In the application the purity of the ion beam is very important, however, the purity of conventional PIB is very poor. To improve the purity a new type of PIB accelerator named \"bipolar pulse accelerator (BPA)\" is proposed. The accelerator consists of two acceleration gaps (first gap and post acceleration gap) and a drift tube placed between the gaps. High power bipolar pulse is applied to the drift tube to accelerate ions. In the accelerator intended ions are selectively accelerated and the purity of the ion beam is enhanced. As the first step of the development of the accelerator, magnetically insulated acceleration gap is developed. The gap has an ion source of coaxial gas puff plasma gun on the grounded anode and a negative pulse is applied to the cathode to accelerate ions. By using the plasma gun, ion source plasma (nitrogen plasma) of current density around 100 A/cm/sup 2/ is produced, which is injected to the anode. After the plasma injection, negative pulse of voltage 220 kV, duration 60 ns is applied to the cathode. In the paper, preliminary results of the experiment are described including the waveforms of the system and shadowgraph measurement. From the results principle of the acceleration of ion beam in the BPA is confirmed.","PeriodicalId":339166,"journal":{"name":"Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop.","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117152761","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}

The large magnet window size, large deflecting angle, low beam impedance termination and fast deflecting field rise time demand a very strong pulsed power source to drive the SNS extraction fast kicker magnet. This system consists of fourteen high voltage modulators and fourteen lumped kicker magnet sections. All modulators will be located in a service building outside the beam tunnel, which is a revised design requirement adopted in the mid 2000. The high current pulses generated by the high power modulators will be delivered through high voltage pulsed transmission cables to each kicker magnet sections. The designed output capacity of this system is in multiple GVA. Its first article modulator has been constructed and is being tested. In this paper, we present the system overview, project status and the advantages of this new conceptual design.","PeriodicalId":339166,"journal":{"name":"Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop.","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121957805","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}

For the preliminary pulse compression, the magnetic pulse compression system was employed. The saturable inductors and transformers transferred the stored electrical energy from the primary storage capacitor to the SOS compressing the pulse. For the final stage of the generator, the SOS was used. By tuning the current fed to the SOS, the amplitude and pulse duration of the generated voltage at the 300-/spl Omega/ resistive load were 150 kV and 60 ns, respectively. Also, general-purpose fast-recovery diodes (FRD) were tested from the viewpoint of the potential candidate as the SOS. The properties of two diodes, of which the reverse recovery time is 100 ns, were tested and found to be enough good as an opening switch. Combining WC and SOS pulse compression scheme, pulsed voltage of 50 kV in amplitude and 20 ns in FWHM is obtained from the relatively low charging voltage of 1.4 kV, which can be repetitively ignited by a semiconductor closing switch.","PeriodicalId":339166,"journal":{"name":"Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop.","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128931514","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}
