Sets transport time cutoffs for different particles See also TCQUENCHWHAT(1)= transport time cutoff (nsec)Default: no cut off * Start_Devel_seqWHAT(2)= transport time cutoff delay (nsec)Default= 0.0 * End_Devel_seq * Start_Prod_seq *WHAT(2): not used * End_Prod_seq * Start_Devel_seqWHAT(3)= material number for the "start" signal from which time is measured (useful for calorimetry) (Not implemented at present)Default: "start" at creation time * End_Devel_seq * Start_Prod_seq *WHAT(3): not used * End_Prod_seqWHAT(4)= lower bound of the particle numbers (or corresponding name) for which the transport time cutoff and/or the start signal is to be applied ("From particleWHAT(4)...").Default= 1.0WHAT(5)= upper bound of the particle numbers (or corresponding name) for which the transport time cutoff and/or the start signal is to be applied ("...to particleWHAT(5)...").Default=WHAT(4)ifWHAT(4)> 0, all particles otherwise.WHAT(6)= step length in assigning numbers. ("...in steps ofWHAT(6)").Default= 1.0SDUM: not usedDefault(option TIME-CUT not given): no time cutoff for particle transportNotes: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). 3) If the source has been defined as a radioactive isotope (command BEAM withSDUM= ISOTOPE), transport of each isotope decay secondary starts with an age equal to the time of decay.Example:*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+...TIME-CUT 3000.0 0.0 0.0 8.0 0.0 0.0* Stop transporting neutrons after 3000 nsec
