    Old article:

    Status update:

    http://www.economist.com/node/21552169

    Basically, the idea is to use various particle physics detectors to actually plot the tracks of cosmic muons, and see if they scatter off of anything inside a cargo. Nuclear materials scatter incoming cosmics in a specific way.

    These are the same types of detectors we invented for use at the LHC 25 years ago.

    People often ask "what's the practical purpose of the research you did" and I respond "practical spinoffs often do not become clear until after the technology has existed for a while." This is a good example.

    I'm still waiting for my Klingon disruptor.

    Probably already in use - or something like it.

    This thread is ridiculous because I don't understand a single word of it. :uglylol: :crazy: :headscratch: :mememe:

    As long as it will protect my superpowers from kryptonite, we're cool.

    I hear there's a shawarma place just down the street....

    If you mean ancient x-ray tech...then yes.

    We worked on 90 GHz passive background radiation sensors during Star Wars days.

    You could read a newspaper held in a parking lot during heavy overcast, at night, from high altitude.

    This frequency is one of a few that are not attenuated by moisture in the atmosphere.

    Work with Josephson Junctions later. Subsequently this device was used by astronomers to map the surface of the planet Jupiter through a telescope.

    Many neat things take time to get to practicle use.

    I'm a physicist, not an engineer. You lost me with the 90 GHz part--where does that come in?

    (goes off to calculate the wavelength and energy of 90 GHz photons to see if he can figure it out)

    Wouldn't we be better off inventing a Flux Capacitor so we could just go back in time once a nuke is detonated and prevent it from being planted in the first place?

    :supergrin:

    I don't think there are enough running DeLoreans left to make that a viable plan

    Will it detect nukes through lead shielding?

    Yes, that's basically the point. Through lead shielding and without requiring radiation.

    (Although technically it detects the nuclear material, not the nuke itself--it's not an x-ray, it won't tell you what the bomb inside the crate looks like. Just if there's material inside with large atomic mass, and approximately where it is.)

    Damn! I forgot to consider the DeLorean factor!

    Natural thermal background radiation is present in the 90 GHz region(there are other band where this is true but the 90 GHz with shorter wavelength, is capable of higher resolution) You can also use commercial glass lenses to focus like an antenna.

    Also at that time, it was difficult to find commercial sources and attachments at higher frequencies. We were not developing the electronics but the application.

    The significance of the 90 GHz is that it is one of a few frequencies that are not attenuated by water molecules in the atomosphere. Therefore very high sensitivity over long distances.

    I just grabbed an article (of many) discussing a use related to my comments.

    It's fascinating technology.

    What happens if we use a Smart Car instead of a DeLorean?

    So, what you are saying, is that having worked closely with nukes, I've had many exotic particles pass through my body?

    Can I get disability for that? :rofl:

    Is that what they are calling it nowadays? We always just called them strippers.

    Because when you go back in time and they see the Smart Car they laugh so hard it makes you mad and want to leave as quickly as possible.
