We report on Hybrid Superconducting Quantum Interference Devices (HSQUIDs) developments and results obtained in collaboration between two laboratories of France and Turkey. HSQUIDs are superconducting devices which combine a Direct Current (DC) SQUID with a digital SQUID through a specific magnetic coupling scheme. The objective is to preserve as much as possible the ultimate and well-known sensitivity of DC SQUIDs, or analogue SQUIDs based on the Josephson tunneling effect, and combine it with a comparator-based digital SQUID relying on the Single-Flux-Quantum (SFQ) technique. This is to allow the device to work under urban environment where strong magnetic pulse can happen at times, by increasing the dynamic range of the analogue SQUID. We will present the principles of the chosen architectures, with the main properties and results, including underground measurements of the solar eclipse of 10 June 2021. We also measured the thermal noise-induced perturbations inside a closed-cycle GM cooler at 4.2K. A dynamic range of 7720 flux quanta was obtained in shielded environment, with a slew rate about 72 k∅_0/s for a sampling frequency of 100 kHz. At last we will present a detailed analysis of the specific pickup loops that were developed for the HSQUIDs.
