This is a similar problem as Jyoti’s . Zero result after biasing
Please find attached the input file. My results are for VOID=AIR as well as VOID=VACUUM. ( 1 cycle Run to check the input).
My geometry is cylindrically symmetrical. Bias layer thickness = 1.2 cm Lead. 25 Co-60 sources, hence source.f is used.3010b.inp (10.0 KB) source.f (12.7 KB) VoidAir,55.7to75.7.lis (812 Bytes) VoidVacuum,55.7to75.7.lis (812 Bytes)
- Void = Air: The Dose rate starts falling from R=55.7 to R=59.7 (as expected), through shield; it falls to zero then…later again the values are scored but larger than that at inner shields. Is anything wrong with the Biasing given?
- Void = Vacuum: it falls initially, logical, zero in between, again a value…but no score outside the shield (R=73.7 to R=75.7) - implies something is not okay with the Biasing applied…
Can you please help me with some errors which you can find with my approach and help me find the solution ?
Thanks and regards,
