5Experimental Status of the HANBIT Facility显示文摘HANBIT is a magnetic mirror confinement device. Recent physics experiments have been mainly focused on identifying discharge characteristics and on getting stable plasma production and operation modes, by using a 500 kW slot antenna system at a fixed RF frequency of 3.5 MHz and varying discharge conditions such as fueling rate, RF power, and B-field intensity in central cell. Two distinct operation modes are found to be very sensitive to the RF power as well as the ratio of the RF frequency to the ion cyclotron frequency. A MHD interchange mode of m- -1 is clearly observed and the stabilizing mechanism can be explained by the sideband coupling theory.S.J.Yoo M.Kwon J.G.Bak K.Choh I.S.Choi J.H.Choi J.W.Choi A.C.England J.Hong H.S.Jeon H.G.Jhang J.S.Ju M.Jung J.Y.Kim S.S.Kim W.H.Ko K.Y.Kwak M.C.Kyum B.J.Lee D.K.Lee J.H.Lee H.G.Lee S.G.Lee T.Lho H.K.Na B.H.Park M.K.Park D.C.Seo S.H.Seo J.H.Yeom J.S.Yoon K.I.You 2004Plasma Science and Technology2004,6,4:1
6Customized 3D-printed occluders enabling the reproduction of consistent and stable heart failure in swine models显示文摘Reproducibility of clinical output is important when investigating therapeutic efficacy in pre-clinical animal studies.Due to its physiological relevance,a swine myocardial infarction(MI)model has been widely used to evaluate the effectiveness of stem cells or tissue-engineered constructs for ischemic heart diseases.Several methods are used to induce MI in the swine model.However,it is difficult,using these approaches,to obtain a similar level of functional outcomes from a group of animals due to interpersonal variation,leading to increased experimental cost.Hence,in order to minimize human intervention,we developed an approach to use a customized occluder that has dimensional similarities with that of the coronary artery of animals in the case of the swine model.We carried out angiography to measure the diameter of the middle left anterior descending artery of each individual animal to fabricate the customized occluder using a 3D-printing system.The fabricated occluder contained a central hole smaller than that of the targeted middle left anterior descending artery to mimic an atherosclerotic coronary artery that has an approximately 20%blocked condition.Interestingly,the 3D-printed occluder can provide continuous blood flow through the central pore,indicating a high survival rate(88%)of up to 28 days post-operation.This method showed the possibility of creating consistent myocardial infarction induction as compared to the conventional representative closed-chest method(50%survival rate),thus highlighting how our method can have a profound effect on accelerating reliable experiments for developing new therapeutic approaches to ischemic heart diseases.Han B.Kim Seungman Jung Hyukjin Park Doo S.Sim Munki Kim Sanskrita Das Youngkeun Ahn Myung H.Jeong Jinah Jang Young J.Hong 2021Bio-Design and Manufacturing2021,4,4:0
7A study on low emittance injector and undulator for PAL-XFEL显示文摘For the success of PAL-XFEL, two critical systems, namely a low emittance injector and a variable gap out-vacuum undulator, are under development. In order to realize the target emittance of the PAL-XFEL injector we carried out an optimization study of various parameters, such as the laser beam transverse profile, the laser pulse length, the laser phase,and the gun energy. The transverse emittance measured at the Injector Test Facility(ITF) is εx=0.48±0.01 mm mrad.An undulator prototype based on the EU-XFEL design and modified for PAL-XFEL was built and tested. A local-K pole tuning procedure was developed and tested. A significant reduction(90%) of the local-K fluctuation was observed. The requirement of undulator field reproducibility better than 2×10-4and the undulator gap setting accuracy below 1 μm were achieved for the prototype. The optical phase jitter after the pole height tuning at the tuning gap was calculated to be 2.6? rms, which satisfies the requirement of 5.0?.J.Hong J.-H.Han S.J.Park Y.G.Jung D.E.Kim H.-S.Kang J.Pflueger 2015High Power Laser Science and Engineering2015,3,3:0
