Background Junction fires occur when two fire fronts merge. The rate of spread (ROS) and heat release (HRR) the junction increase more quickly than that each front, this effect exacerbated by slopes. Aims Numerical modelling an interpretation their behaviour are given examining key influencing factors. Methods Twenty physics-based simulations laboratory-scale were performed for a shrub fuel bed...

An FEL utilizing a high energy, high current and low emittance beam to prtduce radiation shorter than 2 A is investigated in this paper. This device is an extension of the previously proposed 40 A Linac Coherent Light Source based on the Stanford linear accelerator. Here we investigate the performance characteristics and parameter sensitivities of this single pass, high gain FEL amplifier opera...
