Symbol | meaning |
---|---|
TIME
| total drift time [micro seconds] |
LENGTH
| length of the drift line [cm] |
DIFFUSION
| integrated diffusion coefficient [cm] |
AVALANCHE
| integrated and exponentiated Townsend coefficient |
LOSS
| integrated and exponentiated attachment coefficient |
[The default function to be minimised is TIME.]
The following variables can be used:
Symbol | Meaning |
---|---|
TIME

LENGTH
| length of the drift line [cm] |
DIFFUSION
| integrated diffusion coefficient [cm] |
AVALANCHE
| integrated and exponentiated Townsend coefficient |
LOSS
| integrated and exponentiated attachment coefficient |
STATUS
| information on what happens to the particle |
All variables are of type Number except for STATUS which is a String and which can have one of the following values:
`Left_Area`, `Too_Many_Steps`, `Abandoned`, `Hit_Plane`, `Left_Drift_Medium`, `Left_Mesh`, `Hit_X_Wire` and `Hit_X_Replica`. `X` is the label that you have assigned to the wire.
[The default selection curve returns always True.]
The range of T can be specified via RANGE.
[No default curve is provided.]
[No default RANGE is provided.]
[The default value for N is 20.]
[This is the default.]
[By default, minimisation is done for electrons.]
[The default is NEGATIVE.]
[This is the default.]
[The default value is 10E-4, which is also the smallest reasonable value on computers like Vax and IBM. On Cray and other computers with 64 bit precision, eps_f can be made smaller.]
[The default value is 10E-4, which is also the smallest reasonable value on computers like Vax and IBM. On Cray and other computers with 64 bit precision, eps_pos can be made smaller.]
[By default 20.]
[This is default.]
[No such output is produced by default.]
