Target
TEXT SIZE: A A A

The high-energy proton beam extracted from the accelerator bombards on the target to generate neutrons through spallation reaction. Tungsten is used as the target material with heavy water as the cooling media. The high-energy neutrons are then cooled down by moderator to become thermal or cold neutrons, which meet for the neutron scattering experiments.

For the CSNS target station design, the target team had chosen an all-horizontal target/moderator/reflector arrangement in 2009. The horizontal trolley that contains most of all the active components in a single assembly that can be easily retracted into the target remote handling cell. It also reduces the complexity of the shielding and reduces the need for overhead handling.
