+ | One module is always located centrally so that the number of modules in a rod is always an odd number. For example, numModules 3 will result in 7 modules per rod. | ||

+ | Here are some resolutions after making the following changes: | ||
+ | * extend layer 1 and 2 by one module | ||
+ | * bring layer 2 closer to beam pipe (58 mm) | ||
+ | * move layer 3 and 4 out (120 mm, 180 mm) | ||
+ | * replace disc 1 (of 2 rings) with 3 discs of 1 ring each (at 265 mm, 285 mm, and 335 mm) | ||
