Research topics

The Instrumentation Laboratory at the Université de Liège is part of the EMMI research Unit of the Department of Electrical Engineering and Computer Science - Engineering Faculty (FSA) - University of Liège (ULg).

This Laboratory is specialised in the characterisation of various materials geared towards engineering applications. Basically, the research carried out in the laboratory focuses on studying three kinds of materials:

  • Functional" ceramics with non-linear properties
  • Dielectrics et Insulators
  • Magnetic ordered nanostructures

 

Research - Equipment

Measurement of conducting materialsPhysical Property Measurement System PPMS (Quantum Design)

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 materials

Electrostatic voltmeter - Trek 341 (part of an anticorona varnish properties measurements setup)Insulating materials can be characterized using various devices including

  • a High-Voltage Electrostatic Voltmeter Trek 341 (DC and AC, ±  20 kV),
  • a Partial Discharge Measurement Set-up (ICM System),
  • High Voltage generators, lock-in amplifiers, electrometers …

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.
