This case study describes an investigation into failures of fuel float switches in aircraft. Over the course of the investigation, four potential failure scenarios were identified but ultimately proved to be "red herrings" or misleading. Through a process of elimination and further testing, the true root cause was determined to be solder creep in the electrical connections of some switches. Solder creep had led to failure of the joints through incremental deformation over many load cycles. This root cause was only identified after reconsidering assumptions made early in the investigation.
The document describes a proposed design for trapping and imaging rubidium-85 ions using near-field scanning optical microscopy techniques. The design involves using three orthogonal laser beams to form an optical molasses trap for cooling rubidium ions. This trap will be assisted by an anti-Helmholtz coil pair to create a magneto-optical trap. Tapered optical fibers etched with hydrofluoric acid will be used as probes in near-field scanning optical microscopy to detect and image the trapped ions with high resolution. Fluorescence detection of the trapped ions will aim to optimize the signal-to-noise ratio using lock-in amplification.
