$A method for detailed simulations of neutron diffraction from ... - ESRF$

Other types of detectors PMF requires also 2D detectors (see pages 44, 50 and 59) and energy dispersive detector (see page 94). TEXAS/EXAFS requires also energy dispersive detector (see page 94) and a 2D detector for diffraction experiments (see page 48). 20
Differential spectroscopy in total fluorescence yield mode Project (Former BL) Application Circular Polarization Beamline (ID12) Polarization dependant spectroscopies in total fluorescence yield mode Aim of the detection system The aim of the detection system is to collect fluorescence photons in order to record absorption spectra and to obtain from them dichroic signals. Monochromatic beam Operating conditions and specifications Energy range: The energy ranges from 1.5 to 20 keV. Integration time: The integration time ranges from hundreds of seconds to milliseconds and will be shortened to a few nanoseconds for particular experiments. Energy resolution: Energy resolution is necessary only for some experiments, in order to suppress background coming from an element with absorption edge near the studied edge. This case is mentioned on page 94. Spatial resolution: Spatial resolution is not required. I0 diode If diodes Chopper Sample Efficiency: In order to avoid over-illumination of the sample (and of all beamline optical elements, that could compromise the stability of the measurement), the efficiency of the detector has to be maximised. Dynamic range: Since the purpose of the beamline is to detect differential signals smaller than 10 -6 with respect to the absorption edge jump, the dynamic range has to be maximised by carefully reducing the noise of the detector. 21
