In accordance with the NASA Space Act of 1958 the MSFC has provided for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof,

Since July 1, 1960, when the George C, Marshall Space Flight Center was organized, the reporting of scientific and engineering information has been considered a prime responsibility of the Center. Our credo has been that "research and development work is valuable, but only if its results can be communicated and made understandable to others."

The N number shown for the reports fisted is assigned by the NASA Scientific and Technical Infor- mation Facility, Baltimore, Maryland, indicating that the material is unclassified and unlimited and is available for public use. These publications can be purchased from the National Technical Information Serve ;e, 5285 Port Royal Road, Springfield, Virginia 22161, The N number should be cited when ordering,

The Space Telescope (ST) will be subjected to charged particle strikes in its space environ- ment. ST's onboard Fine Guidance Sensors utilize multiplier phototubes (PMT) for attitude deter- mination. These tubes, when subjected to charged particle strikes, generate "spurious" photons in the form of Cerenkov radiation and fluorescence which give rise to unwanted disturbances in the pointing of the telescope.

This paper presents a stochastic model for the number of these spurious photons which strike the photocathode of the multiplier photo- tube which in turn produce the unwanted photon noise. The model is applicable to both galactic cosmic rays and charged particles trapped in the Earth's radiation belts.

The model which has been programmed allows for easy adaptation to a wide range of particles and different parameters for the photo- tube of the multiplier.

The probability density functions for photon noise caused by protons, alpha particles, and carbon nuclei were generated using thousands of simulated strikes. These distributions will be used as part of an overall ST dynamics simulation.

The sensitivity of the density function to changes in the window parameters has also been investigated.
