THE TEAM 2 2MESSAGE BY THE A P PRESIDENT WE ALWAYS FIND THAT IT IS EASY... WHAT WE ALREADY KNOW

2 2Our A P is putting forward the first Pulsed Power made Public Workshop, on thNovember 20 , to show that Pulsed Power is not Rocket Science and is really useful.

We will talk about different aspects of the technology and applications, making sure that everybody has access to this information.

The principle is "Make it Simple". Because you don't need to make all the mistakes that someone has made before!

So we are preparing a set of Tutorials that will address some basic concepts of technology related to pulse generation, as well as practical applications in the food, environment and health sectors. Things such as, how to apply Pulsed Electric Fields in food stuff and why, how to make non thermal plasma and how to cut and deform metals with a magnetic field.

Is going to be fun! And if you have any ideas and want to participate, please join us.thJoin us on November 20 !

Oct 2018The A²P² Newsletter will be available

on a quarterly frequency

2 2We here at A P have decided to occasionally invite a guest editor and I am honoured to

have been given this opportunity as the first guest.2 2 A P is inspiring the Pulse Power conversation. Researchers, Entrepreneurs and

education institutions with varied backgrounds that range from natural sciences to humanities and from medicine to engineering are reaching out to us are selected. And from everywhere really, Australia, USA, Europe, South America and Asia. Typically, the majority are academics who are under career pressure to share views and conversations with colleagues in the field.

Young Academics are keen to join cross-disciplinary conversations. Whatever the reason, we are now contributing to the conversation and I consider that a

2 2sign of success. Here at A P we have quite exact ambitions. To be careful and transparent in the membership-selection processes that value diversity; a size and structure that enable the organization to think and act big, while not being so large that members may lose connection to each other and to the whole (typically 50 to 200 members, with secretarial support; the inaugural; and autonomy for the association to set its own agenda. WE want to do things that benefit YOU. That is why on November 20 we will hold a workshop on soft skills and particularly focusing live communication and presentations which I know you are all much in need of. We are aware that great presentation skills, be it to colleagues, students, at conferences or to potential investors are of major importance. We encourage the first members to be bold and join us. And you can tell us what else you would like us to organize workshops on and we will

2 2stream them. A P could become an important development tool in your life. You will be warmly 2 2welcomed to the A P family and the global network. Visit our website and see what our aims

and objectives are and hopefully it will spur you to become a major participant in this worldwide effort to spread the benefits of scientific developments, in their broadest sense, to all.

We also invite you to register for our first of a series of workshops on Soft Skills. Each one th

will be dedicated to a different topic and the first on 20 November will be on Strategic Networking - Building a Professional Circle.

CHALLENGES FOR THE APPLICATION OFPULSED POWER IN THE INDUSTRY - THEFOOD SECTOR EXAMPLE

Nowadays Pulsed Power is making its way through commercial applications, in traditional sectors such as material engineering, environment and the food industry but also in new areas such as health and microbiology. Almost every week a new application of Pulsed Power can be found in specialized scientific journals and new Pulsed Power equipment is installed in a factory.

From its roots, in military and large physics applications, with megawatt hard-tube single pulse systems, to the recent kilowatt semiconductor based efficient repetitive pulse systems, Pulsed Power has been both an image and also a key-drive of technological progress. Whilst the goal has always been the same, enhancing a product or a process and most of the time with energy efficiency.

The PEF “must haves ” and the renting optionHowever the route is still very demanding as industry sets high requirements on

Pulsed Power systems, the most common being: electrical efficiency, reliability, low cost, reduced size, portability and on top of these the equipment must comply with the safety and electromagnetic compatibility regulations. In addition, as is the case of the food industry, further difficulties arise from two specific aspects: i) first it is a highly-regulated sector and; ii) it is very complex to identify improvements in industrial environments. In addition, some times the processed materials are not available all the year round, as in seasonal materials such as grapes and olives, where the available period to process can be just a few weeks, which can make renting, instead of selling, a good option.

Show that it works Then, the need for careful design of tests is crucial; in order to introduce the Pulsed

Power systems in the correct industrial step to achieve the wanted result. For the food sector, normally pulsed electric fields are used, so a treatment chamber, or transducer that converts the voltage pulses to pulse electric field applied to food in-line with the existing processes is needed.

One possible solution is that in order to mitigate some of the industrial hurdles for the food sector and at the same time have the opportunity to demonstrate the benefits of the technology to a specialized audience, is to integrate the Pulsed Power system in an available Pilot Plant that simulates the industrial process but where most of the steps of the process can be better controlled, producing also more precise diagnostics.

In conclusion, the mission of transferring this technology to the industry needs resilience and a good understanding of the industrial process, also because although everyone is always looking for a Wow effect, most of the times a 5% yield increase or energy reduction can make an industrial happy, but you need to prove it.

The SIAME laboratory of the University of Pau is divided in two teams. The High Voltage Processes team is led by Professor L. Pecastaing. It is one of the few French university teams working in the field of high voltage and the only one in the field of High Pulsed Power (HPP). This team includes 12 teacher-researchers, 1 research engineer and 9 PhD students currently enrolled. The main topics currently being developed at SIAME are related mainly to the generation and metrology of high voltage and / or current pulses. Our main applications are flash radiography, pulse electroporation, high-power microwave sources, rock fracturing, and especially high-power lasers.

The SIAME laboratory has developed different types of high voltage transient sources (Marx generators, Blumlein, pulse resonant transformers, transmission line transformers) which have complementary characteristics. Also a 100 kJ energy bank is dedicated for dynamic pressure wave generation in fluids. These different sources have been developed, most of the time, under industrial contracts (DGA, CEA, Total, ITHPP, ABB, ISL, Effitech...).

In the framework of studies conducted by the CEA in the domain of HPP systems for Defense applications, the SIAME was identified 10 years ago as a unique French university partner in this field. The level of training and specificity in HPP provide the SIAME laboratory as a unique place in terms of building pools of young people with real expertise in this area. In 2017 a common laboratory between SIAME and the CEA has been created: the SAGE laboratory. It brings together about 30 researchers working in the field of HPP. His research interests are related to the development of high pulsed power systems (devices involving very high power, compact, reliable and sometimes autonomous).

The SIAME thus has a capacity of expertise and a unique know-how at the French university level in the field of fast high voltage pulse generators, whether in their design, implementation or test.
