&DRIFT: ARRIVAL-TIME-DISTRIBUTION: SCAN

RANGE

The extent of the tracks along the scanning axis.

The range is specified in the usual coordinate system, not relative to the electrodes.

If the scanning range does not cover the full acceptance of an electrode, some of the electrons to reach the electrode in the real chamber, will be absent in the simulation.

If the range is chosen too large, the accuracy suffers unless the LINES parameter is set to a high value. Moreover, considerable waste of CPU time occurs.

[Default: the entire scanning range as given by AREA.]

ANGLE

The angle of the tracks with respect to the scanning-axis.

[Default: initially 0\°. The angle that you set is kept as default for the next call.]
