News on China's scientific and technological development.

There are ongoing research on EUV for sure, but are they actually using exascale super computers, not just regular computers, in EUV research? Like you said, they had mastered 2 major technology. For the third, have they actually mastered the technology for the power source already? So the only thing holding them back is the construction of the cyclotron with 16 lines in Beijing, not the mastery of the technology?
@henrik bro repost from the Semiconductor thread
@tokenanalyst bro great find, official confirmation of the DUAL BENCH develop by U- Precision, one of the 3 core component for EUVL, the other is optics by CIOMP both had been successfully develop. while waiting for the 3rd which is the light source, China is working on 4 possible solution as urgency dictate the need for an operational EUVL.
1)CIOPM (Changchun Institute of Optics and Mechanics) Dual wavelength laser coaxial output system.
2) CAS (China Academy of Science) Institute of High Energy Physics develop an adjustable Extreme Ultraviolet light source tech? Adjustable?
3)Sichuan University develop a 13.5 light source that can be use on DUVL, EUVL and other high end Lithography body, a LPP?
4)finally the SSMB
IF you read our discussion or follow @WTAN post between him and our esteem member @Skywatcher below:
I think Havok was probably being very conservative when he mentioned that the first SMEE EUVL would be equivalent to the NXE3100.
The resolution of the EUVL is determined mainly by the Source Power of the Light Source.
The CIOMP Tech Demonstrator and the NXE3100 both used a LPP Light Source with source power of 10W.
ASML then produced upgrades to the Light Source
NXE3300 40W-80W
NXE3350 120W-150W
NXE3400 200W
No one knows the current source power of the LPP Light Source being developed by Shanghai Inst of Optics. Its pretty certain to be higher than 10W.
But the DPP Light Source developed by Harbin Inst produces 150W+.
A EUVL that uses the DPP Light Source of 150W+ would mean something falling in between the NXE3350 and NXE3400.
The expected Chinese EUVL had finished its development in 2020 powered by DPP BUT the light sources is inadequate (Cymer used by ASML had a LPP producing 250W and so is Gigaphoton of Japan), so back to the drawing board and now you're looking at a possible 4 candidates. SSMB is the most ideal BUT may take until 2025, I need an expert opinion about CAS adjustable Extreme UltraViolet light source and CIOPM Dual wavelength laser coaxial output system? what are they? and I think Sichuan University product is a LPP. So China is covering all base possible to have it's owned EUVL operational ASAP.
China's airship sets new altitude record of 9,050 meters on Mt. Qomolangma
Updated 15:41, 31-May-2022
China's self-developed floating airship, "Jimu No.1" type III, designed for atmospheric observation, completed its 10th ascent for high-altitude observation on Thursday for data collection at Mount Qomolangma, the world's highest peak on the China-Nepal border.
The ship ascended to an altitude of 9,050 meters on May 21, breaking its own record set on .
"Of all the 10 observations, two reached over 9,000 meters, and six exceeded 8,000 meters of observation height. And this time, we basically completed the observation mission beyond our expectations in six indicators," said Gao Jing, a research fellow with the Institute of Tibetan Plateau Research at the Chinese Academy of Sciences (CAS), who also leads the airship observation team.
Developed by the Aerospace Information Research Institute of the CAS, the floating airship has a volume of 9,060 cubic meters. It is 55 meters long, 19 meters high and weighs 2.63 tonnes.
"In the past, weather balloon and satellites were among the most-used tools for high-altitude observation. We also used models for simulations. Observations on the same point, from ground to high-altitude, never took place before this. We could say that our observation [by using floating airship] has high precision, as we managed to control the speed of the entire elevation of the airship. Or to say, [we've] maintained quite a stable state of all the instruments [attached to the airship]."
As a high-precision observation instrument, the floating airship will provide vital data on the water resources of Qinghai-Tibet Plateau and help tackle the chain effects of water, ecology and human activities under climate change.
With the help of the observations, the research team is able to obtain the precious data on atmospheric changes from ground to high altitude at Mount Qomolangma, which can lay a major scientific basis for the environmental changes on the Qinghai-Tibet Plateau under the influence of westerly wind monsoon.
"For the mission on Asia's water tower, the data is brand new. I think, from my perspective, it is a new starting point for understanding the water circulation and the carbon circulation in the entire water tower of Asia," said Gao.
With the data collected, scientists would be able to build a model to simulate the atmospheric transport process on a global scale.
Pretty surprising how short that list is.
From 4 years ago, expect the list to be even shorter now, with a huge thank you to Trump and US behavior.
You mean this? Construction of Dalian Coherent Light Source, or DCLS, was completed in 2017. Operational acceptance was certified in 2018. "The world's only free-electron laser in the extreme UV spectrum. It is also the brightest laser in that spectrum."
it'd be really interesting to have an update
