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

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.
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.

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?
