Modern shipping has fruits and vegetables of various types transported together by container ship; however, the amount of ethylene released and the sensitivity of various produce toward ethylene vary. As such, if products with high ethylene release such as apples are mixed with those with high ethylene sensitivity such as persimmons, the latter will ripen excessively. Non-thermal plasmas (NTP) such as dielectric barrier discharges (DBD) and corona discharges have been investigated as a way to decompose ethylene. Nanosecond (ns) pulsed discharge, a type of NTP, is known to generate O3, treat exhaust gases and decompose VOCs with higher energy efficiency. However, many issues still remain prior to industrial implementation, including increasing energy efficiency for the removal of formic acid (HCOOH), CO, and O3 resulting as byproducts; there are also decomposition limitations in areas of low ethylene concentration. Overcoming these limitations is the purpose of this work. The output voltage of our ns pulse generator was 30 kV–50 kV in amplitude, 10 pulse/s–100 pulse/s in repetition rate, and 5 ns in pulse width. 100 ppm ethylene diluted with dried air was employed as gas simulating that of a transportation container. The gas mixture was fed into the coaxial cylinder type reactor for evaluation of decomposition efficiency. Ethylene concentration decreased to less than 0.1 ppm after ns pulsed discharge treatment at 30 J/L in input energy density. O3, CO, NO, HCOOH, HNO3 were generated as byproducts; byproduct concentrations were measured.","PeriodicalId":247019,"journal":{"name":"2017 IEEE 21st International Conference on Pulsed Power (PPC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133151528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are same works published last time in which considered this problem, but it wasn't many. We mention the works [1] and [2], where attempts have been made to obtain fusion processes in PF devices. As shoved Niculin [3], increasing of discharge current of PF more than 2 MA haven't been to proportionality increase of plasma density. There is known, that in coaxial guns appear a Hall Effect, which decreased a plasma velocity [4]. If we exclude this phenomenon from plasma, there is possible to increase the energy of plasma particles. But the ways of plasma description, based on average energy 3kT/2 is not suitable for PF devices, as well as Lawson criteria. For these devices the target theory is more applicable. So, we are apology, that not only power, but geometry of experiment play important role. On this way, we have made experiments on basic of pulsed plasma accelerator CPA-30 with short and long electrodes. The experiments showed a significant dependence of the flux focusing parameters on the electrode geometry. Analysis of experiments and calculations show, that the efficiency of plasma compression became much higher with a short electrode. However, as the length of the electrode decreases, no increase in the plasma temperature is observed. The reason for this is the too long discharge time, so the accelerated particles in the plasma can be thermal. To start the synthesis and emission of X-rays from the focus region, calculations show that discharge times on the order of picoseconds are necessary.","PeriodicalId":247019,"journal":{"name":"2017 IEEE 21st International Conference on Pulsed Power (PPC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125122320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typical pulsed power applications like plasma initiation and high-energy LASER require operating voltages in the order of several kilovolts. The development of a multi-kilovolt SiC MOSFET for fast switching pulsed power application would require detailed analysis of the device switching characteristics. Since the switching speed of a MOSFET is primarily dependent on the inter-electrode capacitances, it becomes critical to have a comprehensive understanding of the device capacitance and its effect on the gate driver requirements for narrow-pulse switching. In this research, 2D model of a 10 kV 4H-SiC MOSFET was developed using Silvaco ATLAS TCAD software and simulated for its steady state, AC, and transient characteristics. The device cell was designed for an active area of 5 μm2 and 100 A/cm2 drain current density. The capacitance-voltage and gate charge curve for the SiC MOSFET were obtained via AC and transient simulation respectively. This data was used to estimate the gate drive requirements for the device under fast switching conditions.","PeriodicalId":247019,"journal":{"name":"2017 IEEE 21st International Conference on Pulsed Power (PPC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128884643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case localised surface fields can be excited around the perturbations if the structure is radiated by an external source (for example an electron beam). Experiments were conducted using a velvet cathode electron gun with the electron accelerating voltage produced by a cable Blumlein generator. “Additive Manufacturing” or “3D printing” was used to construct a silver 2D PSL quickly, efficiently and relatively inexpensively. The electron beam formed within an 18 mm bore 1.8 T solenoid was transported through the 7.2 mm inner diameter silver 2D PSL beam-wave interaction region. An 80 kV, 100 A electron beam with an outer diameter of 4 mm and inner diameter of 2mm which was approximately 1.8 mm away from the inner surface of the 2D PSL corrugation was measured.
