Abstract
A crystal growth guidance mechanism for use in crystal growing apparatus. The guidance mechanism, which is disposed between a crystal puller and a crystal forming die comprises a plurality of gravity damped guide rods mounted on ramped supports. The rods have sufficient mass and number so that when acting in unison the rods will provide sufficient resistance to prevent puller induced motion in the crystal from being translated down into the die top, while individual guide rods 'float' on the surface of the growing crystal whereby each rod will move out of the way of any localized surface perturbations in the growing crystal.
