![]() Remove the 4/6 aluminium screws holding the face-plate to the camera body, and insert a very sharp blade under the plate, cutting around the complete circumference several times. (Normally the camera will not be continuously exposed for long periods).Įventually, the camera body may be opened and the scintillator replaced (after the 12 month warranty period). The neutron scintillator should last indefinitely unless exposed to strong beams for long periods. The standard video CCD unit can be replaced without opening the camera by using the supplied key to loosen the 3 small screws attaching it to the camera body. Like most electronic components, the camera module should be shielded, in particular from neutron and especially gamma-ray background. Life Expectancy & Replacement of the CCD/scintillatorĪfter 2 years on an ILL instrument, the CCD developed additional white pixels. There are no such taxes on shipping within the EU. With FedEx, UPS etc NeutronOptics must pay ~22% taxes, VAT and customs charges on the total declared value including transport, if it is from outside Europe. If possible use the international registered postal service, rather than FedEx, UPS etc, and declare it as a "Camera Scientifique hors service, pour reparation" with nominal or no commercial value. Before returning the camera for repair, please first confirm the return conditions and email me a copy of the shipping papers. Repairs for accidental and operational damage, and repairs ouside the guarantee period, can also be undertaken for all cameras manufactured within the last 10 years. NeutronOptics cameras are guaranteed for at least one year for the quality of components and workmanship, and under guarantee will be repaired cost free on return to the manufacturer. Do not hesitate to email if you have problems or comments, however trivial. Intermittant electrical problems may be due to a poor fit of the electrical plug to the camera. If however, nothing seems to work, the most likely reason is that you have a bad electrical connection! Check all the cables in one case a user even had a thin plastic film stuck in one of the connections. This is normal for such a highly sensitive CCD (you can apply a software filter to remove them). If you expose with high gain and 10+ seconds exposure, even without a neutron or x-ray beam, you should see a few isolated bright pixels in the image. A solution is to subtract a "dark field" image obtained under the same conditions with the neutron beam off, or use the ImageJ Process/Subtract Background. This is low-level infra-red radiation from the amplifiers at the edge of the CCD.
