Multiplexing Spectrometer CAMEA

The Continuous Angle Multiple Energy Analysis (CAMEA) spectrometer is optimised for an efficient and detailed mapping of excitations under extreme conditions. The instrument is configured to maximise the energy-resolved detection of in-plane scattered neutrons. Eight radially mounted units consist of eight analyser segments each, covering 60˚ of the horizontal scattering plane at final energies ranging from 3.2 to 5 meV. This allows to map a large (q, w)-area in a single acquisition scan, while being compatible with complex sample environments such as high pressure devises, cryomagnets and dilution refrigerators.  CAMEA is located at the cold-neutron guide RNR13 of the SINQ spallation source and is, therefore, optimised for low-energy (∆E ≤ 13 meV) magnetic correlations.

A detailed description of the instrument’s capabilities, how CAMEA data can be handled efficiently and links to scientific examples can be found in the menu on the left hand side. CAMEA proposals can be submitted trough duo.psi.ch, and the following document can help with an efficient planing of beam time. Please do not hesitate to contact us if further questions arise.
