Call: ADD_SIGNALS

shift

Consider the usual signal induction process. An ionisation electron is deposited somewhere, it drifts towards an anode where it multiplies. Currents are induced both by the incoming electron and by the outgoing ions.

The electron signal naturally starts at the time it starts to drift. The signal will initially be small, but it will become larger as the avalanche grows. This part is easy to simulate: you drift an electron using one of the procedures designed for this and use ADD_SIGNALS to compute the currents that are induced in the electrodes.

There is a subtlety when it comes to the ions: the signals induced by the ions should not start at the time they start to drift, but at the time the electron started to drift. To account for this delay, you specify the electron drift time as first argument of the ADD_SIGNALS procedure.

[By default, this delay is set to 0.]

weight

This optional argument takes care of the case where more than one particle follows the same drift path. The signals are multiplied by the weight and only then added.

[By default, the signals are given a weight of 1.]

options

A String which can contain one or more of the following options:

Option	Meaning	Default
`CROSS-INDUCED`	Requests cross induced signals	Is default
`DIRECT`	Only direct signals are computed	Not default

The options have the same effect as the CROSS-INDUCED option of the SIGNAL command.
