Nuclear Data Experimental Terminal

May 28, 2025

In 2011, the Chinese Academy of Sciences (CAS) launched a Strategic Priority Research Program “the Future Advanced Nuclear Fission Energy—ADS Transmutation System.” The nuclear data at intermediate and at higher energies based on nuclear reaction information is fundamental requirement for spallation target design. Based on Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR), the Nuclear Data Experimental Terminal (CSRm-ET2) was established. The nuclear data measurement facility for ADS spallation target has been constructed, which provides a very important platform for the experimental measurements of spallation reactions at CSRm-ET2. The facility consists of water-bath neutron activation measurement setup, light charged particles spectrometer, neutron time-of-flight spectrometer and PISA detection system.

The experimental studies for intermediate and high nuclear reaction, ion beam radiation and ion beam photograph can be carried out at CSRm-ET2. Several experiments about spallation neutron energy spectrum measurements, neutronic performance studies for spallation target and proton beam photograph have been performed.
