N2 - High resolution imaging of fast neutrons combined with energy spectroscopy is required in a variety of applications, ranging from Fast Neutron Radiography and Tomography, nuclear material monitoring, to solar and atmospheric physics Over the last decade several groups have been developing fast detectors based on particle tracking using scintillating plastic fibers or capillary tubes filled with liquid scintillator, mainly in order to determine the direction of the incident neutron and for high resolution imaging [1-5] Our principal interest is Fast Neutron Resonance Radiography (FNRR) [8], which requires detectors with the following properties: high neutron efficiency (> 10%), large area or long linear arrays for high resolution radiography of voluminous objects, sub-mm position resolution capabilities, neutron spectroscopy, insensitivity to gamma-rays The imaging neutron detectors we have developed for FNRR to-date [9,10] perform fast neutron spectroscopy by the method of measuring neutron time-of flight (TOF) TOF methods require operating with a nanosecond-pulsed neutron source, such as a particle accelerator In this paper we describe development of a micro-capillary bundle detector filled with liquid scintillator, that will permit high resolution imaging and medium-quality energy spectroscopy of non-pulsed fast neutron sources, such as CW accelerators, isotopic neutron sources or reactor beams
