The PANDORA (Particle Analyzer Neutron Detector Of Real-time Acquisition) system is a neutron detector based on plastic scintillator coupled to digital readout.[1] This system is designed for study of unstable nuclei by (p,n) reaction using inverse kinematics. As it is well known, the detection of low energy neutrons is difficult due to the gamma events background. A new type of scintillation material provides different response to neutrons and gamma rays, so we can select neutron events by analyzing the pulse shape. This pulse shape analyses can be done by a digital data acquisition (DAQ) system so that the gamma background can be greatly suppressed.

Comparing to ref. 1, newer version scintillators with better neutron-gamma discrimination performance are applied. In addition, the DAQ software was modified to suit our configuration and some bugs were fixed. The system was commissioned in a 6He(p,n)6Li reaction experiment and the system shows a good performance on neutron-gamma separation.

In this poster, we will show some results of the neutron-gamma separation and some preliminary results of our (p,n) reaction experiment.
