Autor: Christopher D. Frost, G. Jeff Sykora, Carlo Cazzaniga, D. Raspino

Publikováno v: IEEE Transactions on Nuclear Science. 68:921-927

Gas electron multiplier (GEM) detectors and activation foils have been used for dosimetry of thermal beamlines of a pulsed neutron source. The first is an active detector that performs measurements using the time-of-flight technique, taking advantage

Publikováno v: Physica B: Condensed Matter. 551:476-479

The combination of neutron time-of-flight spectroscopy and longitudinal polarization analysis opens up the possibility of simultaneously separating cross-section components over vast regions in ( Q , Δ E ) space. In this paper, we describe initial r

Neutron activation analysis of archeological artifacts using the ISIS pulsed neutron source

Autor: Christopher D. Frost, D. Raspino, Francesco Grazzi, Antonella Scherillo, Carlo Cazzaniga, Anna Fedrigo

Publikováno v: AIP Advances, Vol 11, Iss 7, Pp 075005-075005-8 (2021)

Archeological artifacts can be analyzed after neutron irradiation at the pulsed ISIS neutron and muon source, UK, using a newly installed high purity germanium gamma ray spectrometer to perform neutron activation analysis. In this work, the details o

Polarization analysis on the LET cold neutron spectrometer using a 3He spin-filter: First results

Autor: M. Devonport, P. J. Galsworthy, D. Raspino, D. J. Voneshen, V. García Sakai, Robert Bewley, J. R. Stewart, G. Cassella, G.J. Nilsen, G. M. Paternò

We report on the design and construction of a neutron polarization analyzer based on a 3He spin filter for the LET spectrometer at the ISIS facility. Its commissioning completes the uniaxial polarized mode of the instrument. Besides the 3He spin filt
