According to different sources, there are several methods and instruments used to perform neutron cross-section measurements at a nuclear research reactor:

Neutron Activation and Accelerator Mass Spectrometry (AMS): This method involves the use of neutron activation in a nuclear research reactor and accelerator mass spectrometry (AMS). Combining two precise techniques has been used to measure the thermal neutron capture cross-section.

Neutron Total Cross-Sectional Spectrometer (NTOX): This is a technique for measuring neutron total cross-section. It is based on a multilayer fast fission chamber with 235 U and 238 U.

Neutron Reaction Rate Measurement: The neutron flux distribution in the research reactor can be determined by measuring the neutron reaction rate of Au wires and foils.

Time-of-flight (TOF) Method: This method is applied to cross-section measurements. It provides sufficient energy resolution to measure resonance energy cross sections typically up to ∼ 100 eV.

Direct Neutron Capture Measurements in Inverse Kinematics: This method is being developed to extend direct measurements towards shorter-lived radioactive nuclei.

Please note that these are general methods, and the specific method to be used can vary depending on the specific requirements of the experiment or research.
