  We present characterization results of a neutron Anger camera based on a
lithium-6 loaded cerium activated silicate glass scintillator (33.3 x 33.3 x 1
mm3) and an array of 64 silicon photomultipliers. Reconstruction of the
scintillation events is performed with a statistical method, implemented on a
graphics processing unit (GPU). We demonstrate that the light response model of
the detector can be obtained from flood irradiation calibration data using an
unsupervised iterative procedure. The useful field of view is 28 x 28 mm2. The
spatial resolution measured at 2.5 A neutron beam is better than 0.6 mm FWHM
and the energy resolution at the neutron peak is 11%.
