Concept 80 System Constituents: • Two impedance analyzers with sample cells: a) Alpha-A (3 µHz to 20 MHz) with Alpha Active Sample Cell ZGS b) E4991A RF Materials Analyzer (1 MHz to 3 GHz) with RF Dielectric sample cell BDS 2200 (14 mm version) or BDS 2100 (7 mm version) • RF mounting stage • Quatro Cryosystem: -160 °C to 400 °C • Full software package WinDETA+WinPLOT+WinTEMP+WinFIT • Data Acquisition Unit (computer with GPIB interface, 22” LCD monitor, printer)

12. Alpha-A Active Sample cell ZGS (3 µHz .. 20 MHz; 40 MHz with Alpha-AT) Sample cell with integrated test interface (current-to-voltage converter/amplifier) and optimized frequency performance. High-performance dielectric, conductivity or impedance measurements from 3 µHz up to 40 MHz (with Alpha-AT only). Rigid air-line connection from electronics to electrodes suppresses performance-limiting cable effects at high and low frequencies due to cable inductance and piezo-induced charges caused by mechanical noise.

14. RF extension line (1 MHz to 3 GHz) High-temperature stable, low-loss precision line with two APC-7 connectors and Pt100 temperature sensor. Mounted between the impedance input of the RF Analyzer and the RF sample cell for thermal isolation. The combination of sample cell and extension line can be operated in the temperature range from -160°C to 400°C.

15. Quatro Cryosystem: High Precision Turnkey Temperature Control 4 Range: -160°C to 400°C Ramps: 0.01°C/min to 20 °C/min Stability: 0.01°C Overshooting after set point step: typically < 0.2°C Stabilization times typically < 8 minutes (for 0.1°Cstability) low nitrogen consumption due to automatic pressure-temperature adaptation automatic adaptation of controller parameters vacuum-isolated cryostat and nitrogen lines

16. Quatro Cryosystem A heating element builds up a specified pressure in the liquid nitrogen dewar in order to create a highly constant nitrogen gas flow. Pressure and temperature in the dewar are measured by two channels of the Quatro controller. Heated by a gas jet, the nitrogen gas flows directly through the sample cell which is mounted into the cryostat. The gas and sample temperatures are measured by the two remaining channels of the QUATRO controller. The four channel arrangement allows stable, fast and safe system operation in combination with low liquid nitrogen consumption (economical mode). The cryostat is vacuum isolated by a two- stage rotary vane vacuum pump, providing thermal isolation by low vacuum (< 10 µbar). 4
