3. DESCRIPTION OF PROBLEM OR FUNCTION
TIMOC-ESP is an "Event Scanning Program" to analyse the events (collision or boundary crossing parameters) of Monte Carlo particle transport problems. It is a modular program and belongs to the TIMOC code system. Whilst TIMOC-72 deals with stationary problems, the time-dependence is dealt with in ESP. TIMOC-ESP is primarily designed to calculate the time-dependent response functions such as energy-dependent fluxes and currents at interfaces.

4. METHOD OF SOLUTION
The output of TIMOC-72 is transferred to TIMOC-ESP using a data set which acts as an interface between the two programs. Time dependent transport events are sampled at each crossing of any specified boundary in TIMOC. TIMOC-72 provides the parameters for ESP which are:
- time of the event
- neutron weight
- cosine of the angle between the flight direction and the normal to the surface
- the indices of both regions
- the history number
Fundamentally, three time options are permitted by ESP, which give the current, the angular flux and the time-integrated flux functions between two specified regions.
An eventual extension to other quantitites is simple and straight- forward - ESP will accept input data for other options such as the calculation of the point flux, the collision density and the flux derived from this estimator, but the coding required for these calculations has yet to be implemented (1977).
