Abstract
This paper discusses the design and operation of thin-film thermometers and heaters for the detection and generation of second sound shock (SSS) pulses and second sound resonance (SSR) waves. The detection of quantum turbulence at multiple points along a channel is also discussed. An instrumentation package to simultaneously detect SSS pulses and induced quantum turbulence in He II has been developed. This system is able to generate and detect SSS pulses in a channel of He II while monitoring for induced quantum turbulence at multiple points along the channel. The system monitors for quantum turbulence by the attenuation of SSR waves. The experiments using this instrumentation package offer the first opportunity to directly measure the quantum turbulence time and distance evolution of SSS pulses. These experiments have applications in transient heat transfer problems in He II, such as the cooling and stability of superconductors.
