Abstract
HTS Bi-SQUID elements inherently have a larger inductance due to the need for a bisecting junction. For a large single anti-peak feature in a non-uniform SQUID Array (SQA), the dimensionless screening parameter <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\beta_{L} \lt 1$</tex-math></inline-formula> is desirable. Additionally, to reduce the side lobes, a full order of magnitude spread in <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\beta_{L}$</tex-math></inline-formula> should be used. The bi-SQUID element can be used to obtain the largest area features in the distribution without having complications with elements requiring such a difference in size and thus different exposure times in the fabrication process. Additionally, several bi-SQUID elements in a large SQA can improve the linearity of the average voltage response to a varying magnetic field. We explore the successive introduction of Bi-SQUID elements to replace the largest area elements in a SQUID Array.
