TPS Launches the Transient Plasma Surface Treatment System, Delivering Major Benefits Through Nanosecond Pulsed-Power Plasma

 

The room-temperature, open-environment treatment system unlocks new versatility and efficiency for thin-film coating, surface cleaning, and activation of a wide variety of substrates.

 
TORRANCE, California, October 23, 2019 — Transient Plasma Systems Inc. (TPS), which develops nanosecond pulsed-power systems for a wide range of applications, today announced the launch of its Transient Plasma Surface Treatment System. This highly versatile and efficient new system supports open-environment surface cleaning, activation, and thin-film coating of many different types of substrates, including wide-area and temperature-sensitive surfaces.

Using repetitive nanosecond pulses, the Transient Plasma Surface Treatment System delivers energy more effectively than competing solutions using kHz or MHz excitation. The system’s unique benefits include the ability to produce a low-temperature plasma stream, precise control of plasma energy, low sensitivity to working distances, and the ability to produce anything from a narrow beam to a wide uniform curtain of plasma.

How the Transient Plasma Surface Treatment System delivers superior versatility

The wide plasma beam produced by the Transient Plasma Surface Treatment System makes it ideal for uniform treatment of wide-area substrates such as fabrics and plastic films. The system’s low sensitivity to working distances reduces the need for sophisticated automation, enabling applications that benefit from handheld operations and enhancing the ability to handle parts with complex shapes and uneven substrates.

The Transient Plasma Surface Treatment System is uniquely qualified for applications that require uniform and high-integrity thin-film coatings, such as bio-medical, aerospace, and other industrial use cases. Because it generates more-effective plasma and minimal heat in the output beam, the nanosecond pulsed-power plasma system is exceptionally well-suited for treating temperature-sensitive substrates such as human tissue, delicate structures, textiles, and thin polymeric membranes.

“We are excited to launch our technology in the atmospheric plasma processing space,” said Dan Singleton, CEO of Transient Plasma Systems. “We believe it will help unlock new capabilities in several areas of surface treatment.”

Fraunhofer testing: Expert evaluation and results

Over the past several months, TPS’ Transient Plasma Surface Treatment System has been evaluated by the world-renowned Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Germany.

“Our testing of the TPS nanosecond pulsed-power plasma system demonstrated the ability to precisely control plasma energy, making the system very attractive for thin-film coating applications, including those using precursors with complex molecules,” said Dr. Uwe Lommatzsch, senior researcher at Fraunhofer IFAM. “The system’s low sensitivity to working distances make it interesting for applications such as conformal coating of electronic PC board assemblies. The wide plasma beam is a very exciting feature of the TPS system, and it can play a vital role in improving process throughput. We believe that this system has several salient characteristics that will benefit bonding and coating applications, including transitioning some current low-pressure plasma applications to atmospheric.”

In order to provide superior tunability for process results, TPS’s new compact pulse generator powers atmospheric-pressure plasma over a wide range of voltages and repetition rates. The solid-state design provides efficiency and unmatched durability. Details about the TPS Transient Plasma Surface Treatment System can be found here: tpsplasma.com

Swapping spark plugs for nanopulses could boost engine efficiency by 20%

More precise ignition events mean better fuel efficiency and fewer pollutants.

Here in 2019, only the most fringe reactionaries are able to claim with a straight face that climate change is not a thing. But after years of the media doing its “two sides” thing, recalcitrant policy makers dragging their heels, a continued lack of investment in public transport, and intense, well-funded opposition from vested interests like the oil industry, there has been a heavy cost on attempts to decarbonize. When it comes to the transportation sector, even with the best will in the world, it will be decades before we see the end of the internal combustion engine. So when a new technology comes along that offers a really meaningful improvement in fuel efficiency when fitted to existing engines, my interest gets piqued. Such is the case with a new ignition system from a company called Transient Plasma Systems.

The company has its roots in pulsed power technology developed for the Department of Defense at the University of Southern California, specifically nanosecond-duration pulses of power. Since 2009, it has been working on commercializing the technology for the civilian market in a number of applications, but obviously it’s the automotive one that interests me.

In a conventional four-stroke internal combustion gasoline engine, which works on the principle of suck-squeeze-bang-blow, the bang is created by a spark plug igniting the fuel-air mixture in the cylinder. That spark typically lasts several milliseconds, and although the control of that spark is now controlled electronically rather than mechanically, the principle is the same today as it was in 1910 when Cadillac added it to its engines.

TPS’s system does away with the conventional coil-on-plug approach. Instead, much shorter pulses of plasma—several nanoseconds—are used to ignite the fuel-air mix inside the cylinder. These have a much higher peak power than a conventional spark; thanks to their much shorter duration, however, the ignition is actually still rather low-energy (and therefore lower temperature).

Consequently, it’s possible to achieve better combustion at high compression ratios, more stable lean burning, and lower combustion temperatures within the cylinder. And that means a more efficient engine and one that produces less nitrogen oxide. TPS says that using its system, it can increase the thermal efficiency of an already very efficient internal combustion engine like the one Toyota uses in the current Prius (which is ~41 percent) up to 45 percent—similar to the turbulent jet ignition systems that have recently seen Formula 1 gasoline engines reach that level.

What makes this tech really cool—at least to me—is that TPS has designed the system to be drop-in for existing spark plugs, so OEMs don’t have to redesign their engines to use it. And on top of that, there’s no reason it can’t work in combination with other recent advanced engine technologies like Delphi’s dynamic skip fire (which allows highly accurate cylinder deactivation), Nissan’s variable-compression ratio engine, or even Mazda’s clever Spark Controlled Compression Ignition system.

Although it’s designed as a drop-in system, forget about fitting it to your own car—TPS’s going-to-market strategy is to work with an established tier-one supplier to leverage existing relationships with OEMs as well as existing manufacturing capacity. TPS told me it’s a little too early to get specific about the cost of its system versus conventional spark ignition but that the fuel economy gains it would deliver should please the OEM beancounters who weigh up things like expected fuel efficiency versus production cost.
