0158 #### Radiator
0159 - radiator is defined in a wedge of azimuthal space, composed of aerogel and a
0160 filter; the filter is applied to the back of the aerogel, so that it separates
0161 the aerogel and gas radiators; an airgap is defined between the aerogel and filter
0162 - dimensions:
0163 - `frontplane`: front of the aerogel, w.r.t. front plane of the vessel envelope
0164 - `rmin` and `rmax`: inner and outer radius (at the front plane; radial bounds are conical)
0165 - `thickness`: radiator thickness, defined separately for aerogel and filter
0166 - `pitch`: controls the angle of the radiator (0=vertical)

0173 ##### Sensor module
0174 - dimensions:
0175 - `side`: side length of the square module
0176 - `thickness`: thickness of the sensor module
0177 - `gap`: provides room between the squares, to help prevent them from overlapping
0178 - note: the values of `side` and `gap` will determine how many sensors there are, since the
0179 sensor placement algorithm will try to place as many as it can in the specified region

0206 Material should be equivallent with 3x0.5cm Al, spread over the entire available distance (`PFRICH_services_length`).
