SU1226214A1 - Thermostatic chamber of radiospectrometer - Google Patents

Abstract

The invention relates to the field of experimental physics, in particular to the design of thermostats for radio spectrometry measurements. The purpose of the invention is to ensure the reliability of electromagnetic shielding of a coil, the convenience of changing the sample under study and the smallness of temperature gradients. For this purpose, the chamber is made of a thin-walled tube, which is a screen for the coil, and a tube with double walls. Both pipes have openings for the passage of the heat transfer gas, and the thin-walled pipe is freely inserted into the double-walled pipe so that the holes in the pipes coincide. In this case, the coolant passes inside the thin-walled tube and in the cavity between the double walls in opposite directions. 1 il. i (L С to 4ib

Description

The invention relates to the field of experimental physics and can be used in devices for stabilizing and regulating the temperature of a sample under study during radio spectroscopic measurements.

The purpose of the invention is to improve the electromagnetic shielding of the spectrometer package, improve the convenience of changing the sample and the coil and the design technology.

The drawing shows the camera, a longitudinal section.

The chamber contains a thin-walled pipe 1 with a coaxial connector 2 and holes 3, a pipe 4 with double walls with holes 5 and 6 Inside the thin-walled pipe 1 there is an inductor 7 and test sample 8. The entire device is surrounded by a thermal insulator 9 .

The camera operates as follows. In the working position, the pipe 1 is pushed into the pipe 4 so that the lines 3 and 5 coincide. The heat transfer gas is fed into the open end of the pipe 1, blows the sample 8, through the holes 3 and 5 into the cavity between the double walls of the pipe 4 and then into the outlet holes 6..

DP of the inductor coil 7 or sample 8, pipe 1 must be pulled out of pipe 4. Pipe 1 moves with the spectrometer sensor with which it is connected by connector 2. Then it is enough to replace pipe 1 with an identical one but with another coil 7, or replace sample 8 and back to working position.

Tubes 1 and 4 for providing electromagnetic shielding of the coil, smallness) —the temperature gradients in the sample and the mechanical strength of the device are made of well-electrically and heat-conducting metals, such as brass or copper. In order to achieve the greatest technological effectiveness of the construction, the chamber of pipes 1 and 4 may have a cylindrical shape.
