4.14. Setting custom samples for POWCAL edgeprofparameters¶
To set a custom power profile in POWCAL edgeprofparameters
the user
must fill the following parameters:
profile_formula
: ‘samples’power_loss
: -1power_split
: 1coord_of_positions
: ‘radius’number_of_positions
: 100positions
: 100 positions of user specified left and right rangedeposition_profile
: 100 power values on the positions
To properly prepare the profile the user must take into account that:
- SMARDDA already provides radial distance with a negative sign!
- The deposition profile must be divided by a normalization factor!
So in order to prepare a range, you would normally set it from -100 mm to 300 mm radial distance from the boundary. In order to provide the same to SMARDDA, the range is actually -300 mm to 100 mm. The range is reversed!
The normalization factor, with which you must divide your profile is
These values are read from the geoq_geoq.out
output file of target GEOQ.
The values are stored by first line defining the name of the parameter and
the second line containing the value of the parameter:
- \(R_m\) : rbdry
- \(B_m\) : bpbdry
- \(B_{totbdry}\) : btotbdry
A dialog under Smiter –> Case –> Custom single exponential profile prepares a custom single exponential profile where the user specifies the \(Q_0\), \(\lambda\) and the ranges. Then by selecting a SMITER case, the normalization factor is calculated to prepare a normalized power deposition profile.
