Drawings associated with magnetic verification
- A drawing of the conceptual design of the G0 SMS magnet mapping apparatus - August 19, 1999 Obsolete
- An updated version, of the G0 SMS magnet mapping apparatus (essentially just before ordering parts) - October 6, 1999 Obsolete
- The probe holder for the G0 SMS magnet mapping apparatus. - March 28, 2000

- The G0 SMS magnet mapping apparatus. This contains the probe boom and probe-holder attached. But please note that the boom and probe-holder are not fully completed in this drawing (the most recent versions of those components have not been imported into this particular drawing yet -- but as far as the gantry footprint is concerned, those details don't matter). - May 11, 2000
- Drawings of the photo-diode block for the probe holder. This drawing is only provided in Autocad 2000 format due to the use of multiple views of the 3-d model (which do not translate well to Autocad R12). - May 26, 2000

  - Pictures (3-d rendered images) of the final design of fixtures for magnetic verification alignment - Bartoszek Engineering, June 23, 2000
  - A 3-D model of the magnetic verification alignment hardware. There are actually several model files because the cryostat, probe, and carriage have been "XREFed" into the main assembly called magver_assy2.dwg. To view the model: load all four drawing files into the same directory (doesn't matter what you call it) and open the main assembly (magver_assy2.dwg). - L Bartoszek and R. Luther, June 22, 2000
