  1. 1. Differential Magnetic Biosensor using HTS SQUID Gradiometer

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Sobhan Sepehri; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-Tc SQUID; magnetic bioassay; diagnostics; RCA; microfluidics; magnetic nanoparticle; point-of-care; rolling circle amplification; differential ac susceptibility; biosensor;

    Abstract : A fundamental tool for containing an epidemic outbreak and mitigating its effects is early diagnostics. Currently, most of the diagnostic tests are performed by trained staff in centralized labs, which are expensive and time-consuming to establish and operate. Lack of access to such facilities could have devastating effects. READ MORE

  2. 2. Parametric interactions with signals and the vacuum

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Michael Roger Andre Simoen; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vacuum; circuit-QED; interferometer; SQUID; dynamical Casimir effect; multimode resonator; pumpistor; mode conversion; superconducting circuits; parametric amplification;

    Abstract : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. READ MORE

  3. 3. Tunable superconducting resonators, subharmonic oscillations and manipulation of microwaves

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Ida-Maria Svensson; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; circuit-QED; tunable superconducting resonators; subharmonic oscillations; parametric oscillations; microwave manipulation; frequency down-conversion; driven nonlinear systems; superconducting resonator; SQUID; tunable resonator;

    Abstract : In this thesis I present different types of manipulations of microwave fields using tunable superconducting resonators. A resonator is made tunable by adding one or more superconducting quantum interference devices, SQUIDs. The SQUID consists of a superconducting loop with two Josephson junctions and acts as a tunable nonlinear inductor. READ MORE

  4. 4. High-Tc SQUIDs for magnetophysiology - development of a magnetometer system and measurements of evoked fields from hippocampal neurons in vitro

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Per Magnelind; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuromagnetism; brain slice; neurophysiology; electrophysiology; hippocampus; biomagnetism; SQUID;

    Abstract : This thesis concerns development of a system based on a high-transition-temperature superconducting quantum interference device (high-Tc SQUID) magnetometer. The system has been designed and used for magnetic field recordings from brain slices, i.e. magnetophysiology. READ MORE

  5. 5. Nonlinear dynamics of Josephson Junction Chains and Superconducting Resonators

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Adem Ergül; KTH.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Josephson Junction; SQUID; Superconducting Resonators;

    Abstract : This thesis presents the results of the experimental studies on two kindof Superconducting circuits: one-dimensional Josephson junction chains andsuperconducting coplanar waveguide (CPW) resonators. One-dimensionalJosephson junction chains are constructed by connecting many Superconducting quantum interference devices (SQUIDs) in series. READ MORE
