Ultrasonic sensor system for CaF2 interface monitoring with rods permanently embedded in crystal

The interface position of a CaF2 crystal was successfully monitored during growth using an innovative ultrasonic sensor system. The sensor system utilizes a top entry approach consisting of probe rods permanently positioned at the bottom of the crucible. Ultrasonic time of flight data (TOF) is used...

Zusammenfassung:The interface position of a CaF2 crystal was successfully monitored during growth using an innovative ultrasonic sensor system. The sensor system utilizes a top entry approach consisting of probe rods permanently positioned at the bottom of the crucible. Ultrasonic time of flight data (TOF) is used to determine interface position. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
