Dispersion equation of the TWT is discussed and the behavior of propagation constants of the helix TWT structure is expressed when beam-wave interaction occurs. All possible waves or modes which play important role in the amplification process are considered. The effects of loss due to interaction circuit, space charge effects and beam velocity variations are taken into account when solution of the dispersion equation and TWT gain characteristics are carried out. Fundamental aspects of the TWT small signal gain analysis with Pierce parameters such as b (velocity parameter), QC (space charge parameter), d (cold tube circuit loss) are examined. Some significant figures are obtained to express the behavior of the gain with respect to Pierce parameters. It is noted that Pierce small signal theory gives important information to investigate the gain characterization of the TWT considering natural effects of beam velocity, circuit loss and beam-wave interaction.","PeriodicalId":104929,"journal":{"name":"2017 IV International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128086542","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 electric field strength that is radiated from an electronic device is measured on RE test. The measured values are can be differential depending on some variables. Measurement distance between receiving antenna and product to be tested must be constant during RE tests of ILC. The Equipment under Test (EUTs) height also has to be same. The antenna can be constant or can be movable. This situation affects the measurements majorly. The ILCs can be success or failed because of the varying parameters. EN 17025 “General requirements for the competence of testing and calibration laboratories” requires that test and calibration laboratories continuously shall prove proficiency in performing measurements as part of assuring the quality of their results and monitor the validity of performed tests. Comparison tests between test setup in different laboratories are important from the point of test accuracy, validity, repeatability. In the same way, these ILCs are the requirement of laboratory accreditation. Accredited test laboratories shall participate to ILCs according to the requirements of the EN 17043 “Conformity assessment — General requirements for proficiency testing standard”. ILCs should be performed more carefully and more detailed for primary critical tests that have also complex setup such as RE test. In this study, the effect of the measurement height on the ILCs for RE test was examined. The results also were evaluated based on the |En| scores.","PeriodicalId":104929,"journal":{"name":"2017 IV International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133037376","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}

Simulations are performed in MAGIC Tool Suite which uses FDTD-PIC algorithm to solve particle beam and field interactions. During the design procedure, AK Gap is changed from 5 mm to 12 mm and the scaling law is verified by simulation results. 9 mm AK gap values are selected as the most suitable one when output power and frequency of radiated field are taken into consideration. Further investigations are made by using 9 mm AK value in simulation environment. Formation of the virtual cathode is confirmed by Pz vs. z phase space diagram. The mean of applied input voltage value and input power value are found as 87.76 kV and 246 MW, respectively. The peak power and the average power for the generated microwave at the output are also 6.3 MW and 1.8 MW. Thus, power conversion efficiency for both peak and average output power are obtained as 2.56% and 0.73%, respectively. Frequency of the radial and longitudinal components of the produced electric field at the output is 2.92 GHz. Waveguide mode at 2.92 GHz is inferred from radial field distributions of fields and the propagating mode is found as TM01 at 2.92 GHz, which verifies our prediction.","PeriodicalId":104929,"journal":{"name":"2017 IV International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122004189","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}

Simsek","doi":"10.1109/EMCT.2017.8090359","DOIUrl":"https://doi.org/10.1109/EMCT.2017.8090359","url":null,"abstract":"The purpose of this investigation is to present a Ku-Band Helix Traveling Wave Tube Amplifier (TWTA) design and simulation procedure with considering initial design assumptions. The design process which consists of four critical steps is stated. Firstly, required input parameters such as dc beam current (Io), dc beam voltage (Vo) and frequency band of operation are chosen. Determination of the design objectives such as gain and output power constitutes the second stage of the design procedure. For this purpose, overall gain in considered frequency range is specified as over 20 dB. The output power is aimed to 100 W. To obtain design objectives mentioned in the second step, it is necessary to have optimum helix slow wave structure (SWS) design parameters such as helix pitch, radius and pitch angle. Therefore, the optimized design parameters of the SWS are determined by using Eigen Mode Solver (EMS) (cold (beam absent) analysis) of Computer Simulation Technology (CST) Microwave Studio (MWS) for acquiring the beam-wave synchronization. Particle in Cell (PIC) simulation (hot (beam present) analysis) is carried out by assuming the uniform electron beam flow. The length of the interaction structure of the designed TWT is nearly 110 mm and all design objectives are nearly achieved as it is expected. Many crucial figures related to gain, power and beam wave interaction are depicted with detailed explanations. Furthermore, the design limitations of this proposed design due to assumptions are also clarified.","PeriodicalId":104929,"journal":{"name":"2017 IV International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124549261","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}
