Abstract
The invention proposes that a casting mold be provided with a lining for the manufacture of a crystal body. The lining is removed from the casting mold together with the crystal body that has solidified in the lining and the lining serves as a protective cap for the crystal body. Additional functional layers for the protective cap or the scintillator plate can be integrated into the lining.
Claims23
A method of manufacturing a crystal body from a melt, comprising the steps of:
- providing a casting mold, the casting mold having an inside surface;
- lining the inside surface of the casting mold with a lining;
- introducing a melt into the casting mold and on top of the lining;
- solidifying the melt to form a crystal body so that the crystal body is attached to the lining;
- and
- removing the crystal body and lining from the casting mold whereby the lining serves as a protective cap for the crystal body.
