&OPTIMISE: ADD


length

The length of the periodicity, in cm for x and y, in degrees for phi. Periodicities in phi must divide 360 degrees, they are rounded if that is not the case.

Periodicities in r are not permitted.


coordinate

The position of the plane, in cm for x, y and r, in degrees for phi. The r coordinate of a circular plane must be > 0.

[This is a mandatory parameter; no default is provided.]


voltage

The potential of the wire or the plane in Volt

[Default: 0 V].


label

A single character by which you can identify the wire or the plane in SELECT statements.

The label 'S' has a special meaning in that these wires are by default selected.

[Planes are by default not given a label, a label is mandatory for wires.]


position

The location of the new wire.

This is a set of two numbers (x,y) or (r,phi) depending on whether the cell is entered in polar or Cartesian coordinates.

The units of x, y and r is cm, phi is in degrees.

[No default, these are mandatory parameters.]


diameter

The diameter of the new wire, expressed in cm.

[Default: 0.01 cm.]


tension

The weight used to stretch the new wire, expressed in grams.

Used by the FORCES command to estimate the wire displacement under gravitational and electrostatic forces.

[Default: 50 grams.]


length

The length of the new wire, expressed in cm.

Used by the FORCES command to estimate the wire displacement under gravitational and electrostatic forces.

[Default: 100 cm.]


density

The density of the material of which the new wire is made, expressed in g/cm3.

Used by the FORCES command to estimate the wire displacement under gravitational and electrostatic forces. Not relevant if the wires are vertical.

For copper-Beryllium wires, one can also enter CU-BE and for gold plated Tungsten one can type TUNGSTEN or W.

[Default: 19.3 g/cm3, i.e. 20 micron gold plated Tungsten wire.]
