Establishing a process for the fabrication of high-quality HTc SQUIDs
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: High-temperature (HTc) SQUID magnetometers are used in the biomedical field of magnetocardiography
(MCG). The use of MCG enables a much earlier diagnosis of potentially dangerous
conditions than the ...
The development of a SQUID-based gradiometer
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: This thesis presents an attempt at creating a fully functional SQUID for the purposes
of a predefined application. The goal of the work is to provide a method
of development, primarily utilising the ...
Design and implementation of a RSFQ superconductive digital electronics cell library
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Rapid Single Flux Quantum (RSFQ) cells are key in the design of complex and applicable RSFQ
electronic circuits. These cells are low-level circuit elements that are used repeatedly to build
larger, ...
The fabrication of PBCO buffered step-edge Josephson junctions
(2007-03)
A major challenge in the design and operation of High Temperature Superconducting
(HTS) devices is the fabrication of reproducible Josephson junctions with good IcRn products.
One objective of this thesis was to fabricate ...
Parameter extraction of superconducting integrated circuits
(Stellenbosch : University of Stellenbosch, 2006-12)
Integrated circuits are expensive to manufacture and it is important to verify the correct
operation of a circuit before fabrication. Efficient, though accurate, parameter extraction
of post-layout designs are required ...
A 10 GHz oversampling delta modulating analogue-to-digital converter implemented with hybrid superconducting digital logic
(Stellenbosch : Stellenbosch University, 2001-03)
ENGLISH ABSTRACT: Rapid Single Flux Quantum (RSFQ) logic cells are discussed, and new cells
developed. The expected yield of every cell is computed through a Monte Carlo
analysis, and where necessary these cells are ...
SQUID detected low-field NMR for the evaluation of internal fruit quality
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Assessing the quality of fruit has become vitally important for farmers and
growers. With retailers placing ever stricter requirements on fresh produce,
growers have to spend a greater amount of time ...
A reproducible design and manufacturing process for SQUID magnetometers
(Stellenbosch : University of Stellenbosch, 2005-03)
A process was developed to design and manufacture a dc SQUID magnetometer. Superconductor
theory is given as a foundation to explain the Josephson junction. This knowledge
is applied to explain the ideal and practical ...
Fabrication of high-temperature superconducting nanobridges using atomic force microscopy
(Stellenbosch : University of Stellenbosch, 2006-12)
The Josephson effect of high-temperature superconducting nanobridge structures is
studied worldwide. Until now, nanobridges are generally fabricated with focused ion
beam milling on planar thin films. These nanobridges ...
Rapid single flux quantum very large scale integration
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Very Large Scale Integration (VLSI) of the Rapid Single Flux Quantum (RSFQ)
superconducting logic family is researched. Insight into the design methodologies used
for large-scale digital systems and ...
