The lab aims to identify the origin of the highest-energy particles that rain down from space.
AboutAbout the lab
Where do cosmic rays come from?
The High Energy Cosmic Ray Division (Sako Lab) investigates the origin of the high-energy cosmic rays that rain down from space.
Through the Telescope Array experiment and the ALPACA experiment, the lab observes "air showers," a phenomenon that cosmic rays produce in the atmosphere.
To study the ultra-high-energy elementary particle reactions that these observations require, the lab also conducts experiments using the LHC and RHIC accelerators.
The research is carried out in collaboration with Professor Ogio and Associate Professor Kawata of the Institute for Cosmic Ray Research, and the lab also conducts joint research with other universities.
Key terms
- Cosmic ray
- A high-energy particle that rains down on Earth from space
- Air shower
- A phenomenon in which a cosmic ray collides with an atomic nucleus in the atmosphere, causing a cascade of many particles to descend like an avalanche
- Collider
- A device that accelerates particles to nearly the speed of light and collides them head-on to create high-energy reactions

ResearchResearch themes
The lab studies cosmic rays. By combining observations of air showers with particle reaction experiments using accelerators, it works to uncover the origin of high-energy cosmic rays.
*Illustrative imageTelescope Array Experiment
Using detectors spread across a desert in the United States, the lab searches for the sources of extremely high-energy cosmic rays.
*Illustrative imageALPACA Experiment
Using an air shower detector array located in the Andes mountains of South America, the lab searches for objects within our Galaxy that accelerate particles up to PeV energies.
*Illustrative imageMeasuring Cosmic Ray Reactions with Accelerators
Using the LHC and RHIC colliders, the lab measures particle production in the very forward region of high-energy hadron reactions, which is needed for air shower research.
*Illustrative imageAir Shower Simulation Code
As a key link connecting cosmic, particle, and observational research, the lab is developing COSMOS, an air shower simulation code.
