Description

II

Изобретение oi;ftQCHTCH к ускорительной технике, в частности к ускорйтел м электронов с выводом пучка ускоренных электронов в атмосферу, и может быть использовано преимуще .ственно в радиационной технологии.The invention oi; ftQCHTCH to accelerator technology, in particular to electron accelerators with the output of a beam of accelerated electrons to the atmosphere, and can be used mainly in radiation technology.

Все известные выпускные окна ускорителей электронов дл  радиационной технологии выполн ютс  в виде металлической фольги, вакуумно-Плотн установленной на вакуумной камере развертки пучка 1 .All known electron accelerator outlet windows for radiation technology are made in the form of metal foil, vacuum-tightly mounted on the vacuum chamber of the beam sweep 1.

Однако увеличение ширины вьшускного окна, несмотр  на обеспечение равномерности распределени  пучка,приводит к ужесточенмо условий работы фольги как по тепловому режиму,так и по механической прочности, т.к. удлин етс  путь дл  теплопередачи на фланец и увеличиваетс  механическа  нагрузка от атмосферного давлени . Дл  устранени  этих трудностей фольга снабжаетс  опорной решеткой.However, increasing the width of the opening window, despite ensuring uniform distribution of the beam, leads to stricter conditions for the foil to work both in thermal conditions and in mechanical strength, since the path to heat transfer to the flange is lengthened and the mechanical load from atmospheric pressure increases. To eliminate these difficulties, the foil is provided with a support grid.

Известно устройство выпускного окна, содержащее фольгу, снабженную опорной решеткой в виде опорных элементов, скрепленных с рамкой, и устройство охлаждени  в виде водо-охлаждающих полостей рамки 2.A device for an exhaust port is known comprising a foil provided with a support grid in the form of supporting elements fastened to the frame, and a cooling device in the form of water-cooling cavities of the frame 2.

К недостаткам известных устройств следует отнести то, что даже при оптимальном выборе материала и геометрии опорной решетки- и фольги, перепад температур по опорным элементам составл ет 50-70°С,а температура фольги в наиболее удаленных от опорньк элементов точках при этом достигает, 300-400°С, что ведет, как известно, к.существенному снижению ее механической прочности, а отсюда к малому сроку службы вьтускного окна и увеличеннво простоев радиационной установки дл  смены фольги.The disadvantages of the known devices include the fact that even with the optimal choice of material and geometry of the support grid and foil, the temperature difference over the support elements is 50-70 ° C, and the temperature of the foil at the points most distant from the reference elements reaches 300 -400 ° C, which leads, as is well known, to a significant decrease in its mechanical strength, and from here to the short service life of the open window and the increased downtime of the radiation installation for changing foils.
