Along the brook on Road C, a thin film of ice formed in the grass, visible in the upper third of the picture.
This is one of the several conning towers that served as the feed-through for a corrector magnet in the Tevatron. The red silicone protected the electrical connections from corrosion, which could lead to electrical shorts. An ice ball was usually present around the whole tower when the magnet was in use.
Dipole magnets produce the dominant magnetic field that bends the particles traveling through the Main Ring. This particular dipole magnet sits skewed and bends both vertically and horizontally — deliberately so! — just ahead of the DZero collision hall.
