するようにした点にある。The feature of the present invention is that the separated element collection plate has a structure in which thin plates are laminated, and the collection surface is renewed by sequentially removing the plates each time a certain amount of separated elements adheres to the surface of the outermost plate. That's what I did.
以下、本発明の一実施例を第１図および第２図により説

捕集プレート７上に固体状に捕集される。In Fig. 1, photons that have been adjusted to the wavelength necessary for selective ionization of the isotope of interest in a laser system 1 are introduced into the separator through a transparent window 3 provided in a separator 2. The isotope vapor stream 5 generated from the isotope evaporator 4 located at the isotope evaporator 4 is irradiated. The isotope of interest ionized by the irradiation is electromagnetically separated from the vapor flow, neutralized on the isotope of interest collection plate 6, and collected in solid form. On the other hand, the non-target isotope remains neutral and is collected in solid form on the non-target isotope collection plate 7.
第２図において、着目同位元素捕集プレートは対向する
正負の電極プレート６ａ、６ｂから成る。In FIG. 2, the isotope collection plate of interest consists of opposing positive and negative electrode plates 6a and 6b.

６ｂおよび７は各々支持部材１ｏによって支持される。The positive electrode plate 6a has a structure in which thin plates are stacked, and the solid 8 of the isotope of interest is attached to the outermost layer, that is, the surface of the plate closest to the isotope vapor flow 5. The non-target isotope collection plate 7 similarly has a structure in which thin plates are stacked, and the solid 9 of the non-target isotope adheres to the surface of the bottom plate. plate 6a,
6b and 7 are each supported by a support member 1o.

る。Recovery of the isotope is performed by withdrawing the plate each time a certain amount of solid isotope is deposited on the plate. This work can be carried out without stopping the operation of the separator, and the intermediate elements are sequentially deposited on the surface of the next layer of plates, so they can be smoothly recovered without reducing the operation rate of the separation plant. is possible. Continuous collection is possible by installing new plates at appropriate intervals to replace the removed plates.

運転に支障がないようにする。The removal of plates from the separator and the loading of the plates into the separator are carried out in FIG. 1 by plate extraction and installation devices 11a and llb. This device is a gate valve 12
It is connected to the separator 2 via a and 12b, and when removing and installing the plate, the vacuum exhaust device 13 is used to make the inside of the device as vacuum equivalent to the inside of the separator, and then the gate valve is opened. By implementing this, we will ensure that there is no problem with the operation of the separator.

A new replacement plate is installed in the reverse order. The isotope that has been collected and adhered to the plate is removed from the plate by physical or chemical treatment. The recycled boards can be reused as temporary replacements if necessary.
