Prototype developments for a high-resolution neutron detector at RB
A detector for momentum measurements of highenergy neutrons in the energy range 200 MeV to 1000 MeV is being developed for the RB experiment at FAIR. The detection principle is based on a combination of converter material and subsequent detection of charged particles from reactions in the converter material. Multigap Resistive-Plate Chambers (MRPC) are used for the detection of charged particle...
متن کاملPhytoestrogens: recent developments
Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
متن کاملThe Compressed Baryonic Matter Experiment at FAIR: Progress with feasibility studies and detector developments
The Compressed Baryonic Matter (CBM) experiment is being planned at the international research center FAIR, under realization next to the GSI laboratory in Darmstadt, Germany. Its physics programme addresses the QCD phase diagram in the region of highest net baryon densities. Of particular interest are the expected first order phase transition from partonic to hadronic matter, ending in a criti...
متن کاملRecent Developments in Detector-Based Photometry and Future Needs in Photometry
In the early history of photometry, sources such as candles, lamps, or blackbodies were always used as standards to realize, maintain and transfer the photometric base unit. Even after the advent of photodetectors in the early twentieth century, lamps have been traditionally used to maintain and transfer the units of luminous intensity and luminous flux. In this case, a group of primary standar...
متن کاملDevelopments in High-Performance HPGe Detector Spectrometer Systems for Safeguards Applications
Both fixed and portable safeguards applications place stringent demands on spectrometer systems. Instruments must perform well spectroscopically despite operation in harsh environments. Resolution and stability requirements for Pu isotopic systems hardware are based on the complexity of the spectrum and the necessity for the analysis software codes to use multipeak regions of the spectrum. Bett...
