Delivery of TMCP Coldbox to the European Spallation Source

The target moderator Cryoplant TMCP Coldbox reached its destination at the European Spallation Source ESS in Lund, Sweden on 19 September after a trip through Europe.

The coldbox weighs 40 tonnes with a diameter of 3.5 m and a length of 10 m. This makes it the largest helium refrigeration system in the world in this temperature range. It delivers 30 kW of cooling power at 15-20K, which serves to absorb the heat that results when the elementary particles hit the target.

The coldbox will be installed next to the Accelerator Coldbox delivered last year.
