Large scale kinetic simulations on commodity hardware     

Dr. Frank S. Tsung(Department of Physics & Astronomy, UCLA) 


The NVIDIA Tesla V100 GPU, with a peak speed of 28 TFLOPS, would have ranked #2 supercomputer in the world 20 years ago.  With this kind of computing power on our desktops, it is now possible to perform world-class scientific simulations using commodity hardwares.  The UCLA Particle-in-Cell Simulation Group, founded by Professor John Dawson 50 years ago in the 1970’s, has been the leader in the development of particle-in-cell simulation tools on some of the fastest supercomputers in the world.  However, these codes can also be run very efficiently on commodity hardwares such as a single NVIDIA GPU or the Apple M1 processor.  In my talk, I will show some examples of very large simulations performed on some of the largest supercomputers in the world.  In addition, I will show that with a modest budget (1,000,000 NTD, or 30,000 USD), it is possible to build a small cluster that is capable of some producing very high quality, high impact simulations in many areas of plasma physics, including laser fusion, particle acceleration, and space plasma physics.

Ultrafast plasma dynamics in a short-pulse laser ionized gas   

黃振崗 博士(中央研究院 原子與分子科學研究所) 


Since the advent of high-power pulsed lasers, significant amount of attention has been drawn to a laser-induced plasma due to its numerous applications in plasma-based accelerators, radiation generation, and controlled fusion. Characteristics of the plasma ionized from a gas are strongly affected by the ionizing laser pulse and the ionized medium. In most cases, plasma electron distribution is inhomogeneous and anisotropic after ionization. Such a plasma is highly unstable and susceptible to various plasma instabilities. These instabilities, including both electrostatic (two-stream) instability and electromagnetic (filamentation and Weibel) instabilities, rapidly trigger the growth of the density fluctuation, electric and magnetic field [1]. By properly controlling the parameters of the ionizing laser, we may produce a plasma with a certain non-Maxwellian and/or anisotropic distribution function that is suitable for studying kinetic plasma instabilities [2, 3]. A particular interest is on the Weibel instability for its role in plasma astrophysics as a mechanism of self-generated magnetic field [4]. The intricate dynamics of an optical-field ionized plasma are comprehensively studied in theoretical calculations and particle-in-cell simulations. Experimental verification has been done in a series of pump-probe experiments, where the unstable density waves were inferred by short-pulse Thomson scattering measurement [3] and the self-generated magnetic field was measured by electron beam radiography [5].

Relativistic ion acceleration with intense laser pulses    

Prof. Yasuhiro Kuramitsu(Department of Electrical Engineering, Osaka University, Japan) 


We conducted laser ion acceleration experiments using large-area suspended graphene (LSG) as the target. Graphene is the thinnest and strongest 2D material but possesses extremely high thermal and electrical conductivities and extremely low optical reflectivity. We are able to control the LSG thickness as one of the experiment parameter by transferring graphene layer by layer. Based on the LSG technique, we conducted a series of experiments on the laser driven ion acceleration with a diverse parameters of laser such as energies from a few J to kJ, pulse durations from fs to ps, intensities from sub-relativistic to relativistic. 

In this talk, we report our experimental results on energetic ion acceleration with LSG and introduce some novel applications on laboratory astrophysics and nuclear physics.

Bi-directional anode long-acting plasma chemical vapor deposition method applied to contact lenses     

林文賓 博士(亨泰光學股份有限公司 )


Rigid gas permeable (RGP) contact lenses are composed mainly by Silicone methacrylate (SMA) or Fluorosilicone acrylates (FSA) with Polymethyl methacrylate (PMMA). In addition, RGP contact lens can effectively correct different type of ametropia. The surface of RGP contact lens is generally hydrophobic therefore after blinking the eye the tear cannot complete spread evenly over the lens surface and it will result in some discomfort for the eye. The surface of RGP contact lens is generally hydrophobic therefore after blinking the eye the tear cannot complete spread evenly over the lens surface and it will result in some discomfort for the eye. In addition, a clean and well-wetting lens surface is beneficial in managing 3- and 9-o’clock staining. The deposition lipids on RGP contact lenses can be due to the equilibrium of surface hydrophobicity and hydrophilicity of materials.  

In this study RGP contact lenses were modified by Plasma Enhanced Chemical Vapor Deposition (PECVD )  of N-vinyl-2- pyrrolidone (NVP)/poly(ethylene glycol methyl ether methacrylate) (PEGMA) to promote hydrophilicity and the resistance to protein and bacteria. FTIR analyses confirmed the success of coating of NVP and PEGMA on the surface of RGP contact lens. Moreover, the cytotoxicity and cell viability of the NVP/PEGMA coating RGP contact lenses were evaluated by cultivation of L929 fibroblasts and through lactic dehydrogenase (LDH) assays. The protein adsorption on RGP contact lens was investigated by bicinchoninic acid assay using bovine serum albumin (BSA) and lysozyme as model proteins. And the antibacterial potency of the RGP contact lens was assessed using environmental bacterial strains of Staphylococcus Aureus (ATCC 6538).

An Overview of the Interactions, Dynamics, and Energetics in the Atmosphere (IDEA) Research 

黃泰瑩 教授(美國賓州州立大學 物理系)


An overview of our research projects by the Interaction, Dynamics, and Energetics in the Atmosphere (IDEA) team will be presented with the latest results and future projects.  As we know, gravity waves are ubiquitous and play an important role in the energy and dynamics in the atmosphere, especially in the Mesosphere and Lower Thermosphere (MLT) region.  Their interactions with airglow presents a unique opportunity to probe this region remotely.   The projects aim to study gravity wave-airglow interactions, dynamics, and energetics in the atmosphere with a coordinated effort using a numerical approach, ground-based and spaceborne observations.  We have used OHCD and MACD chemistry dynamics models to investigate airglow variations and heating rates induced by gravity waves.  Using airglow and temperature observations from Andes Lidar Observatory, atomic oxygen from SABER, and numerical modeling, we found that the O1S greenline intensity enhancement accompanied by an OH intensity weakening can be explained by a long-period wave with the wave characteristics of a semi-diurnal tide.  We use modeling with observations to find the branching ratios of the three-body recombination for O1S and O2 airglow emissions.  Finding trends by the influences of solar cycle variation, geomagnetic activity, and CO2 increase is conducted by numerical simulations and airglow observations. Exploring metal layers and expanding the work to include the F region among other projects will be discussed.

Development of high-repetition-rate laser wakefield electron acceleration driven by few-TW or sub-TW laser pulses

林明緯 副教授(清華大學核子工程與科學研究所)



 Raising the repetition rate of ultrafast laser pulses that drive the laser wakefield acceleration (LWFA) can straightforwardly increase the average current of accelerated electrons and subsequently generate a high radiation flux desired in advanced X-ray radiography. Instead of using multi-TW laser pulses, the bottleneck of current ultrafast laser technology capable of producing pulses with an energy < 200 mJ at kHz-level frequencies motivates the development of LWFA methods that can be conducted with a moderate laser peak power approaching 1 TW. With the use of thin, high-density gas targets, principles of realizing the LWFA driven by pulses with a few-TW or even a sub-TW peak power will be introduced, including a comprehensive review to the recent simulations and experimental results in this field. Progress about the development of a diode-pumped, ytterbium-based ultrafast laser system expected to drive the sub-TW LWFA will be reported next. Moreover, results of LWFA experiments, when 800-nm pulses of a few-TW peak power are directed into sub-mm nitrogen gas jets and gas cells will be presented. This scheme exhibits a high potential for generating electrons with tens of MeV energies under a satisfactory reproducibility, which is the prerequisite for developing LWFA into a useful source in future radiation applications.
