defines an irradiation profile for radioactive decay calculations
(see also DCYTIMES, DCYSCORE, RADDECAY)
WHAT(1) = length of a newly defined irradiation interval (in s)
> 0.0 : a new interval is added with length WHAT(1)
= 0.0 : ignored
< 0.0 : the last defined interval (if any) is deleted
Default = no new irradiation interval is defined
WHAT(2) = beam intensity of the newly defined (see WHAT(1)) irradiation
interval
>= 0.0 : beam intensity in particles/s (0 is accepted)
< 0.0 : considered as 0.0
Default: 0.0 particles/s
WHAT(3) = the same as WHAT(1)WHAT(4) = the same as WHAT(2)WHAT(5) = the same as WHAT(1)WHAT(6) = the same as WHAT(2)SDUM = not used
Default (option IRRPROFIle not given): no irradiation interval is defined
Note: Several cards can be combined up to a maximum of 20 irradiation
intervals. Decay times as requested by DCYTIMES commands will be
calculated from the end of the last one. Scoring during irradiation
can be obtained giving negative decay times in DCYTIMES
Example:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
IRRPROFILE 1800. 1.5E12 250. 3.E10 4500. 4.2E12
* The profile defined consists of 1800 s of irradiation at an intensity of
* 1.5E12 particles/s, followed by 250 s at low intensity (3.E10 particles/s),
* and then a third 4500 s interval at 4.2E12 particles/s
