- EMAIL: cipriana@infim.ro
- FOREIGN LANGUAGES: French; English
- EDUCATION:
- M.Sc., 1972, Physics, University of Bucharest
- D.Sc.,1982, Physics, University of Bucharest ( thesis: "Study of relaxation phenomena in the hydrogen
maser" )
- EMPLOYMENT:
- Head of the Laboratory, Scientific research worker II, 1996-2004
- Head of the "Atomic Particle Trapping and Frequency Standards Group", 2004 -
- PRIZE: "Dragomir Hurmuzescu Prize" of the Romanian Academy (in 1985), for work on
the physics of the hydrogen maser
- EXPERTISE:
- Atomic and quantum physics, classical and quantum optics, experimental and theoretical, lasers,
laser atom cooling, atomic frequency standards.
- Since 1982 she is employed as a researcher at the National Institute of Laser, Plasma and
Radiation Physics, Magurele-Bucharest, Romania.
During the period 1996-2004, she was Head of the Plasma Phys. Laboratory. Since 1994 she is Head of the
Group of research on Cs frequency standards.
- In Bucharest, during 1992 and the following years she has participated in the construction of nine
hydrogen masers used by the Bucharest Observatory, the Institute of Metrology, and the Faculty of Physics.
Her work has covered subjects such as maser quantum physics, technologies such as microwave,
radiofrequency, electronics, vacuum, and atomic beams. Since 1992 she has initiated a research project on
Rb standards and laser cooling of Rb atoms.
- During the period 1992-2006, she has been employed as researcher in various national laboratories, in
particular: Observatoire de Neuchatel, Switzerland; Paris Observatory, National Bureau of Metrology-Syrte,
France; Communication Research Laboratory, Japan. At each location she has spent periods of several months
and has contributed significantly to the development of advanced state of the art atomic frequency
standards, such as Rb and Cs fountains using atom trapping techniques and laser atom cooling. These
fountains are now used by the International Bureau of Weights and Measures in the implementation of the
unit second and international time keeping.
- During her visits at national institutes she has developed expertise in all domains connected to the
opto-kinetical manipulation of atoms, in particular quantum and classical optics using solid state diode
lasers and optical fiber technology. More precisely, her work was concerned with the design of optical
benches used in the characterization of laser diodes, their spectral width, their frequency and intensity
noise; atom laser cooling; trapping of atoms in magneto-optical traps; study of static Stark effect in
atomic fountains; characterization of atomic ensembles cooled by laser radiation (atomic molasses). She
has also supported these experimental studies by means of several theoretical analyses.
- On the fundamental side, she has participated for example in the construction project of a Cs-Rb
fountain that reaches an accuracy of 10¹-16, that has permitted the setting of a 10¹-16 limit
to the drift of some fundamental constants.
- She is the author of 67 publications in scientific journals and conference proceedings. She has
participated in numerous Symposia where she has made presentations as invited speaker. She has also
been invited to make 15 conferences in Universities and National Institutes, such as the National Research
Council, Canada, the University of Bonn, Germany, the Neuchatel Observatory, Switzerland,
the Kinki University, Japan, the Polytechnic School, Montreal, and several other laboratories.
