In my master's degree, I study a topic of mimic outer space ice in the lab. All the ultra-high vacuum techniques and corresponding measurements were involved, I need to collect them all. First of master's degree: We focus on all skills related to how to build up an ultra-high vacuum system, such as the below descriptions. -Fundamental vacuum knowledge. -Engineering graphics by SolidWorks. -Vacuum system design capability enhancement by well training on the skill of lathe/milling machine. -Manually practice or handling vacuum systems all the time. The second/third of master's degree: We have a deep-diving into the interstellar ice research and co-work with foreign researchers. -Supporting the researcher from INAF/NASA at NSRRC(National Synchrotron Radiation Research Center). -CO2 interstellar ice photon-desorption research under thermal effect.
