謝伯宗 博士兼任執行長(成功大學核心設施中心)

<專題討論>2021/5/6(四)14:10綜合大樓2樓48218教室演講

Core Facility Center (CFC) is one of the university research centers of National Cheng Kung University (NCKU). To support the leading-edge researches, CFC setup a platform with high-end process and inspection tools, and the advanced analytical instruments. Through the public and professional platform, CFC provides its service through either OEM or self-operation modes, all under the E-management booking system. Moreover, through the services provided to both the academic and the industry, CFC plays a platform role for Industry-Academics collaboration with the backup of top-ranked researches in NCKU.

This talk will cover the process and analytical techniques of thin film, which is applied on semiconductor, optoelectronics, material science, bioengineering, and so on. CFC can provide complete thin film deposition and patterning process, and also the precise analyzing techniques for the thin film layer. The mechanism of various thin film deposition process, such as sputtering, evaporation, and ALD will be discussed to help understanding the surface growth engineering. Through the analytical instruments to understand the physical, chemical, structural, mechanical, and optical characteristics of the deposited thin film layers.

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)

<專題討論>2021/4/29(四)14:10綜合大樓2樓48218教室演講

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.

Plasma Related Research on Modeling and Experiments at APPL- an Overview

吳宗信 特聘教授(陽明交通大學機械工程學系)

<專題討論>2021/3/18(四)14:10綜合大樓2樓48218教室演講

摘要:

In this talk, I will present the past and current research in low-temperature plasma physics and its application. In the simulation part, we have been focusing on developing many state-of-the-art parallel computing codes for modeling low-temperature plasma physics and chemistry using unstructured finite-volume method including Navier-Stokes equation solver, fluid model, particle-in-cell (PIC) method and hybrid fluid-particle method. In the experimental part, we have been focusing on atmospheric-pressure plasma and its applications, which include atmospheric-pressure plasma jet (APPJ), plasma activated water (PAW) and plasma activated microbubbles (PAMBs).

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)

<專題討論>2020/12/10(四)14:10綜合大樓2樓48218教室演講

摘要:

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.
