Synchrophasotron, an accelerator built in Dubna in 1957, has become the biggest and the most powerful for his time. Its magnet weighs 36000 tons and is registered in the Guinness Book of Records as the heaviest in the world. It had been working till 2002 and by now in its basement a new accelerator, Nuclotron, has been built.
Welcome to the territory of the Joint Institute of Nuclear Research.

The model of synchrophasotron
The structure of synchrophasotron, nuclotron works on the same principle
For protons acceleration a huge amount of energy is required.
Nuclotron was built in 1992 and its operating console looks more innovative.
Nuclotron doesn’t work permanently, there made 2 sessions a year lasting for about a month
The building of the synchrophasotron has a circular shape and it is already surrounded by auxiliary structures.

Acceleration starts in the linear accelerator, the power is so high that sometimes lightning strikes right in this room

The diameter of the synchrophasotron is 60 meters. It consists of 4 huge magnets where 2 cars can easily pass each other (5 meters high and 7 meters wide).
The magnet has such dimensions because the beam in the synchrophasotron is weak-focusing and kept inside the vacuum chamber 2m x 40cm and the magnet itself serves to keep the beam inside the ring.
When the synchrophasotron was built Vladimir Wechsler, a famous academician, told about it: “Few thoughts – much iron”. The rest of his life he devoted to the development of new methods of acceleration. Many of his ideas start to be practised only now.
The USSR was so proud of the synchrophasotron. At that time it was one of the symbols of Russian power. Many presidents and prime ministers came to Dubna to see this miracle.
Now the synchrophasotron is almost unmounted. In the building there remained only the magnet yoke. They plan to build a new accelerator.
These cool lights are on when the synchrophasotron works.
Near the synchrophasotron is a segment of nuclotron. Dimensions difference is enormous!
Input particle velocity is 30 thousand km per sec, output velocity is 300 thousand km per sec!
Cryogenic system cools the magnets to the temperature 516F

Lots of devices inside
And some doors afterall …
