Measurement of conducting material

Electrical, magnetic and thermal properties of conducting materials (metals, semi- and super- conductors, electro-ceramics) can be measured using a Physical Property Measurement System (PPMS - Quantum Design). The system is based on a liquid helium cryostat (300 K to 2 K) combined with a superconducting magnet (0 to  9 T) and allows samples of small size (typically < 1 cm) to be measured. Various home-made data acquisition set-ups have been developed for more specific tests. They include closed-cycle helium cryostats (300 K to 20 K) and various PC-controlled devices (nanovoltmeters, lock-in amplifiers, temperature controllers,…).

Measurement of insulating material

Insulating materials can be characterized using various devices including

Several ovens are used for thermal ageing as well as high-temperature measurements (20°C to 200°C).

Measurement of Radon activity

Various measurement systems, including a PRO type Genitron Alphaguard monitor, are available. They allow dynamic measurements of the volumic activity of radon in air, water and soil to be carried out. In addition, a large experimental cell (7m³) has been realised and instrumented in order to perform a simultaneous intercomparison of several radon monitors.
