Preamplifier for quartz tuning fork signal

Preamplifier is used for amplification of weak current signals, which are produced by quartz crystal based AFM probes, especially probes based on quartz tuning fork with voltage excitation. Preamplifier comprises a...

Quartz tuning fork: Thermometer, pressure- and viscometer for helium liquids

Commercial quartz oscillators of the tuning-fork type with a resonant frequency of 32 kHz have been investigated in helium liquids. We explore their properties in the regime of linear viscous hydrodynamic response in normal...

Experiments relating to the flow induced by a vibrating quartz tuning fork and similar structures in a classical fluid

We report on an experimental study of the behavior of a number of commercially available quartz tuning forks oscillating in a classical cryogenic fluid (liquid helium I or gaseous helium)....

Measurements of Vortex Line Density Generated by a Quartz Tuning Fork in Superfluid 4He

We present proof-of-concept measurements of the vortex line density generated by a quartz tuning fork resonator probed by the attenuation of second sound in superfluid 4He at 1.6 K. The force-velocity response of a quar...

Experiments on flow due to oscillatory motion of a cylinder of rectangular cross-section and vibrating quartz tuning fork

We extend our previous experimental studies of flow of gaseous and normal liquid cryogenic helium due to vibrating quartz forks. Measurements of the drag on prongs of the forks of different sizes and oscillation frequencies...

Cavitation in liquid helium due to a vibrating quartz fork

An experimental setup containing a quartz tuning fork inside a pressure cell in a glass helium cryostat enables us to experimentally observe effects in liquid He, which we ascribe to cavitation (as these are absent in gaseo...

Acoustic Emission by Quartz Tuning Forks and Other Oscillating Structures in Cryogenic 4He Fluids

We report on experimental investigations of acoustic emission by quartz tuning forks resonating at frequencies 32 kHz, 38 kHz, 77 kHz and 100 kHz immersed in cold gaseous 4He and its normal and superfluid liquid phases. Fre...
