The Technological Laboratory of LMU is undergoing major changes. Most important of them is raising a DLC-Factory’s for diamond-like-carbon (DLC) foils production and a shutdown of the Hot-Lab Facility. Current Laboratory status and development plan

Measuring the resonance strengths of the 25Mg(p,γ)26Al reaction at energies of astrophysical interest poses a very difficult task for the usual prompt γ-ray detection method. Here we describe an alternative method in which targets are first irradia

Radioactive thin film targets have been prepared by high vacuum evaporation–condensation in the hot-lab facility of the University of Munich. Targets made by this technique are of high density and excellent smoothness, being well suited for experim

Production of HgS targets, based on HgO, is described. The HgS is precipitated from HgO dissolved in diluted HNO3 by gaseous H2S. Subsequently the target is manufactured by evaporation–condensation of HgS in vacuum. This way the 204HgS layers of 50

We have used synchrotron radiation in order to determine the mass densities and the elemental composition of single and multilayered solid films. Soft X-rays were used to measure the spectral transmittance in a certain photon energy range, i.e. betwe

Optical filters have been developed for the X-ray astronomy project XMM (X-ray Multi Mirror Mission) [1] of ESA, where specific CCDs will serve as focal plane cameras on board the observatory. These detectors are sensitive from the X-ray to the NIR (

Charge coupled device (CCD) detectors are sensitive from the X-ray to the NIR (near infrared) region. For X-ray and soft X-ray observations in astronomy, an optical filter has to be placed in front of the CCD to suppress the UV (ultraviolet) and VIS

Experience using a high vacuum sputter deposition system over a two year period has shown it to be a reliable, economical way to prepare isotopically enriched targets. The present paper gives a survey of the many types of samples prepared so far and
