Castle, "Experimental study of the characteristics of Trichel pulses in the needle-plane negative corona discharge in atmospheric air", J. Electrostatics 88 (Aug 2017) 49-54. Abstract only (paywall). Abstract [web]: - Setup: air, room temperature, atmospheric pressure; four needles with tip radii 19-55 um; gap 6 mm to 3 cm; voltage from onset (-4 to -6 kV) up to -10 kV. - Rise time, fall time and pulse width were "not a function of" tip radius, voltage or gap. - Results were compared with numerical simulation and with Lama and Gallo. The findings were "in a good agreement with Lama's and Gallo's work"; "Some discrepancies were found between the numerical and experimental results". Bearing: the same Western group's own experimental follow-up to the ESA 2010 model (priority 1-2). It bears on claims 4-5, and on the missing rise-time and width comparison noted in the deep read. Note the measured onset of -4 to -6 kV with 19-55 um tips, against Gallo's reported -2.3 kV that does not depend on radius (thesis Ch. 8). The two experimental records differ on onset.
