Description
A new neutron imaging instrument will be built to support the area of neutron imaging research (neutron radiography/tomography) at ANSTO. The instrument will be designed for an international user community and for routine quality control for archaeology, geology, defence, industrial, mining, space and aircraft applications. It is also a useful tool for assessing hidden features from corroded samples and magnetic imaging of core drill sample to understand human impact in different areas of Australia[2]. The instrument is fully installed and will be operational by end of 2013. The designated instrument position for DINGO [1] is the beam port HB-2 in the reactor hall. The estimated flux for an L/D of approximately 500 at HB-2 is calculated by Mcstas simulation in a range of 4.75 * 107 [n/cm2s]. A special feature of DINGO is the in-pile collimator place 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 will separate the two beams and block one. The whole instrument will operate in two different positions, one for high resolution and one for high speed.
