Call: DRIFT_ELECTRON


coordinates

The starting point of the drift line should be specified in internal coordinates.

Internal coordinates coincide with the user coordinates when a Cartesian reference system is used. If polar coordinates are used, then the POLAR_TO_INTERNAL procedure should be used for the conversion.

The coordinates should be specified as constants, variables or expressions that are or evaluate to Numbers.


status

See status.

time

Contains, on successful completion, the total drift time.

The time is expressed in microsec.

This parameter should be a global variable, not a constant nor an expression. The global may exist prior to the call, but doesn't have to. If the global exists, the value it has before the call will be lost.


diffusion

Contains, on successful completion, the integrated diffusion.

The diffusion is integrated over the trajectory using a method described under diffusion.

The diffusion is expressed in microsec.

This parameter should be a global variable, not a constant nor an expression. The global may exist prior to the call, but doesn't have to. If the global exists, the value it has before the call will be lost.


multiplication

Contains, on successful completion, the exponentiated integral of the Townsend coefficient over the drift path.

The integration technique of the Townsend coefficient is described under multiplication.

The multiplication is a dimensionless number.

This parameter should be a global variable, not a constant nor an expression. The global may exist prior to the call, but doesn't have to. If the global exists, the value it has before the call will be lost.


attachment

Contains, on successful completion, the exponentiated integral of the attachment coefficient over the drift path.

The integration technique of the attachment coefficient is described under attachment.

The attachment is a dimensionless number.

This parameter should be a global variable, not a constant nor an expression. The global may exist prior to the call, but doesn't have to. If the global exists, the value it has before the call will be lost.
