LumaCam: a novel class of position-sensitive event mode particle detectors using scintillator screens.

A new type of position-sensitive detectors is gaining attention in the neutron community. They are scintillator based detectors that detect the scintillation light on an individual photon basis via an image intensifier and a fast image sensor. Their readout operates in event mode i.

Novel high-efficiency 2D position-sensitive ZnS:Ag/LiF scintillator detector for neutron diffraction.

Scintillator-based ZnS:Ag/LiF neutron detectors have been under development at ISIS for more than three decades. Continuous research and development aim to improve detector capabilities, achieve better performance and meet the increasingly demanding requirements set by neutron instruments. As part of this program, a high-efficiency 2D position-sensitive scintillator detector with wavelength-shifting fibres has been developed for neutron-diffraction applications.

Novel Al2O3:C,Mg fluorescent nuclear track detectors for passive neutron dosimetry.

The latest advances in the development of a fluorescent nuclear track detector (FNTD) for neutron and heavy charged particle dosimetry are described and compared with CR-39 plastic nuclear etched track detectors (PNTDs). The technique combines a new luminescent aluminium oxide single crystal detector (Al(2)O(3):C,Mg) with an imaging technique based on laser scanning and confocal fluorescence detection. Detection efficiency was obtained after irradiations with monoenergetic neutron and proton beams.

Congenital defects of the inner ear in association with meningitis.

Three patients presented with meningitis associated with congenital defects of the inner ear, consisting of a cyst-like cochlea and a short, wide horizontal semicircular canal. The findings were easily identified on routine skull radiographs, alleviating the need for further studies and leading to treatment of the defect.
