Hi JonB,

Don't worry this is an original gizmo. Never saw it before anywhere.

Is it some kind of gauge used in some manufacturing process?

--------
"gauge" has 5 different interpretation in my english-slovene dict. so i am not sure about this but i think it is not gauge.

and it is not used in manufactoring process.

Does it use any light or optics?

Are some wires or plugs missing from the unit?

you dont "look" into this,at least that is how i undertand from description.

Are some wires or plugs missing from the unit? i think that is all what is displayed.

Anything to do with laser?

not laser, but to make it is placed between some source and some other thing.

i think it is a hard one(or no one is here) so i will help a little.

i am not 100% sure but i think it is not laser..there is noi mention of laser on that page but something other in form of ray.

collimator:

  • a tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beam

  • a telescope arranged and used to determine errors of collimation, both vertical and horizontal.

  • used for producing a beam of parallel rays

  • used for alignment or for X-ray lithography

    The BNCT interdisciplinary group in the Czech republic decided as a first priority to initiate the glioma clinical trial at the LVR reactor of NRI. The principal aim now is to prepare the Phase I trial, to establish maximum tolerated dose by healthy tissue when irradiating with BSH drug. The activity has been concentrated in this final stage also on improvement of the parameters of the beam. The treatment protocol was prepared and put forward to corresponding authorities for approval?

    Boron Neutron Cancer therapy?

    scott. i think it is incorrect.(as object or project) give me picture to judge, maybe it is the same thing but i think it is not .also i am not asking for what is WHOLE package but jsut this object.

    I guess the 'C' stands for capture..not cancer.

    Shadow cone

    Used to minimize the direct illumination of a neutron detector by placing it between a neutron source and the detector. This method allows for an accurate background determination, i.e., the scattering of neutrons from the floor, ceiling etc. into the neutron detector can be measured and subtracted off from the counts measured in the neutron detector without the Shadow Cone in place.

    particle accelerator for neutron radiography: a beam of particles penetrates the target, and the shadow of the device is captured.

    sometimes used to inspect nuclear reactors?

    FINALLY - i was starting to worry now :) ...after mentioning "neutron" and then "detector" all you had to do was search for "neutron detector". pic in page 2 at google image search.

    scott you win! congratulations!

    url:
    [phy.duke.edu...]

    btw, first i wanted to use Space Star Neutron Detector Array but i was afraid that it is too easy to guess...

    I think this is the correct url, they must be
    updating the website as the picture keeps changing.

    Sweet! Now what happens? I've never won before. Is it like winning the powerball lottery? What's my take after taxes and can I take it in a lump sum? :)
