| 1 | Development of a 750-mm-long stripline kicker for HEPS显示文摘Purpose The superfast kickers are required for the HEPS storage ring on-axis injection system due to its very small dynamic aperture.A 750-mm-long stripline pair type of kicker prototype was researched and developed to demonstrate achieved performance of bandwidth,impedance,kicker strength,field uniformity and beam power loss.Methods The cross sections of the kicker main body and the end of taper part are optimized for a good impedance matching and field uniformity.3D simulation further optimizes the taper part to minimize the beam power loss and maintain a lower reflection.The high-voltage feedthrough is also designed and optimized by 3D CST.RF and high-voltage measurements are taken to verify the design of kicker assembly.Results The testing transmission odd-mode impedance is 50±0.5Ω,the even-mode impedance is 60±0.5Ω,and return loss is less than−13 dB.The peak voltage and the rise time of pulse width inserting kicker assembly just decrease 3%of 20 kV and slow down 80 ps,respectively.Conclusions RF testing results agree well with the simulation ones,which meet the design specification.The kicker assembly works well at±20 kV pulse. | H.Shi J.H.Chen L.Wang N.Wang L.H.Huo G.W.Wang P.Liu X.L.Shi | 2018 | Radiation Detection Technology and Methods2018，2，2： | 1 |
| 2 | Study on the Synthesis and Adsorption Properties of KH-560 Modified PalygorskiteSupported β-Cyclodextrin显示文摘1 Results Palygorskite (PGS) is a chain-layer magnesium-aluminum silicate mineral. Because of its developed interior channels and large specific surface area, and thus considerable adsorption capacity, it has been studied for the application as one of environmental mineral adsorbents[1-3]. Cyclodextrins (CD) possess a hydrophilic exterior and a hydrophobic interior into which a variety of hydrophobic organic molecules maybe introduced. The CD molecule not only affects a hydrophilic cavity on the nanomet... | D.M.ZHU L.YAN X.L.SHI Y.CHANG | 2007 | 复旦学报(自然科学版)2007，46，5： | 0 |
| 3 | Preparation and Catalysis of Aminomethylated Polystyrene Supported Unsymmetrical Schiff-Base Metal Complexes for the Oxidation of Cyclohexene显示文摘1 Results The dominant position of molecular oxygen as the oxidant for bulk chemical oxyfunctionalizations is due to the fact that it is the only economically and environmentally friendly feasible oxidant for large scale processing.But molecular oxygen is not better oxidant than others,such as PhIO,NaOCl,H2O2,alkyl hydroperoxides,percarboxylic acids,magnesium monoperoxyphthalate.So we have to select high reactivity and general utility catalyst.The oxidation of hydrocarbons catalyzed by transition metal ... | X.L.Shi Y.Chang F.Zha Y.G.Wang | 2007 | 复旦学报(自然科学版)2007，46，5： | 0 |
