The scintillation CsI was also calibrated with protons of 15, 20, 23MeV. The average energy calibration is 1. 047MeV per channel. Energy calibration for heavy ions was completed with multiplication factor 1/12. 75. The energy calibration is around 1. 1MeV per channel for oxygen ion and iron ions when energy deposition is less than 50MeV in each detector.

Finally, on Earth-space paths, by applying a modification of the Rytov method that incorporates spatial frequency filter function under strong fluctuation conditions, a tractable model is developed for the scintillation index of a Gaussian optical beam wave that is valid under moderate-to-strong irradiance fluctuations. The scintillation indexes for collimation Gaussian beam are predicted by this analytic model, based on ITU-R C〓 model.
