A new era of spectroscopy: SINFONI, NIR integral field spectroscopy at the diffraction limit of an 8m telescope

SINFONI, the SINgle Faint Object Near-infrared Investigation, is an instrument for the Very Large Telescope (VLT), which will start its operation mid 2002 and allow for the first time near infrared (NIR) integral field spectroscopy at the diffraction limit of an 8-m telescope. SINFONI is the combination of two state-of-the art instruments, the integral field spectrometer SPIFFI, built by the Max-Planck-Institut fuer extraterrestrische Physik (MPE), and the adaptive optics (AO) system MACAO, built by the European Southern Observatory (ESO). It will allow a unique type of observations by delivering simultaneously high spatial resolution (pixel sizes 0.025arcsec to 0.25arcsec) and a moderate spectral resolution (R~2000 to R~4500), where the higher spectral resolution mode will allow for software OH suppression. This opens new prospects for astronomy.Comment: 9 pages, 4 figures, to appear in SPIE proceedings "Astronomical Telescopes and Instrumentation 2000".

Imaging the Universe in 3D with the VLT: The Next Generation Field Spectrometer SPIFFI

We present SPIFFI, the integral field spectrometer for the VLT. This instrument allows simultaneous observation of infrared spectra in more than 1000 image points of a two dimensional field. With its set of four gratings and a pixel scale that can be varied by a factor of ten, SPIFFI provides high flexibility, and at the same time offers the unique possibility of diffraction limited imaging spectroscopy at an 8m-class telescope, when fed by the adaptive optics system MACAO. We outline the scientific drivers for building such an instrument, the concept of image slicing, the optical design, and the implementation of SPIFFI

SINFONI - Integral Field Spectroscopy at 50 milli-arcsecond resolution with the ESO VLT

SINFONI is an adaptive optics assisted near-infrared integral field spectrometer for the ESO VLT. The Adaptive Optics Module (built by the ESO Adaptive Optics Group) is a 60-elements curvature-sensor based system, designed for operations with natural or sodium laser guide stars. The near-infrared integral field spectrometer SPIFFI (built by the Infrared Group of MPE) provides simultaneous spectroscopy of 32 x 32 spatial pixels, and a spectral resolving power of up to 3300. The adaptive optics module is in the phase of integration; the spectrometer is presently tested in the laboratory. We provide an overview of the project, with particular emphasis on the problems encountered in designing and building an adaptive optics assisted spectrometer.Comment: This paper was published in Proc.

Community Psychology in higher education in Europe: Results of a survey and discussion of the basic competency approach

This report from the Standing Committee on Community Psychology of the European Federation of Psychological Association provides an overview of higher education in Community Psychology (CP) in 14 European countries. Our findings show that 10 countries have some kind of CP teaching in their educational system. Twenty European universities offer a CP-oriented Master degree, two universities at the Bachelor level and 16 universities also have CP-oriented Ph.D. programmes. The profiles of the universities focus on two areas: Community psychology in a pure form and a combination of social psychology and community psychology. The other universities vary between clinical, organisational psychology, and a pedagogical focus. Within a certain European emphasis, these universities are analysing and changing the social conditions of community life and mental health. The responding universities failed to report adequately on comprehensive core competences and key elements in CP. To compensate for this deficit, the Standing Committee on Community Psychology proposes to develop a primer of basic CP competences for inclusion in programmes like EuroPsy

Developments in transducer stems for mechanical coupling measurements in endoprosthetics

Earlier works, here briefly summarized, described the experimental techniques used for the stress analysis of the stem-femur coupling. Special strain-gauge transducers were constructed in the shape of endoprosthesis stems, to be implanted in test femurs. Four types of such transducers have been evolved, in order to overcome problems encountered during tests. The transducers are described, and results obtained with the third of these are shown in detai
