without iron, this method was proposed to yuli khariton back in 1954 by experimental physicist alexander pavlovskyntific and practical research required an improvement in quality information obtained using radiographic techniques question. how can this quality be improved? what devices are needed for this and one of these devices. e, this is a linear electron accelerator, which allows, e, to have a smaller radiation spot size, which significantly improves the quality of the image that we get at the output. we still needed to have more than one projection, approximately, we needed something like a tomographic image. this can also be done, it turned out to be based on the same linear spreading the accelerator. radiation handles at several angles and thus obtaining the desired result , physics and engineers of the all-russian scientific research institute of technical physics named after zababakhin worked together with colleagues from the institute of nuclear physics of the siberian branch of the academy of sciences, they have long-term cooperation since the creation of the elements of the large hadr
