Performance of adiabatic melting as a method to pursue the lowest possible temperature in $^3$He and $^3$He-$^4$He mixture at the $^4$He crystallization pressure

Autor: Riekki, T. S., Sebedash, A. P., Tuoriniemi, J. T.

We studied a novel cooling method, in which $^3$He and $^4$He are mixed at the $^4$He crystallization pressure at temperatures below $0.5\,\mathrm{mK}$. We describe the experimental setup in detail, and present an analysis of its performance under va

Report

Thermal conductivity of superfluid $^3$He-B in a tubular channel down to 0.1$T_c$ at the $^4$He crystallization pressure

Autor: Riekki, T. S., Tuoriniemi, J. T., Sebedash, A. P.

We studied the thermal conductivity of superfluid $^3$He in a 2.5 mm effective diameter and 0.15 m long channel connecting the two volumes of our experimental assembly. The main volume contained pure solid $^4$He, pure liquid $^3$He and saturated liq

Report

Thermodynamics of adiabatic melting of solid $^4 \mathrm{He}$ in liquid $^3 \mathrm{He}$

Autor: Riekki, T. S., Sebedash, A. P., Tuoriniemi, J. T.

Publikováno v: Phys. Rev. B 99, 054502 (2019)

In the cooling concept by adiabatic melting, solid $^{4}$He is converted to liquid and mixed with $^{3}$He to produce cooling power directly in the liquid phase. This method overcomes the thermal boundary resistance that conventionally limits the low

Effects of $^4$He film on quartz tuning forks in $^3$He at ultra-low temperatures

Autor: Riekki, T. S., Rysti, J., Mäkinen, J. T., Sebedash, A. P., Eltsov, V. B., Tuoriniemi, J. T.

In pure superfluid $^3$He-B at ultra-low temperatures, quartz tuning fork oscillator response is expected to saturate when the dissipation caused by the superfluid medium becomes substantially smaller than the internal dissipation of the oscillator.

Thermodynamics of adiabatic melting of solid He 4 in liquid He 3

Autor: Riekki, T. S., Sebedash, A. P., Tuoriniemi, J. T.

In the cooling concept by adiabatic melting, solid He4 is converted to liquid and mixed with He3 to produce cooling power directly in the liquid phase. This method overcomes the thermal boundary resistance that conventionally limits the lowest availa
