Simple VUV High Pressure Gas Laser with Coaxial Electron Beam Pumping

Abstract: Vacuum ultraviolet stimulated emission of high intensity was obtained in the past by the transverse pumping of high-pressure noble gases by means of high-current relativistic electron beams. The main interest for such laser systems is their potential for obtaining high output powers with high efficiency. In general the lifetime of the upper state of these lasers is in the order of nanoseconds, so that very fast pumping is required. So far it has been reported that short pulses with high current densities were obtained by Blumlein or pulse-line circuits. From a technical point of view such a system is expensive and rather complicated. Therefore one may wonder whether in the case of small systems it is possible to obtain a sufficiently fast discharge from a Marx generator only. This is the main point of the present contribution.

Marx generator trigger loop and Marx generator

Abstract: The utility model relates to a Marx generator trigger loop and a Marx generator; the trigger loop comprises a plurality of transformers, arranged in sequence, with magnet cores; primary sides of each transformer are connected in series so as to form a common primary side; secondary sides of each transformer are mutually independent; a primary trigger signal is led in from single-point of the transformer common primary side; trigger output signals are provided by each transformer secondary side and are independent. The Marx generator uses the transformer mode trigger loop so as to effectively reduce voltage level triggering the led in signal, thus greatly improving insulation reliability of the trigger loop and safety in a device debug process.

Intelligent pulse type wireless power transmission device

Abstract: The utility model discloses an intelligent pulse type wireless power transmission device, and is a novel utility model which belongs to the technology of wireless power transmission. The intelligent pulse type wireless power transmission device can be widely used in the fields of aerospace, transportation, military and communication. The intelligent pulse type wireless power transmission device mainly comprises a short-time high-power pulse generating circuit, a laser signal control circuit and a pulse trigger circuit. The power pulse generating circuit employs a Marx generator principle, and is realized with a high-power capacitance matrix with spark discharge gaps. The laser signal control circuit comprises an induction antenna for receiving an electromagnetic wave signal of the pulse generating circuit, a microcontroller connected with the induction antenna and a control output connected with the microcontroller. The pulse trigger circuit comprises a KM1 relay, a power transistor Q1 and a line output transformer T. According to the utility model, the microcontroller under the influence of strong electromagnetic pulse controls discharging. Generated pulse power is loaded into a transmitting coil, and is transmitted to a receiving coil through an electromagnetic coupling resonance principle in a short period of time, thus the power wireless transmission is realized.

Discharges in Water and Applications to Wasted Water Treatment

Abstract: Recently the electrical discharge in water has been used for the water treatment. In this study, various shape of electrodes were examined to observe and measure the electrical discharge phenomena in water. Both the Marx generator and the pulsed power generator were used to generate the discharge in water. The oscillation on the waveforms of both applied voltage and discharge current was observed using the pulsed power generator whose peak applied voltage was about 80-120 kV and its discharge repetition rate was about one pulse per thirty seconds although it wasn't observed on the waveforms in the practical use of the high voltage generator (peak applied voltage was about 30-40 kV) with high repetition rate of discharge (20-300 pulses per second). Bubbles were introduced into the discharge region of main electrode using the ejector and the generation of hydroxyl radicals (OH) was confirmed by the measurement of emission spectrum of discharge in water and the intensity of OH radicals increased with the ratio of G/L (where, G is gas flow rate and L is water flow rate). The hydrogen peroxide (H2O2) was also measured and this reactor system was applied for the de-color of water.
