Pulsed neutron beams available at the ISIS spallation source offer diverse possibilities for materials characterization using diffraction and imaging. In this paper, we review a range of applications of the time-of-flight neutron diffraction for the characterization of phase transformations and residual stress states in industrially-relevant situations. The setup of the ENGIN-X instrument at ISIS is described, followed by a series of case studies based on the recently obtained results.

During conventional endoscopic laser treatments, it is difficult to keep distance between target tissue and fiberscope tip for effective laser irradiation. Moreover, the choice of laser power and diagnosis of a successful procedure depend on the operator's skill or instincts. Therefore, we developed a new minimally invasive laser device using a 1.1 mm in diameter composite-type optical fiberscope (COF) to overcome the above problems. This device enables transmission of 50 W Yb fiber laser and an image in parallel. In addition, this COF enables the measurement of the blood-flow of target tissue and estimates of the distance between irradiation area and the fiber tip in real time by means of an embedded laser Doppler blood-flow meter. In this paper, we present a configuration of the minimally invasive laser device using the 1.1 mm COF and the results of the basic performance experiments.
