Driving a low critical current Josephson junction array with a mode-locked laser
J. Nissila, T. Fordell, K. Kohopaa +11
We demonstrate the operation of Josephson junction arrays (JJA) driven by optical pulses generated by a mode-locked laser and an optical time-division multiplexer. A commercial pho…
The airglow layer emission altitude cannot be determined unambiguously from temperature comparison with lidars
Tim Dunker
I investigate the nightly mean emission height and width of the OH*(3-1) layer by comparing nightly mean temperatures measured by the ground-based spectrometer GRIPS 9 and the Na l…
On temporal correlations in high-resolution frequency counting
Tim Dunker, Harald Hauglin, Ole Petter Rønningen
We analyze noise properties of time series of frequency data from different counting modes of a Keysight 53230A frequency counter. We use a 10 MHz reference signal from a passive h…
