ECHIDNA's the name of the new neutron High Resolution Powder Diffractometer at Australia's new research reactor OPAL, ANSTO. The instrument serves to determine the crystalline structures of materials using neutron radiation analogical to X-ray techniques. It operates with thermal neutrons. One of the main features's the array of 128 collimators and position sensitive detectors for rapid data acquisition. ECHIDNA allows for structure determinations, texture measurements and reciprocal space ma… (More on Echidna)
