Thanks to Riccardo Giannitrapani of the Údine group we have a new tool for checking the geometry and diagnosing problems. It is a viewer somewhat analogous to SolidView Lite, but it runs off our xml geometry description. Of primary interest here are the features which allow you to
See this directory for a sampling of screen shots.
The image below shows all ribbons as described by the xml geometry. Segments of fixed X are red. Each acutal X-ribbon is artificially divided into 3 pieces: one for the top and one for each of two sides. Segments of fixed Y are magenta. Each actual Y-ribbon is simulated as 7 segments.
You can see how the ribbons are located with respect to ACD tiles and support structures in the following picture (X-Z projection).
This picture shows the bottom side tiles and a single crystal from the top layer. Since the crystal has been selected, its dimensions and location (of center of mass, relative to LAT origin) are also displayed to the left. In particular, we can see that it extends in Z from approximately -68.02 mm to -48.12.
Select a bottom tile to find the location of its bottom edge: about Z = -48.3.
