TIME-CUT
Sets transport time cutoffs for different particles
See also TCQUENCH
WHAT(1)
= transport time cutoff (nsec)
Default
: no cut off
WHAT(2)
: not used
WHAT(3)
: not used
WHAT(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 particle WHAT(4)
...").
Default
= 1.0
WHAT(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 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).
3) If the source has been defined as a radioactive isotope (command
BEAM with SDUM
= ISOTOPE), transport of each isotope decay secondary
starts with an age equal to the time of decay.
Example:
TIME-CUT 3000.0 0.0 0.0 8.0 0.0 0.0
