SOLIS Vector Spectromagnetograph: status and science
The Vector Spectromagnetograph (VSM) instrument has been recording
photospheric and chromospheric magnetograms daily since August 2003. Full-disk
photospheric vector magnetograms are observed at least weekly and, since
November 2006, area-scans of active regions daily. Quick-look vector magnetic
images, plus X3D and FITS formated files, are now publicly available daily. In
the near future, Milne-Eddington inversion parameter data will also be
available and a typical observing day will include three full-disk photospheric
vector magnetograms. Besides full-disk observations, the VSM is capable of high
temporal cadence area-scans of both the photosphere and chromosphere.
Carrington rotation and daily synoptic maps are also available from the
photospheric magnetograms and coronal hole estimate images.Comment: 4 pages, 2 figures, Solar Polarimetry Workshop 5, PAS
Streifenabsorber als Energie sparende Schallschutzkomponente Abschlussbericht
On the basis of theoretical modelling, the acoustic properties of absorber strips were investigated in extensive measurements. Optimisation of the cover parameters resulted in well-tuned medium-frequency noise absorbers which, with appropriate protective measures, are suited for heavy-duty applications. (orig.)Auf Grundlage theoretischer Modellierungen wurde der Streifenabsorber als Schalldaempfer beschrieben und in umfangreichen Messungen untersucht. Durch Optimierung der Abdeckungsparameter wurden verschieden abgestimmte mittelfrequent wirksame Schalldaempfer mit hoher Daempfung erreicht. Geeignete Schutzmassnahmen ermoeglichen die Anwendung unter harten Einsatzbedingungen.
