Measuring the Kapitza Resistance between a Passivated Semiconductor and Liquid Helium

Autor: Mohammadian, Babak, McCulloch, Mark A., Gilles, Valerio, Sweetnam, Thomas, Piccirilo, Lucio

In this paper, we describe an experimental investigation into the effect of passivation layer thickness on heat dissipation between a quartz substrate and liquid helium. We have observed that by depositing SiN from 0 to 240 nm, the Kapitza resistance

Parametric amplification via superconducting contacts in a Ka band niobium pillbox cavity

Autor: Gilles, Valerio, Banys, Danielius, McCulloch, Mark A., Piccirillo, Lucio, Sweetnam, Thomas

Superconducting parametric amplifiers are commonly fabricated using planar transmission lines with a non-linear inductance provided by either Josephson junctions or the intrinsic kinetic inductance of the thin film. However, Banys et al. [1] reported

In this paper we describe QUBIC, an experiment that will observe the polarized microwave sky with a novel approach, which combines the sensitivity of state-of-the art bolometric detectors with the systematic effects control typical of interferometers

A Cryogenic Ultra-Low-Noise MMIC-based LNA with a discrete First Stage Transistor Suitable for Radio Astronomy Applications

Autor: McCulloch, Mark A., Melhuish, Simon J., Piccirillo, Lucio

In this paper a new design of MMIC based LNA is outlined. This design uses a discrete 100-nm InP HEMT placed in front of an existing InP MMIC LNA to lower the overall noise temperature of the LNA. This new approach known as the Transistor in front of
