Atomic screen

  1. Jun 4, 2013 #1
    Hi , well this is just a idea that came up when thinking about a certain problem in physics.

    Now it's late and I don't wan to be long but is it possible or has it been done , a device that could for example hold back lighter nuclei and let through heavier ones or vice versa?
    Well imagine a pipe that has some gas or plasma under pressure and at the end a nozzle but the nozzle let's only heavier nuclei through so unless those nuclei have fused or etc they cannot escape the nozzle.

    Somewhat like a sieve for rocks , when you want to separate bigger ones from smaller ones or from sand for building purposes.

    Helium and hydrogen can diffuse through many materials quite easily (at least compared to other nuclei) as they are so small. This is a serious issue if you want to have a good vacuum.

    I doubt that this can be used in any fusion-related way.

    Typically it works the reverse way. The lighter, smaller objects are allowed through while the bigger ones are trapped. I don't see any way to make it work the way you are asking.
