- Die doppelt-differentielle Neutronenausbeute der Reaktion 9Be+d bei einer Deuteronenenergie von 3 MeV
Quellterm für thermischen Standard des NPL bestimmt. - Design and Manufacture of a TCAP Scattering Chamber
To determine the fluence of monoenergetic neutrons by means of the time-correlated associated particles method (TCAP), a low-mass scattering chamber has been developed and manufactured. It is intended to be operated at PTB's ion accelerator PIAF. - Measurement of the differential neutron/deuteron scattering cross section in the energy range from 100 keV to 600 keV by means of a recoil-proton proportional count
Besides the nucleon-nucleon scattering, the scattering of a neutron on a deuteron – i.e. on a nucleus of the heavy hydrogen atom 2H consisting of a neutron and a proton – is one of the fundamental processes in quantum-mechanical few-body systems. - Light yield function of a liquid scintillator for neutrino detection in the underground experiment SNO+
The SNO+ detector is to be used to investigate diverse aspects of neutrino physics. The detector consists of a liquid scintillator tank of 12 m in diameter in which the neutrino-induced events are detected by approx. 10,000 photomultipliers. For the liquid scintillator, linear alkylbenzene (LAB) is used as a solvent, and 2,5-Diphenyloxazole (PPO) is used as primary scintillator. Within the scope of a cooperation between the Technische Universität Dresden (TUD), the Brookhaven National Laboratory (BNL), and PTB, the proton light yield from the pulse height spectrum generated by monoenergetic neutrons was determined using PTBxs time-of-flight spectrometer, and investigated for different combinations of solvent, primary scintillator and other components.
