摘要： A pulling head for a crystal growth furnace. The pulling head includes a servomotor and a rotatable housing attached to the servomotor, wherein the housing includes first, second, third and fourth housing magnets. The pulling head also includes a shaft attached to a scale and a connection device having first and second connection magnets. The first connection magnet is arranged between the first and second housing magnets to generate first and second magnetic repulsion forces and the second connection magnet is arranged between the third and fourth housing magnets to generate third and fourth magnetic repulsion forces. A rotation coupling is attached between the shaft and the connection device wherein the scale weighs the shaft, rotation coupling and the connection device. The servomotor rotates the housing and rotation of the housing is transmitted by the magnetic repulsion forces to the connection device to rotate the connection device.

摘要： Roll forming is used for re-shaping an iridium crucible. The crucible is placed on a platen. The platen rotates the crucible while heat is applied by a plurality of torches. A plurality of rollers press on the rotating, heated crucible to re-shape. The roll forming allows for a greater number of repetitions of the re-shaping, increasing the number of uses per expensive re-fabrication of the crucible. The roll forming may provide more exact re-shaping

摘要： The use of the effect of crystallographic axis orientation on the effectiveness in annealing in multiple atmospheres and chemical compositions of lutetium oxyorthosilicate crystals and other scintillator crystals is disclosed. By controlling axis orientation an favorable annealing condition can be selected to repair both internal interstitial and vacancy defects through the crystal lattice. Axis orientation can be further utilized to control the uniformity of surface finish of chemically etched crystal.

摘要： A cantilever device for extending capacity of a scale used in a crystal growth apparatus having a pulling head wherein upward movement of a support column in the pulling head decreases a weight measured by the scale. The device includes a horizontal arm having first and second brackets, wherein the first bracket is attached to the pulling head. The device also includes a plate that extends through openings in the first and second brackets, wherein the plate includes a contact end and a free end. Further, the device includes a flexible element attached between the arm and the plate to form a pivot to enable rotation of the plate. A load is positioned on the plate wherein the load causes rotation of the plate about the pivot to cause upward movement of the contact end to move the support column upward to decrease weight measured by the scale.
