Review of Scientific Instruments, 2016 We have constructed an apparatus to study DC electrical breakdown in liquid helium at temperatures as low as 0.4 K and at pressures between the saturated vapor pressure and ∼600 Torr. The apparatus can house a set of electrodes that are 12 cm in diameter with a gap of 1–2 cm between them, and a potential up to ±50 kV can be applied to each electrode ...

Elementary Derivation of the Nyquist Criterion for Fractional-Order Feedback Systems
IEEE Open Journal of Circuits and Systems, 2021 It is shown that the classic Nyquist criterion can be extended in a straightforward way to feedback systems of fractional order. The proof of this extension merely requires basic notions of vector analysis and of closed-loop system transfer functions ...

A New Method for Searching for Free Fractional Charge Particles in Bulk Matter [PDF]
, 2000 We present a new experimental method for searching for free fractional charge in bulk matter; this new method derives from the traditional Millikan liquid drop method, but allows the use of much larger drops, 20 to 100 mm in diameter, compared to the ...
