It is shown theoretically and computationally that helical magnetic field, produced by continuous winding helical coils and without the toroidal coil, can sustain MHD stable high beta plasma. Pressure driven toroidal current (bootstrap current) cancels the external magnetic field and reduces the MHD potential energy, depending on the plasma beta values. Ramp-up of heating power input induces bo...

We have integrated electronic, optical, magnetic, thermal and fluidic devices into systems to construct useful analysis tools. Over the past several years, we have developed soft lithography approaches to define microfluidic systems in which pico-Liter volumes can be manipulated. These fluidic delivery systems have more recently been integrated with optical and electronic devices. We have also ...

We study the stability of a Markovian model of electricity production and consumption that incorporates production volatility due to renewables and uncertainty about actual demand versus planned production. We assume that the energy producer targets a fixed energy reserve, subject to ramp-up and ramp-down constraints, and that appliances are subject to demand-response signals and adjust their c...

The creation of low resistivity, ultrashallow source/drain regions in MOS device structures requires rapid thermal processing (RTP) techniques that restrict diffusion and activate a significant percentage of the implanted dopant species. While current heating techniques depend upon illumination based heating, a new technology, electromagnetic induction heating (EMIH), achieves a rapid heating o...

Heating homes using gas boilers is incompatible with the UK’s target of net-zero greenhouse emissions by 2050. One solution to shift heat pumps (HPs) supplied from decarbonised power plant, but this could place an unmanageable burden on electricity supply network. National demand profiles depend heating patterns adopted households which, in turn, type system and its control. The largest data se...

A system was developed and tested to provide a deeper understanding of the fission gas release kinetics from nuclear fuel during thermal transients. Pressure, temperature, spectral data, optical images were simultaneously collected resistive sample heating, all released gases in liquid nitrogen-cooled charcoal traps. Standup testing performed with high-burnup segment rod section an average loca...

Noise studies of both the dc and ac Josephson effects have been performed on a high-T, ramp-type Josephson junction irradiated at 176 GHz. Well-established analytical results for noise in overdamped RSJs are used to model the measured I-V characteristics, and their agreement is excellent. Noise-rounded I-V curves at the critical current and the first and second Shapiro steps under coherent 176 ...

Commercial coin cells with LiNi0.6Mn0.2Co0.2O2 positive electrode material were investigated using an accelerating rate calorimeter and a Tian-Calvet calorimeter. After cycling charging to the selected states of charge (SOCs), studied under thermal abuse conditions heat-wait-seek (HWS) method heating step 5 K threshold for self-heating detection 0.02 K/min. The onset temperature rise, i.e., run...
