Status of the KATRIN experiment
نویسنده
چکیده
The aim of the Karlsruhe Tritium Neutrino experiment-KATRIN-is the direct measurement of the anti-neutrino mass with a sensitivity of 200 meV/c 2 (90% C.L.). It is based on the study of the endpoint region of tritium β decay where a non-vanishing anti-neutrino mass causes a distortion of the β spectrum. KATRIN will allow to probe a part of the cosmology-relevant neutrino mass parameter space and hence further constrain cosmological models and help to clarify the role of neutrinos as dark matter. KATRIN uses a windowless gaseous tritium source for production of β electrons in combination with an electrostatic filter for energy analysis. An overview of the status of the KATRIN experiment will be given.

KATRIN: an experiment to determine the neutrino mass from the beta decay of tritium
for the KATRIN Collaboration Abstract KATRIN is a very large scale tritium-beta-decay experiment to determine the mass of the neutrino. It is presently under construction at the Karlsruhe Institute of Technology north campus, and makes use of the Karlsruhe Tritium Laboratory built as a prototype for the ITER project. The combination of a large retarding-potential electrostatic-magnetic spectrom...
متن کاملFrequency Matters: Pitch Accents and Information Status
This paper presents the results of a series of experiments which examine the impact of two information status categories (given and new) and frequency of occurrence on pitch accent realisations. More specifically the experiments explore within-type similarity of pitch accent productions and the effect information status and frequency of occurrence have on these productions. The results indicate...

This experiment was carried out to determine the effects of turmeric, cinnamon, ginger and garlic powder on mixed sex Cobb-500 broilers performance, serum antioxidant status, and serum thyroid hormones. Heat stresses were created by increasing ambient temperature to 32-34 ˚C from 12: a.m. to 16: p.m. during days 31-42 of the experiment. Blood serum samples were obtained from 6 broilers of each ...

The Karlsruhe Tritium Neutrino Experiment (KATRIN) aims to determine the absolute mass of the electron antineutrino from a precise measurement of the tritium β-spectrum near its endpoint at 18.6 keV with a sensitivity of 0.2 eV/c. KATRIN uses an electrostatic retardation spectrometer of MAC-E filter type for which it is crucial to monitor high voltages of up to 35 kV with a precision and long-t...

The experiment described in this paper tests for the perceptual magnet effect within the categories of high and low boundary tones in German, referring to question and statement, respectively. The experiment is based on previous work in which the categorical status of the two German boundary tones had been evaluated. The results found there showed that there was a discrimination ability within ...
