| 1 | Studies of laser-plasma interaction physics with low-density targets for direct-drive inertial confinement fusion on the Shenguang III prototype显示文摘The physics of laser-plasma interaction is studied on the Shenguang III prototype laser facility under conditions relevant to inertial confinement fusion designs.A sub-millimeter-size underdense hot plasma is created by ionization of a low-density plastic foam by four high-energy(3.2 kJ)laser beams.An interaction beam is fired with a delay permitting evaluation of the excitation of parametric instabilities at different stages of plasma evolution.Multiple diagnostics are used for plasma characterization,scattered radiation,and accelerated electrons.The experimental results are analyzed with radiation hydrodynamic simulations that take account of foam ionization and homogenization.The measured level of stimulated Raman scattering is almost one order of magnitude larger than that measured in experiments with gasbags and hohlraums on the same installation,possibly because of a greater plasma density.Notable amplification is achieved in high-intensity speckles,indicating the importance of implementing laser temporal smoothing techniques with a large bandwidth for controlling laser propagation and absorption. | V.T.Tikhonchuk T.Gong N.Jourdain O.Renner F.P.Condamine K.Q.Pan W.Nazarov L.Hudec J.Limpouch R.Liska M.Krus F.Wang D.Yang S.W.Li Z.C.Li Z.Y.Guan Y.G.Liu T.Xu X.S.Peng X.M.Liu Y.L.Li J.Li T.M.Song J.M.Yang S.E.Jiang B.H.Zhang W.Y.Huo G.Ren Y.H.Chen W.Zheng Y.K.Ding K.Lan S.Weber | 2021 | Matter and Radiation at Extremes2021，6，2： | 2 |
| 2 | Design,installation and commissioning of the ELI-Beamlines high-power,high-repetition rate HAPLS laser beam transport system to P3显示文摘The design and the early commissioning of the ELI-Beamlines laser facility’s 30 J,30 fs,10 Hz HAPLS(High-repetitionrate Advanced Petawatt Laser System)beam transport(BT)system to the P3 target chamber are described in detail.It is the world’s first and with 54 m length,the longest distance high average power petawatt(PW)BT system ever built.It connects the HAPLS pulse compressor via the injector periscope with the 4.5 m diameter P3 target chamber of the plasma physics group in hall E3.It is the largest target chamber of the facility and was connected first to the BT system.The major engineering challenges are the required high vibration stability mirror support structures,the high pointing stability optomechanics as well as the required levels for chemical and particle cleanliness of the vacuum vessels to preserve the high laser damage threshold of the dielectrically coated high-power mirrors.A first commissioning experiment at low pulse energy shows the full functionality of the BT system to P3 and the novel experimental infrastructure. | S.Borneis T.Laštovickaˇ M.Sokol T.-M.Jeong F.Condamine O.Renner V.Tikhonchuk H.Bohlin A.Fajstavr J.-C.Hernandez N.Jourdain D.Kumar D.Modranskýˇ A.Pokorný A.Wolf S.Zhai G.Korn S.Weber | 2021 | High Power Laser Science and Engineering2021，9，2： | 0 |
| 3 | The L4n laser beamline of the P3-installation:Towards high-repetition rate high-energy density physics at ELI-Beamlines显示文摘The P3 installation of ELI-Beamlines is conceived as an experimental platform for multiple high-repetition-rate laser beams spanning time scales from femtosecond via picosecond to nanosecond.The upcoming L4n laser beamline will provide shaped nanosecond pulses of up to 1.9 kJ at a maximum repetition rate of 1 shot/min.This beamline will provide unique possibilities for high-pressure,high-energy-density physics,warm dense matter,and laser–plasma interaction experiments.Owing to the high repetition rate,it will become possible to obtain considerable improvements in data statistics,in particular,for equation-of-state data sets.The nanosecond beam will be coupled with short sub-picosecond pulses,providing high-resolution diagnostic tools by either irradiating a backlighter target or driving a betatron setup to generate energetic electrons and hard X-rays. | N.Jourdain U.Chaulagain M.Havlik D.Kramer D.Kumar V.T.Tikhonchuk G.Korn S.Weber | 2021 | Matter and Radiation at Extremes2021，6，1： | 0 |
