Butterfly Moderator Manufacturing Completed at Jülich
The ESS Target Division has announced that manufacturing of all three Butterfly V2 cold moderators was completed in December.Read More
The spallation process at ESS will take place when the accelerated proton beam hits the tungsten bricks of the 4.9-tonne target wheel, producing unprecedented neutron brightness for scientific experiments across multiple disciplines.
The design of target system components has a direct impact on the number of neutrons that can be generated, and is therefore of utmost importance for the future scientific capabilities of the ESS facility.
The first step in this process is production of high-energy neutrons through a spallation process involving proton beam interaction with a tungsten target. The fast, high-energy neutrons released during the spallation process at ESS will be slowed down to suitable energies for experiments, and then delivered to the instruments through beam ports. Key features of the Target Station are the target itself, the neutron moderator and reflector system, and the neutron beam extraction system.
