.com. From Ikebukuro station to Wako-shi station, it takes 12 minutes by the Tobu-Tojo line or the Metro Fukutoshin line, as shown in the Map. If you have any problems in finding your hotels, please contact the LOC.
Lab tour:
RIBF tour is scheduled on Tuesday evening (Sep. 1).
We invite you to RIBF tour at RIKEN Wako campus. In the tour, we will visit mainly two facilities: Cyclotron (SRC) and Fragment Separators (BigRIPS). 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.
The Radioactive Isotope Beam Factory (RIBF) is a facility generating unstable nuclei of all elements up to uranium and studying their properties. 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 most powerful 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 world-highest 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.
