Deep in the mountains of Japan, there is a scientific wonder rising silently: Hyper Kamiokande. This massive device, which emerged as a result of 20 years of meticulous preparation and engineering masterpiece, has the potential to reveal one of the greatest secrets of the universe. This structure, which was carefully planned and built over a long period of time, is 88 meters high and 69 meters wide.
University of Tokyo and the High Energy Accelerator Research Organization (KEK), is being implemented with the collaboration of scientists from more than 20 countries around the world. Why is this mysterious gigantic structure, exceeding scientific boundaries, built deep in the mountains in one of the deserted corners of Japan, and why do scientists endure this difficult journey?
The World’s Largest Neutrino Observatory: Hyper Kamiokande
Hyper Kamiokande in Japanthe world’s largest neutrino observatory is taking important steps towards becoming This $600 million scientific giant, to which scientists from 21 countries contributed, will be one of Japan’s construction marvels. Now, let’s move on to a scientific perspective on why this giant was built here.
The universe consists of quarks, bosons and one of the smallest particles. neutrinos It is full of subatomic particles such as Neutrinos are known as the mysterious travelers of the universe. Neutrinos can be described as particles emitted from billions of stars, which almost never interact with matter and pass silently through our bodies.
If we can solve the mystery of these ghostly beings, We can profoundly change our understanding of the universe. However, capturing the smallest building blocks of the universe is not an easy task.
Hyper Kamiokande A number of photodetectors being manufactured for use a variety of methods to detect neutrinos. One of these methods, other by colliding with particles at high speed is the study of the effects of the collision. The giant cylinder was built by carving deep into the mountain.
Drilling is expected to be completed in 2025
It took 9 months to bore a 2 kilometer tunnel using drilling and blasting techniques, and then concrete was sprayed to smooth the surface. The tunnel extends to the center of the dome to be built over the observatory. observatory, It is located 681 meters below the summit of the mountain and is reinforced with a steel cage to carry the weight of the rock on it.
The team blasted the rock to create a massive cavern for the observatory, providing the perfect environment for detecting neutrinos. The density of the rock provides the observatory with protection equivalent to being almost 1.7 kilometers below sea level, thus protecting it from cosmic rays and other radiation. Drilling is expected to be completed in 2025.
After the cave is covered with concrete, it will become the world’s largest water tank and 260 million liters of water will be filled into it. The water will be purified by purifying it with UV light and other methods. As neutrinos travel through water, they will collide with electrons and emit Cherenkov radiation, and this structure was built to observe tiny flashes of light.
