SPOTTIME

The SPOTTIME card is used in conjunction with SPOTBEAM, SPOTDIR, SPOTPOS and SPOTTRAN to define the time interval/offset of multiple beam spots. A new primary is created randomly in any of the listed beam spots according to their respective weight or in sequential order. See SPECSOUR SPECSOUR.

Warning : These five cards are activated by indicating SDUM = BEAMSPOT in the SPECSOUR card. Barring this, the spot cards will be discarded.

WHAT(1) =

spot beam time offset starting time (s). A negative number resets to default Zero is ignored

Default

=  0.0

WHAT(2) =

spot beam time offset end time (s). A negative number resets to default Zero is ignored

Default

=  0.0

WHAT(3)

not used

WHAT(4) =
lower bound of the spot number to which the start time WHAT(1) and stop time WHAT(2) apply. The spot numbers or names are those assigned using a SPOTBEAM card.
(“From spot ``WHAT(4)``…”)
Default

= 0

WHAT(5) =
upper bound of the spot number to which the start time WHAT(1) and stop time WHAT(2) apply. The spot numbers or names are those assigned using a SPOTBEAM card.
(“…to spot ``WHAT(5)``…”)
Default

= WHAT(4)

WHAT(6) =
step length in assigning the spot number.
(“…in steps of ``WHAT(6)`` ”)
SDUM

not used

Notes

  1. When a beam particle of a given spot is generated, the starting time offset of the particle is chosen randomly between What(1) and What(2)
