Discussion Overview

The discussion revolves around the feasibility of generating extreme ultraviolet (EUV) light (wavelengths less than 150nm) without incurring high costs or requiring extensive equipment. Participants explore various methods and technologies, while also addressing the implications of having no specific requirements for wavelength, intensity, or duration.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant questions the possibility of producing EUV light without significant investment, suggesting that if one has to ask, the answer is likely no.
  • Another participant mentions gas discharge lamps as a potential, albeit limited, method for generating light, noting that they primarily produce longer wavelengths.
  • Concerns are raised about the definitions of EUV and related wavelengths, with participants pointing out that the original query could include soft X-rays, which can be produced using older technology like CRT tubes.
  • There is a discussion about the practical applications of EUV light, with mentions of lithography and micromachining as possible uses.
  • A participant shares links to suppliers that claim to produce light sources in the UV range, suggesting that there may be commercial options available.

Areas of Agreement / Disagreement

Participants express skepticism about the feasibility of generating EUV light without high costs or specific requirements, indicating a lack of consensus on the original question. Multiple viewpoints are presented regarding the definitions and potential methods for generating EUV light.

Contextual Notes

Participants highlight the importance of precise definitions when discussing EUV light, as broader terms may lead to confusion with other types of radiation. There is also mention of safety concerns associated with EUV exposure.

My question is: if you had no requirements for specific wavelength, intensity, duration, etc., are there ways of producing euv light (<150nm) without billions of dollars of equipment and power requirements in the KWs at most. Any Ideas?

No. This is an area of technology where if you have to ask us, the answer is no.
BTW, "no requirements for specific wavelength, intensity, duration"; really?
Also, it's not billions, maybe a million dollars to do something useful with euv.

The closest cheap way that I know of would be a gas discharge lamp, Xe, Ar, Kr, Hg, etc. But you'll mostly get longer wavelengths.

Be more careful with your definitions, please. Right now, it includes soft X-ray too, and all you need for that is an old style CRT tube.

Good point. Also cosmic rays, they're free.
The broader point is that NOBODY that needs EUV will have no specifications.
I'd also warn about skin cancer, burns, and cataracts, but this isn't actually going to happen, so I'm not worried.

Wow, quick responses. Ok, fair points above, and I think I have my answer now anyway.
Just for the sake of completeness, I would be thinking of the range from approx. 125-150nm. Meaning the discharge lamps are unfortunately too long wave.

Can i ask what you mean by "do something useful"?

IDK, maybe ask google? The only euv application that comes to my mind is lithography or maybe micromachining?

Google was my first stop, hence my attempt to tap the big brains.

Appreciate the help all the same. Guess ill keep my fingers crossed for some significant innovation in the area.
