Into ionising particles and X-rays, which are then converted into light using an X-ray scintillator (usually ZnS).Ī neutron Polaroid film camera was used with a scintillator from the beginning of ILL in the early 1970's, and even earlier Just X-ray cameras with a component (usually LiF) to convert neutrons The even older photographic techniques used from the discovery of X-rays. Neutron cameras are almost as old as neutron diffraction itself, and are simply a variation of A wide choice of third party software is available for free, as well as an SDK.Ordinary 12V power supplies are used, together with standard USB-2 cables withĪmplified 10m extensions up to 30m total.If the CCD unit was mounted on a motorised rail, it would have to be inside the box,Īnd the camera would be much more complicated, requiring water cooling.Of the camera box, can be easily shielded, and use simple air cooling. More importantly, fixed geometry means that the CCD unit can fixed to the exterior.This fixed geometry requires no translation components that can fail or malfunction.The scintillator front end to change the optical path length. We use fixed geometry, with a variable Field-of-View obtained by simply exchanging.Neutron scintillators, front-surfaced mirrors and lenses are identical to those used in.We use high volume commercial CCD units, which are inexpensive to repair and replace.The technical advantages of our cameras include: NeutronOptics cameras are competitive with the best imaging cameras found in big laboratories, but are less expensive because as a small company we have lower overheads and less administration. Eventually it might be modified in-house to serve a particular need, but why not start with an off-the-shelf product that is already used by many others ? Frankly it's faster and cheaper to simply buy such basic equipment rather than re-invent it. Although the principles of neutron imaging are simple, there are many details that can only be learned by experience. But even the largest laboratories find it convenient to buy such equipment. It is of course possible for a big laboratory to make their own neutron cameras.
