11. Measurement uncertainty of the secondary standard measuring facility for the water absorbed dose between 5 Gy and 25 Gy  
Date: 10.05.2006
Percental score: 8 %
The secondary standard measuring facility for the absorbed dose to water in high-energy radiation fields on the basis of Alanin/ESR could be improved by a new probes positioning device. At 5 Gy, the  
12. Determination of the water absorbed dose in neutron beams and ion beams with ionization chambers and a transportable water calorimeter  
Date: 10.05.2006
Percental score: 6 %
A transportable and compact water calorimeter was used in hospitals and research institutes which use different types of particle beams for cancer therapy: in a collimated neutron beam (Clinical  
13. Measurement of the perturbation effect correction factors pCo for flat chambers  
Date: 10.05.2006
Percental score: 10 %
For a large number of flat chambers of types Roos, Markus and Advanced Markus, the perturbation correction factors pCo were determined. As the result of these investigations, the new version  
14. Determination of the angular distribution of backscattered particles at the ion accumulation experiment  
Date: 26.09.2006
Percental score: 9 %
A monitor was developed for the measurement of sputtered and reflected particles to determine the mass contribution of particles which are backscattered through the entry hole of the collector at  
15. Pulse-driven SNS arrays for a quantum-based synthesizer for arbitrary waveforms  
Date: 01.01.2007
Percental score: 7 %
A quantum-based synthesizer for generation of AC voltages of arbitrary waveforms (Josephson Arbitrary Waveform Synthesizer, JAWS) is based on SNS Josephson junctions due to their high critical  
16. Rogowski coil used with numerical integration of the measured data  
Date: 01.01.2007
Percental score: 10 %
The apparatuses designated for the transmission of electrical energy from the power plant to the consumer are tested in a series of expensive acceptance tests before being put into operation. This  
17. Uncertainty budget for the dose range between 2 Gy and 25 Gy established  
Date: 15.01.2007
Percental score: 6 %
The uncertainty budget for the secondary standard measurement system for the dose to water based on alanine/ESR was established. The relative standard measurement uncertainty is 0.15% for 25 Gy,  
18. Operation of the ion accelerators by Department 6.4  
Date: 15.01.2007
Percental score: 8 %
The department operates two ion accelerators: a Van-de-Graaff linear accelerator and a compact cyclotron. In the period from October 1, 2005 to September 30, 2006, the two accelerators were used for  
19. Differences in the sound reduction in test facilities and in buildings  
Date: 15.03.2007
Percental score: 8 %
It was shown by scaled model measurements that in test facilities, homogeneous building elements have a larger sound reduction than in real buildings. This is a broadband effect which decreases  
20. Building Acoustics en miniature  
Date: 14.05.2007
Percental score: 6 %
Problems in building acoustics can be investigated excellently on small, downscaled models. They are more flexible, require less time and effort and are cheaper than the usual measurements carried

Search behavior

In the search, the following parameters can be used:

  • "": Phrase search. The words you entered must occur exactly as entered in the search results. Example: "Metrological Services"
  • -: NOT operation. A word can not appear in the search results. Example: "Metrological Services" -"Verification Act"
  • *: Substring search. Example: "Metrological Services" measure* finds "Metrological Services" measures and "Metrological Services" measurement

If you enter more than one search term, the individual words are connected with an "AND".
