Abstract

The invention belongs to the technical field of alpha nuclide measurement, and particularly relates to an alpha nuclide sample source electro-deposition sample preparation device which comprises a plurality of sample preparation units arranged on an equipment base (13), the sample preparation units can conduct electro-deposition operation on alpha nuclide sample sources, and electro-deposition tanks (7) and cooling tanks (8) on the sample preparation units are made of transparent glass materials. The device is simple in structure, low in price and easy to replace, cross contamination is prevented, the PH value of electro-deposition liquid can be conveniently adjusted, changes of the electro-deposition liquid can be conveniently observed, and the electro-deposition process can be stably controlled; the device has the advantages that the cooling temperature is easy to control in the alpha nuclide electro-deposition process, cross contamination is not prone to occurring, and integration is high, the stability of the alpha nuclide electro-deposition process is improved, a high-quality alpha nuclide sample source is prepared, and the requirement for alpha nuclide monitoring is met.

Description

technical field [0001] The invention belongs to the technical field of alpha nuclide measurement, in particular to an alpha nuclide sample source electrodeposition sample preparation device. Background technique [0002] The α-spectrometer method is the basic method for the measurement of α-nuclides, which has the characteristics of high sensitivity and simple operation. The alpha spectrometer has high requirements for the alpha nuclide sample source: thin and uniform, firm electroplating layer, and high electrodeposition rate. Therefore, a stable and reliable electrodeposition sample preparation device is very important to prepare a sample source that meets the requirements. [0003] At present, most of the electrodeposition device systems in the laboratory are temporarily built in the laboratory: electrodeposition tank, stable power supply, and cooling tank. The electrodeposition tank is processed in accordance with the standards of HJ 814-2016 "Radiochemical Analysis of...
