Secondary spectrometer

ThALES is expected to be used both for traditional TAS investigations of the inelastic response and its evolution with external parameters at a selected point of reciprocal space and for mapping of extended areas of the reciprocal space in search of inelastic signal.

To provide optimum conditions for both types of experiments ThALES will provide two interchangeable analyzer-detector systems:

• conventional single analyzer/detector unit for classical three-axis experiments (Fig.1)
• multiplexed analyzer/detector system for mapping inelastic response over larger phase space areas (Fig.2)
