Rydberg Core Laboratory

The Rydberg Core Laboratory (RCL) offers state-of-the-art facilities for interdisciplinary research, combining the natural sciences, associated applied sciences, and mathematical modelling. RCL is Halmstad University’s largest and most well-established laboratory and innovation arena, and consists of several smaller research lab units.

RCL is a stimulating research environment where innovative intra- and inter-disciplinary research projects are carried out. RCL is also a resource used by many of the courses at the university and provides an opportunity for undergraduates and masters students to experience practical research as part of their education.

RCL welcomes further collaborations with external institutions and businesses.

A lab with a history

The Rydberg Core Laboratory was opened in 2004. It is named after the famous Swedish physicist and mathematician Johannes “Janne” Rydberg, who was born in Halmstad in 1854. Read more about Janne Rydberg here.

Research units at the Rydberg Core Laboratory

The Rydberg Core Laboratory is made up of several smaller lab units. They all conduct a mixture of basic and applied research, often in collaboration with partners from industry and the wider society. Collaborative partners working in applied sciences enjoy access to state-of-the-art equipment and to competent research expertise, all as part of an innovative environment setting.

Environmental Biology Lab
In the research laboratories for biology and environmental science a wide range of biological and chemical analyses can be performed, including analysis of nutrient contents in soils, tissues and water, as well as gas composition and microscopy. The lab also includes an experimental wetland facility for testing the design and function of wetlands, and a biogas test lab for assessing substrates for biogas production.

Fab Lab
The Fab Lab is the digital fabrication and research facility of the Rydberg Core Laboratory. It houses 3D printers for additive manufacturing of prototypes and products in different polymers; 3D scanners for digitalisation of artefacts; laser and vinyl cutters for prototype manufacturing; textile embroidery machines for soft material design; electronics equipment for smart products design; and a foundry for wax modelling and casting of metal parts. The Fab Lab is part of a world-wide network of more than 1200 similar labs originating from MIT in Boston. In Fab Lab, students and researchers from academia and industry have regular opportunities to work together with a broader public and experience modern digital manufacturing.

Human Movement Lab
The Human Movement Lab is a research and teaching facility for the study of the physiology and biomechanics of exercise. The focus is on measurements of exercise capacity and movement mechanics, using advanced equipment to measure endurance, strength, power, flexibility, anthropometrics, muscle activation, vibration, kinematics and kinetics.

Mechanics Lab
In the Mechanics Lab students and researchers can study human and machine motion. It is equipped with a 3D-motion analysis system including six cameras and force plates able to measure up to 10 kN. Low-speed and high-speed accelerometers are also available to assess vibrations in applications that include the use of tools or vehicles. The Mechanics Lab also has equipment for tensile and compressive testing to measure material properties such as ultimate tensile strength, breaking strength, and elongation.

Microscopy Lab
The Microscopy Lab houses advanced computerised optical microscopes, a versatile scanning-probe microscope and a scanning electron microscope with element analysis capability for in-depth characterization of materials on different length scales down to atomic resolution.

Optoelectronics Lab
The Optoelectronics Lab houses state-of-the-art equipment for extremely sensitive electrical and optical device characterization. The optical characterization capabilities include a broadband Fourier transform spectrometer with integrated cryostat for measurements down to 5K (-268°C). The electrical characterization units offer nanovolt (10-9V) and femtoampere (10-15A) detection limits. For contacting of samples, the lab is equipped with a modern wedge bonder.

Surface Metrology Lab
The Surface Metrology Lab comprises 2D- and 3D-surface profilers (stylus, optical interferometry and atomic force microscopy) for surface texture and roughness analysis at lengthscales ranging from nanometers to centimeters. The lab is also equipped for measurements of surface properties, including chemical properties using the contact angle method; surface colour and gloss using spectrophotometry; and surface friction.

Tribology Lab
The Tribology Lab houses two tribometers for studying friction, wear and surface damage. A high-load tribometer (up to 20 kN) and a low-load tribometer (up to 1 kN) enable testing during reciprocating and rotary motions of the samples. Test parameters such as temperature, speed, displacement, load, and lubricants flow can be accurately controlled, and data such as friction forces, electrical resistance, and acoustic emissions can be recorded at high frequencies.
