&DRIFT: SINGLE

f

The functions may use the following variables:

Symbol Meaning Note
X, Y, Z Position R, PHI for polar cells
EX, EY, EZ, E E-field at (x,y,z) ER, EPHI for polar cells
BX, BY, BZ, B B-field at (x,y,z) only if there is a B-field
VDX, VDY, VDZ, VD Local drift velocity VDR, VDPHI for polar cells
TIME Cumulative drift time -
PATH Cumulative path length -
DIFFUSION Local long. diffusion only if data is available
TOWNSEND Local Townsend coeff. only if data is available
ATTACHMENT Local attachment coeff. only if data is available
STATUS Drift line status code numeric status code

The numeric status code is a number which tells where the particle ended. These codes have a 1-1 correspondence with the status strings which are displayed in regular program output.

[No meaningful default functions are provided.]

PRINT

Requests a printed table of the coordinate and integrated drift time at each step and of the function f3.

[The table is by default not produced.]

PLOT

Requests a graph of function f1, plotted along the y-axxis, vs function f2, plotted along the x-axis.

[By default, a graph is not made.]

ELECTRON

The drift line will be calculated for an electron.

ION

The drift line will be calculated for an ion.

POSITIVE

The particle which is drifted has a positive charge.

NEGATIVE

The particle which is drifted has a negative charge.
