channel(i1)/detectorstructure¶Detector description
Detector description
channel(i1)/detector/geometry_typeINT_0D¶Type of geometry used to describe the surface of the detector […]
Type of geometry used to describe the surface of the detector or aperture (1:’outline’, 2:’circular’, 3:’rectangle’). In case of ‘outline’, the surface is described by an outline of point in a local coordinate system defined by a centre and three unit vectors X1, X2, X3. Note that there is some flexibility here and the data provider should choose the most convenient coordinate system for the object, respecting the definitions of (X1,X2,X3) indicated below. In case of ‘circular’, the surface is a circle defined by its centre, radius, and normal vector oriented towards the plasma X3. In case of ‘rectangle’, the surface is a rectangle defined by its centre, widths in the X1 and X2 directions, and normal vector oriented towards the plasma X3.
channel(i1)/detector/centrestructure¶If geometry_type=2, coordinates of the centre of the circle. […]
If geometry_type=2, coordinates of the centre of the circle. If geometry_type=1 or 3, coordinates of the origin of the local coordinate system (X1,X2,X3) describing the plane detector/aperture. This origin is located within the detector/aperture area.

Components of the X1 direction unit vector in the (X,Y,Z) coordinate system, where X is the major radius axis for phi = 0, Y is the major radius axis for phi = pi/2, and Z is the height axis. The X1 vector is more horizontal than X2 (has a smaller abs(Z) component) and oriented in the positive phi direction (counter-clockwise when viewing from above).

Components of the X2 direction unit vector in the (X,Y,Z) coordinate system, where X is the major radius axis for phi = 0, Y is the major radius axis for phi = pi/2, and Z is the height axis. The X2 axis is orthonormal so that uX2 = uX3 x uX1.

Changed in version 4: Since this describes a closed countour first point must now be repeated at the end of the coordinate arrays of the children
