探索內太空的水下無人載具

黃盛煒 博士(臺灣大學 船舶及海洋技術研究中心)

<專題討論>2021/12/2(四)14:10綜合大樓2樓48218教室演講

海洋雖然占了地球表面70%面積,大多數的人對於深海猶如內太空般的一無所知,甚至以為海面下無法透光的地區是沒有任何生物可以生存,20世紀以來即使科技進步,隨著先進研究船、浮標、水下無人載具及人造衛星等紛紛投入海洋研究,已漸漸揭開深海神秘的面紗,至今還是無法窺盡海洋神秘的全貌。尤其是海洋研究船與相關技術和設備的建立是海洋生物學家探索深海重要的利器之一,今日的海洋研究船擁有最新的航儀裝備、探測儀器與設備,能探測先前因技術不足所無力抵達的地方,將對海洋的探索範圍大幅加深且加廣。自1960年起,水下無人載具開始發展並被廣泛運用在各種水下探測任務和生物相關研究。水下無人載具的操作者並不需要下水,可以在船上或陸地上遠端遙控機器或是預先設定指令,即可從事水下探測、標本蒐集等工作,水下無人載具不僅延長了在水下工作的時間、同時也提升了人員安全。本次演講希望透過分享近期對於水下無人載具研發成果,一同了解內太空探測技術的發展。

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.

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.
