T2K

The T2K experiment is a second generation long-baseline neutrino-oscillation experiment to study the nature of neutrinos. A neutrino beam is generated in Tokai, Japan and shot towards the Kamiomande detector 295km away.

STFC Technology are involved with aspects of Remote Handling management, The Near detector, Baffle and Beamline remote seals, and the Target.

The 1m long graphite target requires a mechanical support that also allows the high purity helium cooling gas to circulate at very high speed around it. There are tight space restrictions of only a mm or so, and since it is a high radiation area, reliability is paramount. Thorough CFD analysis has been carried out as part of the STFC mechanical design, and has proved that the cooling will be effective.
