Electrodynamics Laboratory
About Us
Electrodynamics Laboratory consists of two sub-laboratories, Kibble Balance and Plasma.
Fields of Activity
The Electrodynamics Laboratory is developing the national kilogram standard in the Kibble Balance sub-laboratory. In addition, the development of Kibble balancing devices with a measurement capacity of up to 10 grams with high commercial potential is being carried out.
Electrodynamics Laboratory, Plasma sub-laboratory develops plasma diagnostic techniques, innovative plasma technologies and machine learning based plasma spectroscopy (LIBS, laser induced breackdown spectroscopy).
Kibbe Balance Laboratory
The Kibble Balance Laboratory was established to establish the "National Kilogram Prototype", to integrate it into the international metrology system through international comparisons and to ensure mass measurement unity by providing primary level mass calibration services.
As of May 20, 2019, a new definition of the kilogram, one of the basic units of the International System of Units (SI), is expected to be in effect. With the redefinition of the unit, the current dependence on the physical object in the definition and realization of the kilogram will be removed and the kilogram will be associated with Planck's constant (h), the fundamental constant of quantum physics. With this new definition, which guarantees the long-term stability of the mass scale, the kilogram will be realized independently of time, location and person.
Today, there are two independent primary methods, officially accepted by the Consultative Committee on Mass and Related Measures (CCM), that have been developed to achieve the new definition of the kilogram unit with the highest accuracy and lowest uncertainties:
- Kibble (Watt) Balance Experiment
- X-Ray Crystal Density (XRCD) Experiment
Kibble balancing experimental setups based on the principle of balancing mechanical and electrical power can be designed with different geometries and experimental protocols. Kibble Balancing Laboratory contributes to the studies carried out worldwide with the Oscillating Magnet Kibble Balancing Experimental setup established within the scope of the Kibble Balancing project launched in the second half of 2014. With the oscillating magnet experimental setup, a completely new measurement concept was created by following an alternative path to the leading institutes in the field of scientific metrology and the Turkish brand of Kibble balancing experiments was developed.
At the end of the successfully completed first phase of the project 3 x 10-7 measurements were made with relative uncertainty. Although the studies were started recently, the uncertainty levels of institutes that have been working in this field for relatively longer years were reached in a short time.
In the second phase, where the "National Kilogram Prototype" will be created, 2 x 10-8 relative uncertainty level is aimed to be reached. If this target is achieved, the country will no longer be dependent on external sources for mass traceability, and TÜBİTAK UME will be in a position to provide international mass calibration services to institutes that do not have a primary method and even provide technology transfer to developing institutes.
Plasma Metrology Laboratory
The aim of the laboratory, which is in the establishment phase, is to first establish the infrastructure of plasma metrology, a new field in metrology, and then contribute to the development of plasma-related technologies. Plasma, defined as the fourth state of matter, consists of almost equal numbers of negatively charged electrons and positively charged ions. Due to its highly complex structure, plasma contains many physical processes that need to be diagnosed. The development of controlled plasma can add new dimensions to metrology and future breakthroughs. Plasma technologies are the backdrop for today's cutting-edge industry. Plasma will play a key role in the invention of modern technologies and new devices. The production of flexible nano-electronic, micro-electronic and electromechanical devices, innovative chemical applications for bio-fuel synthesis, realization of micro-batteries, surgical applications and direct plasma utilization for pharmaceuticals are some of the next generation plasma applications. Furthermore, the extraordinary properties of plasma could pave the way for the development of new measurement methods and measuring instruments in different fields of metrology. In addition, in the future, fusion is planned to be used as a green, safe, sustainable energy source, a major breakthrough to combat climate change. A better understanding of the complex nature of plasma and the characterization of its chemical, physical and electrical properties could lead to significant advances towards controlled fusion reactions.
