Call: DRIFT_INFORMATION


q

Contains, on return, the charge of the last particle that has been drifted.

time

Contains, on return, the total drift time in microsec of the last drift line that has been computed.

electrode

The read-out group number of the electrode that was hit by the last drift line.

Read-out group numbers are assigned by the SELECT statement.


particle

Contains, on return, one of the following strings:

particle Meaning
electron An electron or a positron has been drifted
ion An ion with charge +1 or -1 has been drifted
vacuum An electron has been drifted in vacuum


path

Contains on return the length of the current drift line, estimated as the sum of the linear distances between the successive steps of the drift line.

The path is expressed in cm.


istat

This argument contains on return the numeric status code for the last drift line.

The numeric status code is explained in the introduction of the drift section, under the status header.


status

This argument contains on return a string with the status of the last drift line.

The status strings are explained in the introduction of the drift section, under the status header.


nsteps

Contains on return the number of steps in the last drift line that has been computed.

coord

Contains on return a coordinate of the starting or the end point of the current drift line.

The internal coordinate system is used - for Cartesian cells, this system coincides with the user coordinates, for polar cells, the INTERNAL_TO_POLAR procedure can be used to convert the coordinates.
