In‐Flight Observation of Gamma Ray Glows by ILDAS

“…Its main goals are to measure lightning strike parameters, to determine entry and exit points on the aircraft structure, and to assess the possible structural damage. It was comprehensively described in a series of publications (de Boer et al, ; Hervé et al, ; Stelmashuk et al, , ; van Deursen, ; van Deursen & Stelmashuk, ; Zwemmer et al, ). The ILDAS system was extended with two LaBr3 40 × 40 mm 2 cylindrical scintillation detectors.…”

“…The ILDAS system contains one electric field sensor ( E field) and eight magnetic field window sensors ( H field). Photographs of the system and operational details can be found in Kochkin et al () and van Deursen (). Both sensors are differentiating, and subsequent analog integration provides a flat response over the frequency band from 100 Hz to 10 MHz for H field and 10 Hz to 500 kHz for E field.…”

In-flight measurements of energetic radiation from lightning and thunderclouds

“…A is of the same order as the window surface; the analytical solution for a circular window with radius r w is A = r 2 w . A numerical analysis of the window sensor takes the actual shape of the window and the mounting flanges into account [56,54]. Measured and calculated values agreed better than 5% for an aircraft with a thin metallic hull such as an Airbus A320 [54].…”

“…A numerical analysis of the window sensor takes the actual shape of the window and the mounting flanges into account [56,54]. Measured and calculated values agreed better than 5% for an aircraft with a thin metallic hull such as an Airbus A320 [54]. The horizontal wire makes the sensor respond to the horizontal component of the current density K 0 ; a vertical wire to the vertical component of K 0 , be it with different sensitivity because of the ellipsoidal window.…”

B-Dot and D-Dot Sensors for (Sub)Nanosecond High-Voltage and High-Current Pulse Measurements

“…Furthermore, most of the commercially available components are bulky and cannot easily be implemented in compact setups. Therefore, homemade sensors such as D-I (Differentiating-Integrating) systems, capacitive voltage probes, Rogowski coils [13]- [18] or even electro-optic probes are often employed [19], [20].…”
