PTB-News 2.2018

Dietmar Drung, Hansjörg Scherer, Martin Götz, Eckart Pesel
These staff members of departments 7.2, Cryophysics and Spectrometry, (D. Drung) and 2.6, Electrical Quantum Metrology, (H. Scherer, M. Götz, E. Pesel) have won this year's Helmholtz Prize in the category “Precision measurements in applied metrology”. They have been given this award for the development of a new current amplifier, the Ultrastable Low-Noise Current Amplifier (ULCA) and the associated current comparator which enables the traceable and highly accurate calibration of the ULCA. The Helmholtz Prize is the most significant German metrology prize; it is awarded for exceptional work in the field of high-accuracy measurement in physics, chemistry and medicine.

Ekkehard Peik The head of department 4.4, Time and Frequency, was awarded the European Frequency and Time Award 2018 at the 32nd European Frequency and Time Forum EFTF 2018 in Turin because of his “seminal contributions to single-ion optical frequency standards and high-precision spectroscopy thereby establishing most stringent limits on possible variations of fundamental constants”.

Raul Garcia Diez This staff member of the Helmholtz- Zentrum Berlin (and a former doctoral candidate at PTB) was awarded the Adlershof Dissertation Prize 2017 by the Humboldt- Universität zu Berlin, IGAFA (the scientific network representing nine non-university research institutions located in the technology park Berlin- Adlershof), and WISTA-MANAGEMENT GMBH for his doctoral dissertation which he produced at PTB's BESSY II laboratory. Raul Garcia Diez defended his thesis, “Characterization of nanoparticles by continuous contrast variation in small-angle X-ray scattering”, which received a summa cum laude distinction at the Technische Universität Berlin in April 2017.

Jan-Hendrik Hagemann This member of staff of department 4.2, Imaging and Wave Optics, has won the first Young Scientists Award given by the Competence Center Ultrapräzise Oberflächenbearbeitung (image: CC UPOB e.V.). The prize was awarded for the first time at this year's 9th High-Level Expert Meeting Asphere Metrology 2018.
