چکیده انگلیسی
We have carried out Monte Carlo simulations that support the linear analytical theory of time-focusing on crystal analyzer instruments and provide further interesting details on the time-of-flight signals obtained for different geometries. Important non-linear effects are revealed close to the time-focusing conditions. Calculations for realistic sizes of spectrometer elements indicate an elastic-scattering time-of-flight spread Ït/t approximately 7.9Ã10â5, far less than the conventional (and incorrect) ÎÎcotÎ estimate for such type of instrument. The aim is to provide a basis for design of spectrometers of the highest possible resolution with the highest possible counting rates, meanwhile to reveal new flexibilities for the design e.g. tunable analyzer energy.
