3. NATURE OF PHYSICAL PROBLEM SOLVED

O5S is designed to directly simulate the experimental techniques used to obtain the pulse height distribution for a parallel beam of mono-energetic neutrons incident on organic scintillator systems. Developed to accurately calibrate the nominally 2 in. by 2 in. liquid organic scintillator NE-213 (composition CH-1.2), the programme should be readily adaptable to many similar problems.

4. METHOD OF SOLUTION

O5S is a Monte Carlo programme patterned after the general-purpose Monte Carlo neutron transport programme system,  O5R. The O5S Monte Carlo experiment follows the course of each neutron through the scintillator and obtains the energy-deposits of  the ions produced by elastic scatterings and reactions. The light pulse produced by the neutron is obtained by summing up the contributions of the various ions with the use of appropriate light  vs. ion-energy tables.
Because of the specialized geometry and simpler cross section needs  O5S is able to by-pass many features included in O5R. For instance,  neutrons may be followed individually, their histories analyzed as they occur, and upon completion of the experiment, the results analyzed to obtain the pulse-height distribution during one pass on  the computer.
O5S does allow the absorption of neutrons, but does not allow splitting or Russian roulette (biased weighting schemes).
SMOOTHIE is designed to smooth O5S histogram data using Gaussian functions with parameters specified by the user.
