Development and test of a fast neutron camera — •Christoph Günther, Nina Höflich, Oliver Pooth, Christian Teichrib, and Simon Weingarten — III. Physikalisches Institut B, RWTH Aachen University, D-52056 Aachen
We are developing a prototype of a scintillator based camera for fast neutron radiography. The camera consists of 4 × 4 pixels with a size of 5 mm× 5 mm per pixel. Each pixel consists of a stilbene crystal whose scintillation light is read out by an SiPM. As a neutron source we use an 241Am/9Be source that emits neutrons with energies up to 11 MeV. So far, optimization studies have been carried out with one pixel in order to achieve a good gamma-neutron discrimination and to maximize the number of detected neutrons.
In this talk the further development of the camera and first measurements with the 4×4 pixel array are presented. To be able to capture images of larger size, measurements with a XY-table will be carried out.
