Integrated electronic transport and thermometry at milliKelvin temperatures and in strong magnetic fields.
We fabricated a He-3 immersion cell for transport measurements of semiconductor nanostructures at ultra low temperatures and in strong magnetic fields. We have a new scheme of field-independent thermometry based on quartz tuning fork Helium-3 viscometry which monitors the local temperature of the sample's environment in real time. The operation and measurement circuitry of the quartz viscometer...
متن کاملDirect measurement of the critical velocity above which a tuning fork generates turbulence in superfluid helium
The dynamics of an electrically-driven 8 kHz quartz tuning fork has been studied experimentally in liquid helium-4 in the temperature range 1.3< T < 4.2K under the saturated vapour pressure. The fork has relatively large dimensions compared to standard 32 kHz fork used in recent investigations. The velocity of the tip of the fork prong is measured by the indirect electromechanical equivalent me...
متن کاملApplication of the equipartition theorem to the thermal excitation of quartz tuning forks
The deflection signal of a thermally excited force sensor of an atomic force microscope can be analyzed to gain important information about the detector noise and about the validity of the equipartion theorem of thermodynamics. Here, we measured the temperature dependence of the thermal amplitude of a tuning fork and compared it to the expected values based on the equipartition theorem. In doin...
متن کاملTransition to Turbulence in a Flow Due to an Oscillating Cylinder Studied by Baker Visualization Technique
Introduction The standard Baker pH technique is used to visualize flows due to an oscillating cylinder of square crosssection in water at room temperature. Transition to turbulence is clearly indicated by the appearance of large flow structures mostly in the form of columnar vortices. The measurements are analyzed in terms of the critical Keulegan-Carpenter number versus the Stokes number and c...
متن کاملReliability of Semmes-Weinstein Monofilaments and Tuning Fork on Pressure and Vibration Sensation Measurements in Diabetic Patients
Objectives: Sensory neuropathy is the major cause of ulceration in diabetic patients. Periodical sensory examination is an appropriate method to detect neuropathy and decrease the risk of diabetic foot ulcer. Semmes–Weinstein Monofilaments (SWM) and tuning fork on/off test are widely used to assess pressure and vibration sensitivity. The present study evaluated the inter- and intra-rater reliab...
