ASQ instruments
ASQ is responsible for the operation and development of selected SINQ instruments,
primarily dedicated to materials research: NEUTRA, ICON and POLDI.
-
NEUTRA
The instrument NEUTRA (Neutron Transmission Radiography) was the startup facility for
neutron imaging at the SINQ and is nowadays still one of the top instruments in the field
for neutron imaging in the world. It provides a large and homogenous thermal neutron beam for many
scientific and industrial applications. A complementary X-ray tube installation is used for
comparison studies (XTRA option).
-
ICON
A beam of cold neutrons is used in ICON in a similar way than in NEUTRA for all
imaging purposes. However, some advanced methods and options are provided now in addition to the standard
setup: micro-tomography, energy-selective imaging (using a turbine selector) and phase contrast imaging.
The facility is equipped with state-of-the-art imaging systems and a user-friendly infrastructure.
-
POLDI
POLDI (Pulse-OverLap DIffractometer) is a unique time-of-flight neutron diffractometer and is hosted by the
group .
The main applications of POLDI are the determination of residual stresses and the study of deformation mechanisms
in engineering materials.
