IRRPROFIle


    Defines an irradiation profile for radioactive decay calculations

     See also DCYTIMES, DCYSCORE, RADDECAY, RESNUCLEi

     
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
Notes:
1) 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. 2) Several cards can be combined up to the desired number of irradiation intervals. 3) A negative value inserted in an odd WHATs (i.e. {\zz
WHAT(1)
}, {\zz
WHAT(3)
}, {\zz
WHAT(5)
}) will delete the previous irradiation interval. A series of negative odd WHATs will delete as many previously defined intervals.
Example 1:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 IRRPROFI 3600. 1.5E12 7200. 0.0 600. 4.2E12 IRRPROFI 1200. 0.0 3600. 1.0E10 * The defined irradiation profile consists of: * 3600s (1 hour) of irradiation at an intensity of 1.5E12 particles/s * 7200s (2 hours) of cooling (no beam) * 600s (1o minutes) of irradiation at an intensity of 4.2E12 particles/s * 1200s (20 minutes) of cooling (no beam) * 3600s (1 hour) of irradiation at an intensity of 1.0E10 particles/s
Example 2:
The same profile could have been achieved using separate IRRPROFI cards *...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 IRRPROFI 3600. 1.5E12 IRRPROFI 7200. 0.0 IRRPROFI 600. 4.2E12 IRRPROFI 1200. 0.0 IRRPROFI 3600. 1.0E10 * The defined irradiation profile consists of: * 3600s (1 hour) of irradiation at an intensity of 1.5E12 particles/s * 7200s (2 hours) of cooling (no beam) * 600s (1o minutes) of irradiation at an intensity of 4.2E12 particles/s * 1200s (20 minutes) of cooling (no beam) * 3600s (1 hour) of irradiation at an intensity of 1.0E10 particles/s
Example 3:
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 IRRPROFI 3600. 1.5E12 7200. 0.0 600. 4.2E12 IRRPROFI -1200. 0.0 -3600. 1.0E10 * The 4th and 5th irradiation intervals defined have negative duration, therefore * the two previous intervales will be deleted. The irradiation profile will * consist of a single interval 3600s long with an intensity of 1.5E12 particle/s
