内容記述 | Diffusion characteristics of auroral X-rays in the atmosphere have been investigated by means of a Monte Carlo simulation to estimate how much degree of out-of-focus is introduced into auroral X-ray images at balloon altitudes. The simulation calculations were carried out for the four different spectral functions of photon sources: a) mono-energy parallel beam, b) mono-energy, isotropic, c) exponential and d) power-law energy spectra, isotropic. The calculation results are summarized as follows. 1) In case of the omni-directinal detector, an isotropically incident beam enlarges into the width of 10-13 km at l0g/c㎡ depth, regardless of the spectral function. 2) The detectors with a half collimator angle of 30and l0reduce it into 8-9 km and 3-4 km, respectively. 3) It appears a kind of ghost image with increasing inclined angle of the collimated detector, amounting to the same order of brightness with the genuine image. The out-of-foci of some circular source images are illustrated as a function of atmospheric depth, spectral function and collimation and inclined angles of the detector. | |||||||||
