Abstract: Fluorescence Labelling This invention generally relates to techniques for fluorescence labelling, and to methods, apparatus and computer program code for processing fluorescence signal data. A method of determining respective first and second degree-of-labelling signals for different respective first and second fluorophores associated with a common entity, the method comprising: determining a first fluorescence signal from said first and second fluorophores under first conditions; determining a second fluorescence signal from said first and second fluorophores under second conditions different to said first conditions; and determining said first and second degree-of-labelling signals for said first and second fluorophores from said first and second fluorescence signals; and wherein said determining of said first and second degree-of-labelling signals is responsive to at least one coupling value (c12; c21) representing a coupling of energy between said fluorophores.

Abstract: A method of detecting fast neutrons of energy greater than 5 MeV is provided. The method includes providing a neutron detector including a plate having plurality of detection sites disposed thereon which produce an electron output. The neutron detector is directly coupled to an electron detector without an intermediate scintillator layer. The detector is positioned so that neutrons are incident on the detector and the output of the electron detector is detected.
