![]() ![]() A brief focus is given on a recent development of a compact and repetitive Marx generator.Īs the HPP expertise at CEA-DAM is also oriented towards enabling technologies and non-military applications in order to address key issues in various fields ranging from fundamental research to industry, few examples of recent achievements are shown to illustrate the potential of HPP for scientific and industrial applications.Įventually, this talk presents the latest HPP development on flash X-ray radiography. Pulsed power activities at CEA-DAM related to High-Power Microwave (HPM) systems for defence electromagnetic applications are also presented. It presents the specifications, technologies and performances of HPP facilities developed at CEA in order to carry out a wide variety of experimental studies to assess the resistance of engineered systems to severe environment. Then, the talk covers the contribution of HPP to the Lab-scale simulation of extreme environments (radiative and non-radiative). The main achievements in different fields of applications are reported according to a technology orientated approach.įirst this talk briefly presents the main features of the pulse power systems for the Laser MegaJoule (LMJ). ![]() This talk aims at giving an overview with an historical perspective on the HPP technologies that are currently operational or being developed at CEA-DAM. HPP technologies are generally used as key subsystems of a more complex equipment such as large accelerators or laser facilities. Random number generator ic (like how a scientific calculator generates random numbers for statistics.High Pulsed Power (HPP) system have been developed at CEA-DAM in France for the last 6 decades in order to assist with National Defence and Deterrence programmes in which they play a key role. Here's another circuit, but not truly random outputs, it just appears that way since it's driven by the 555 timer: I'm not exactly sure on the configuration of hooking up an LED with the relaxation oscillators, but I would experiment first. I would start with an experimenter board first and hook up one LED, neon bulb, capacitor and resistor with a 12V source first. Use a current limiting resistor for each LED. You just have to be sure to limit the voltage and current discharges through each LED so that you don't burn them out. Take a look at the Nothing Box by Mike Ellis:įor this application, neon bulbs would be better to use but if you still want to go with using LEDs, you would have to connect them across each group of resistor, capacitor and neon bulb group as illustrated in the above circuit and just cover the neon bulbs to cover their lighting. You can also sometimes see this flickering effect inside the orange glowing rocker switches on AC power strips from the neon bulbs inside them - after several years of use. You can see this effect on those little battery operated neon flickering candles you can get at hobby stores. Neon bulbs that flicker (due to lower pressure of neon gas inside them through their long use) probably would be ideal. It uses discharging capacitors that discharge when gas in neon bulbs ionize - which is random. The best and simplest way to produce a truly random output (that I know of) is through the use of relaxation oscillators. I like circuits like these that do things randomly. ![]()
