Call: AVALANCHE


option

A string that can contain one or more of the following options:

Option Meaning Default
ATTACHMENT Include attachment If present
MONTE-CARLO Monte Carlo drifting Yes
NOATTACHMENT Don't include attachment If not present
NOPLOT-ELECTRON Don't plot electron drift lines Yes
NOPLOT-ION Don't plot ion drift lines Yes
NOTOWNSEND Don't include multiplication If not present
PLOT-ELECTRON Plot electron drift lines No
PLOT-ION Plot ion drift lines No
RUNGE-KUTTA Runge Kutta Fehlberg integration No
TOWNSEND Include multiplication If present

The TOWNSEND and ATTACHMENT options can only be selected if the corresponding data has been entered in the gas section.

A plot frame (e.g. with PLOT_DRIFT_AREA) has to be opened before the call to AVALANCHE if you wish to use the PLOT-ELECTRON or PLOT-ION options.


n_electron

The number of electrons produced in the avalanche minus the number of electrons lost via attachment.

This is an optional output parameter and should therefore be modifiable. The value assigned to this parameter on entry is not used.


n_ion

The number of ions produced in the avalanche.

This is an optional output parameter and should therefore be modifiable. The value assigned to this parameter on entry is not used.


formula

A formula that states the quantity that should be entered in the histogram. Each formula can make use of the quantities from one (and only one !) of the following sets:

If you wish to have an histogram filled only under certain conditions, then use format: `value,condition` where "value" is the quantity to be entered in the histogram and "condition" the condition under which the quantity should be entered. "value" Should evaluate to a Number while "condition" should be a Logical.

This argument should be provided in the form of a String. The string is not modified in the call.


histogram

A reference to the Histograms that are to receive the statistics on the avalanche process.

If this argument is of a type other than Histogram, then any storage associated with it is liberated and a new histogram is created with 100 bins and an automatically adjusted range.

You may also give an existing histogram as argument, in which case new entries will be added to it.

This is an optional parameter. Since it is used for output, it should be modifiable.
