China has synchrotron in Guangzhou

The article states the SSMB will be constructed in XNA (Hebei). What's Guangzhou got to do with it?

Source for this? The SSMB is a synchrotron (granted, a small one) and in China those typically take 5 years from the start of construction to first operation.

The larger the synchrotron the longer it takes to build.

Yes, that's obvious and I alluded to it in the post. However, the number of years it takes to build isn't a function of circumference. There's going to be some chunk of time that's constant no matter the size of the synchrotron (producing and installing equipment, training personnel, etc.) A 2025 date is really pushing it, even if its Q4 2025 and construction begins immediately.

I think 2027/8 is more reasonable.

Does China have any plan to secure the supply of borate minerals? Currently NATO member Turkey possesses 72% of the world's known boron deposits.

The research team of Professor Peng Lianmao and Researcher Qiu Chenguang from the School of Electronics, Peking University has prepared a 10nm ultra-short channel ballistic two-dimensional indium selenide transistor, which for the first time makes the actual performance of the two-dimensional transistor exceed Intel's commercial 10nm node silicon-based Fin transistor, and The working voltage of the two-dimensional transistor is reduced to 0.5 V, which is also the fastest and lowest power consumption two-dimensional semiconductor transistor in the world so far. The relevant research results are titled "Ballistic two-dimensional InSe transistors" and published online in the journal Nature on March 22, 2023. Doctoral students Jiang Jianfeng and Dr. Xu Lin from the School of Electronics are the co-first authors, Professor Peng Lianmao and researcher Qiu Chenguang are the co-corresponding authors, and the School of Electronics of Peking University is the sole unit of the paper.

SSMB is just light source. The is a lot more than light source in EUV machine，let along EUV photoresist，EUV mask etc.

But Synchrotrons easily produce radiation in all ranges of the EM spectrum, from long to x-rays, no?

yes, synchrotron is tunable. but the reason why people picked EUV over X-ray is due to the X-ray photoresist problem (no material absorbs X-rays well enough) and the X-ray mask problem (X-rays too short to manage with projection optics). Exactly 13.5 nm EUV itself has problems too, but luckily they've been solved generously by others, so China only has to manage a novel light source.

So if china can crack the x-ray mask and x-ray photo resist problems in the future China can just upgrade those newly built EUV infrastructure to X-ray light source infrastructure?
