Description
ELISA (Elastic and Inelastic Scattering Array) is a unique experimental setup in Europe, located at the GELINA (Geel Electron Linear Accelerator) facility of the EC-JRC (European Commission - Joint Research Centre), in Geel, Belgium. The setup has been developed for measuring neutron scattering differential cross sections in time-of-flight (ToF) experiments [1, 2].
The original ELISA spectrometer consists of 32 organic liquid scintillators for the detection of the scattered neutrons, from which half of the detectors have EJ301 (NE-213 equivalent) as scintillation liquid, while the rest have EJ315 (C6D6). A 235U fission chamber is used for the measurement of the incoming neutron flux. As of recently, an additional arm with eight 6Li-glass detectors has been added, in an effort to expand the low-energy neutron detection limit below 1 MeV.
To test and validate the normal operation of the new components of the ELISA setup, new measurements with a natural carbon target are being performed. The performance of the 6Li-glass detectors with respect to gamma and neutron detection will be presented, together with a first estimation of the upgrade.
