Industrial Application Experiments on the Neutron Imaging Instrument DINGO

Publication date: 2017 Source:Physics Procedia, Volume 88 Author(s): Ulf Garbe, Yogita Ahuja, Ralph Ibrahim, Huijun Li, Laurie Aldridge, Filomena Salvemini, Anna Ziara Paradowska The new neutron radiography / tomography / imaging instrument DINGO is operational since October 2014 to support the area of neutron imaging research at ANSTO. The instrument is designed for a diverse community in areas like defense, industrial, cultural heritage and archaeology applications. In the field of industrial application it provides a useful tool for studying cracking and defects in concrete or other structural material. Since being operational we gathered experience with industrial applications and commercial customers demanding beam time on DINGO. The instrument is a high flux facility with is 5.3 × 107 [n/(cm2s)] (confirmed by gold foil activation) for an L/D of approximately 500 at HB-2. A special feature of DINGO is the in-pile collimator position in front of the main shutter at HB-2. The collimator offers two pinholes with a possible L/D of 500 and 1000. A secondary collimator separates the two beams by blocking one and positions another aperture for the other beam. The neutron beam size can be adjusted to the sample size from 50 × 50 mm2 to 200 × 200 mm2 with a resulting pixel size from 27μm to ∼100μm. The whole instrument operates in two different positions, one for high resolution and one for high speed. We would like to present our first experience with commercial ...
