Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown

High Voltage, EarlyView.
ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage, EarlyView.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐

High magnification optical imaging systems for the characterization of soft X‐ray focii

Journal of Synchrotron Radiation, EarlyView.
We developed compact soft X‐ray imaging systems optimized for ultra‐high‐vacuum environments, achieving micrometer‐level spatial resolution with high collection efficiency. Characterization confirmed excellent sensitivity and linearity, with applications demonstrated in caustic measurements and grating interferometry for wavefront analysis.We present a

Design and performances of a compact differential pumping unit for X‐ray beamlines

Journal of Synchrotron Radiation, EarlyView.
We present a compact differential pumping unit with apertures ≥500 µm. It allows windowless operation for in‐air sample environments as well as to connect low‐quality in‐vacuum sample environments to the beamline UHV section. The unit also protects the UHV section from accidental venting.
