TIME-CUT

Sets transport time cutoffs for different particles

See also TCQUENCH

     WHAT(1) = transport time cutoff (nsec)
               Default: no cut off

     WHAT(2) = transport time cutoff delay (nsec)
               Default = 0.0

     WHAT(3) = material number for the "start" signal from which time
               is measured (useful for calorimetry)
               (Not implemented at present)
               Default: "start" at creation time

     WHAT(4) = lower bound of the particle numbers for which the
               transport time cutoff and/or the start signal is to be
               applied
               ("From particle WHAT(4)...").
               Default = 1.0

     WHAT(5) = upper bound of the particle numbers for which the
               transport time cutoff and/or the start signal is to be
               applied
               ("...to particle WHAT(5)...").
               Default = WHAT(4) if WHAT(4) > 0, all particles otherwise.

     WHAT(6) = step length in assigning numbers. ("...in steps of
               WHAT(6)").
               Default = 1.0

     SDUM :    not used

     Default (option TIME-CUT not given): no time cutoff for particle
             transport

Notes:

  • 1) The transport time cutoff should not be confused with the time cutoff for scoring (see TCQUENCH).

  • 2) Particles outside the time gate defined by TIME-CUT are discarded (a summary is printed at the end of the standard output).

Example:

 *...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
 TIME-CUT      3000.0       0.0       0.0       8.0       0.0       0.0
 *  Stop transporting neutrons after 3000 nsec
