Synchrophasotron And Nuclotron

Synchrophasotron And Nuclotron 1

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.

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.

Near the synchrophasotron is a segment of nuclotron. Dimensions difference is enormous!

  1. 1stish

    This machine looks very high tech ( for the 1950’s)
    I think they were training that kid to run it. Nice lack of safety equipment.

  2. Most impressive! Considering this was designed and built before superconducting magents, this physics research device must have required awe-inspiring amounts of electricity to operate back in its heyday. Big physics research usually results in awesome big facilities.

  3. Only just noticed that the nuclotron is being serviced by one of the cheapest, most unreliable air compressors on the market. All that efort an work could be wasted. You have been warned.

    • The results from those tests might actually (indirectly mostly) give quite some benefits in research in other area’s, medicine being one of them.

      Research isn’t useless simple because the results themselves don’t offer direct practical uses.

  4. After all that money and material is spent on that monster machine, they usually end up with a lot of nothing useless information. Better to spend it on hospitals to care for people.

  5. Very nice, but totally outdated. I am pretty sure so is the Nuclotron. Have a look at the LHC: http://en.wikipedia.org/wiki/Large_Hadron_Collider

  6. Soviet emphasis on science and education produced this marvel. Meanwhile, in the US the cult of celebrity and money produces exploitation and inequality.

  7. A. Bunka here. I would just like to intersect one poynt, here, one ting. I hope you Russkies don’t go and melt or blow up something big again. The world marvels at Soviet science, especially at Chernobyl. Still glows, doesn’t it? Yeah, it will for a long time too. I understand the Russkies are building a refrigerator the size of Rhode Island to keep it from burning through too… whereever the hell the other side of the world is over there. The Russkies could build a flying dinosaur, the Ekranoplan, but they couldn’t make enough toliet paper and cigarettes for everybody that’s why it fell.

    • That’s exactly what we, Russians, love most: doing something big, monumental, so that everyone else will be frightened at the very thought of what could happen! 😉

      It’s almost as fun as the famous “Kuzkina Mat'”!

    • 300km/s _is_ the speed of light. As an approximation to the speed of the output beam that would apply to any sufficiently high-energy particle accelerator – give the particles enough energy and they will move as near to the speed of light as makes no difference… Would be interesting to know what the actual energy is though.

      Love that patch panel, too 😀

  8. just noticed, check out the pic with the yellow “traffic lite” status lamps. The lamp next to it is a compact flourecent (energy saving) Maybe they’re worried about the power bills?

  9. too many people with hurt ego on the blog – humour is good, but when I feel desperation behind attempt to say smth. molish and humiliating about Russia- it is not fun anymore – relax and enjoy photos of smth. you would have never seen anywhere else…Remember how Walter Croncite reported about USSR launch of first man (Gagarin) into space? – he started his news report with the phrase which discreditated american national ckarackter more then KKK could ever do – he said: “America have been deeply heart today….”(it is about the greatest technological and scientific achievement in human history and only because it was not AMERICAN!)- and then he continued with the story of first human in space…it was this atitude which was shame of USA, not the fact that they were not first in this or that…by the way in USSR american succes of landing on the Moon was reported as great achievent and was shown on TV without no any bitter comments …so don’t cover your country with shame again, americans, you have a great country and science and technology – don’t spoil impression with envious atitude and pathetic attemps to gloat…
