Target Station High Level Functions
Proton beam transport hallTarget monolith Utilities block
High bayActive cells
• Generate neutrons via the spallation process using protons received from the accelerator
• Moderate neutrons to energies in the range of 0.1 to 330 meV(corresponding wavelengths of 30 to 0.5 Å)
• Direct neutrons to neutron scattering instruments
• Safe, reliable operation with high availability
