An apparatus for the rapid thermal extraction of Re radioisotopes from an irradiated tungsten target has been developed. Its operation was tested using a tungsten target pre-irradiated with deuterons on the U-150 cyclotron of the Kurchatov Institute. A description of the design of the apparatus and the principle of its operation are given. It has been shown that in one two-stage calcination–sublimation cycle, at least 89% of the Re activity from the W target can be collected on the receiving area of the collector. The apparatus can be used to isolate the ¹⁸⁶Re isotope formed from ¹⁸⁶W upon irradiation with protons or deuterons of cyclotron targets.

已开发出一种用于从辐照钨靶中快速热提取 Re 放射性同位素的装置。在库尔恰托夫研究所的 U-150 回旋加速器上使用用氘核预辐照的钨靶对其运行进行了测试。给出了该装置的设计及其操作原理的描述。已经表明，在一个两阶段的煅烧-升华循环中，至少 89% 的来自 W 靶的 Re 活性可以在收集器的接收区域收集。该装置可用于分离由¹⁸⁶ W 在用回旋加速器目标的质子或氘核照射后形成的¹⁸⁶ Re 同位素。
