§ 45. Mr. Haleasked the Lord Privy Seal whether he is aware that at the recent official conference on high energy nuclear physics in Moscow British physicists were shown a high energy synchrocyclotron giving beams of protons of 680 Mev and a new proton synchroton containing 36,000 tons of steel and were informed of an even larger one under construction; and what steps he proposes to take to enable Great Britain to participate in the development of high energy physics.
§ Mr. R. A. ButlerI am aware of the large facilities which the Soviet Union is creating for fundamental nuclear research. Her Majesty's Government, as a member of the European Council for Nuclear Research, are collaborating in the building of a 600 Mev synchrocyclotron and a 25,000 Mev proton synchrotron of the most advanced design at present known at the High Energy Physics Laboratory which is being built up in Geneva.
