Title Precision measurement of x-ray line spectra by x-ray line dispersion in a gas microstrip detector
Abstract It is shown that when a gas microstrip detector (GMSD) is operated in such a way as to gain freedom from detector wall effects, the response of the detector to an x-ray line is stable and can be fitted reliably with a lognormal distribution function. The lognormal function permits the fitting of adjacent, overlapping x-ray lines with an accuracy in position of a few eV with an attendant penalty in the statistics required for a given precision in the amplitude measurement. Experimental data and montecarlo simulation data are presented to indicate the possible range of usefulness of this technique for energy-dependent x-ray line spectroscopy in applications (such as x-ray fluorescence analysis). The usefulness of the lognormal fits for detector studies is also noted.
