esz to celebrate 40th anniversary
On June 21, 1976 Siegfried Fleischmann laid the ground for what would turn into Europe’s leading metrology laboratory. Typically, with respect to the latter, the story told is some mysterious “garage”, a keen “idea” and a legendary “entrepreneur”. In this case the “garage” would turn into the basement of Siegfried Fleischmann’s family home, the “idea” a simple portion of common sense and the legendary entrepreneur a straight forward thinking engineer. esz AG is to commemorate this event by a series of activities throughout the Summer of 2016. Happy Anniversary!
World Accreditation Day
The 9th of June is World Accreditation Day. World Accreditaion Day is a global initiative, established by the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC) to raise awareness of the importance of accreditation and quality management. This year’s focus is on the “public sector”. Germany’s national accreditation body is Deutsche Akkreditierungsstelle GmbH or DAkkS for short. DAkkS continuously and periodically assess a esz AG’s competency, expertise and compliance with ISO/IEC 17025. esz AG carry out stationary and onsite accredited calibration.
A Cool Thing
The joint research team among PTB (Germany’s national institute for measurements and technology), supracon AG and esz AG calibration & metrology report another groundbreaking success: An AC Quantum Voltmeter was installed on a pulse tube cooler (PTC), driven with a 4 kW air-cooled compressor. The idea is to untie Josephson-Systems from obstacles such as limited availability, access and safety precautions derived from the common liquid helium based cooling operation. Introducing a dry-cooled system proves to be advantageous in particular for industrial calibration laboratories such as esz. The team carried out a detailed testing under standard laboratory conditions at esz’s stationary calibration laboratory in Eichenau, Germany. The results were compared to a Josephson-System with standard liquid helium based cooling.  The direct comparison of both systems showed an impressive agreement better than 1 part in 10-10.  The successful operation of a dry-cooled AC-Quantum Voltmeter is considered a tremendous milestone in completing the team’s objective: The development of the World’s first fully operational, Josephson based Quantum-Calibrator. 
esz – a EURAMET partner
esz AG is partner in the latest EURAMET (European Association of National Metrology Institutes) research project “Waveform metrology based on spectrally pure Josephson voltages”. The objective is the continuous improvement of a user-optimized Josephson Arbitrary Waveform Synthesizer (JAWS). A refined JAWS enables quantum exact AC measurements up to 1000 V and 1 MHz. esz is considered the industrial voice among scientifically oriented NMIs. Thus, esz will focus on requirements such as usability, performance, efficiency. The project is a PTB (Germany’s National Metrology Institute) led initiative earmarked for 2 years and budgeted for 2 million Euros. esz is one of two commercial partners among 11 European NMIs. The EURAMET project “Automated impedance metrology extending the quantum toolbox for electricity” was completed in early 2016. The project successfully refined impedance measurement procedures and conducted detailed usability and performance tests of a cutting edge impedance simulator and impedance bridge. The latter, a METAS (Swiss national metrology institute) prototype, is set to revolutionize standards and procedures in terms of accuracy and versatility.
