Abstract: The present disclosure describes gain stabilization techniques for scintillation devices which do not require use of an intrinsic reference radiation source. Reference light pulses are emitted into the scintillation device to obtain a signal having a given magnitude. The magnitude of the signal is compared to the magnitude of a reference signal computed as a function of temperature and a degradation factor. A gain adjustment is computed with causes the magnitude of the signal to match the target reference magnitude. The gain adjustment is then used to adjust the system gain so that subsequent output signal amplitudes, measured when energetic photons interact in the scintillator, always correspond to the same energy.

Abstract: A method of forming tunnels(6), and tunnels formed thereby, said tunnels in one embodiment being of a form to carry transport routes (1) such as rail and road transport therealong. The method allows the tunnel to be formed from one or more access points (2) by allowing the tunnel structure (6) to be progressively extended out from the tunnel by advancing deck structures (24) along guide means (20) which are formed as part of a base structure (18). The deck structures (24) can also be used to support excavation equipment (28) and/or act as transport routes for access to the leading edge of the tunnel as it is formed. This greatly reduces the need for separate access and works to be provided adjacent to the tunnel as it is formed and therefore reduces the level of reinstatement works required after the tunnel has been formed.
