Cryo-CMOS Electronics for Quantum Computing Applications

Edoardo Charbon

Quantum computers hold the promise to solve some of the most complex problems of today. The core of a quantum computer is a quantum processor, which is composed of quantum bits (qubits). Qubits are fragile and their state needs to be corrected in real time ...

Transient Impedance of Interconnected Wind Turbine Grounding Systems

Marcos Rubinstein, Antonio Sunjerga, Qi Li

Wind turbines are very vulnerable to lightning because of their height, sharp edges and remote locations often with low soil conductivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We anal ...

A dynamic-relaxation formulation for analysis of cable structures with sliding-induced friction

Ian Smith, Nizar Bel Hadj Ali, Ann Christine Sychterz

In many cable structures, special types of joints are designed to allow cables to slide freely along the joints. Thus, a number of discrete cable elements are substituted by a single continuous cable that slides over multiple nodes. Continuous cables are e ...

Quench Level of the HL-LHC Nb3Sn IR Quadrupoles

Luca Bottura, Enrico Felcini

The scope of the Large Hadron Collider Hi-Lumi Project at CERN includes the installation of several superconducting magnets wound with Nb3Sn Rutherford cables. The quench level of these magnets (i.e. the maximum energy that a cable can tolerate without que ...

Inkjet Printing of Functional Polymer Composites for Chemiresistive Gas Sensors

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

Drop-on-Demand Inkjet printing can be used as an effective technique to deposit the sensing layer in chemiresistive gas sensors. In this type of gas sensors, a composite containing an insulating polymer mixed with a conductive filler is used for sensing an ...

Experimental Characterization of the Response of an Electrical and Communication Raceway to IEMI

Marcos Rubinstein, Nicolas Mora Parra

This paper reports the results of two experimental campaigns aimed at studying the high-frequency response of a raceway containing low voltage power, telephone, and Ethernet cables, to external electromagnetic field illumination. The raceway was tested aga ...

Contribution to the study of the vulnerability of critical systems to Intentional Electromagnetic Interference (IEMI)

Nicolas Mora Parra

The progress of high power electromagnetic (HPEM) sources during the late 1990s raised the concern in the electromagnetic compatibility (EMC) community that they could be deployed for criminal purposes to interfere with the operation of modern electronic s ...
