Abstract
Introduction. Infrared Fourier Bruker spectrometer of Vertex 70v type is known to be a high-resolution research device that has a rather high cost. The device manufacturer intends to expand its functional possibilities due to cooperation with western partners with the use of additional attachments to the spectrometer and continuous flow cryostats for temperature dependent measurements.
Problem Statement. The imported attachments are standard-type, not customized and quite expensive. Therefore, the objective of this research is to expand functional capabilities of the spectrometer using Ukraine-made pieces.
Purpose. To design the configuration and to create a cryogenic apparatus for expanding the functional capabilities of Bruker Vertex 70v infrared Fourier spectrometer of (Germany).
Results. The cryogenic apparatus consisting of the cryosystem with temperature controlled within 2.2-330 K based on a helium continuous flow cryostat with a set of special manipulators and the cryosystem with temperature controlled within 80-500 K based on a combined nitrogen cryostat with vacuum refrigerant duct of continuous flow type and integrated reservoir of liquid cryoagent has been created. The developed complex of cryogenic equipment is fully compatible with Bruker Vertex 70v infrared Fourier spectrometer and enables temperature-dependent measurements of infrared transmission, reflection, and photoluminescence spectra.
Conclusions. The designed cryosystems are as good as the best world analogs in terms of technical characteristics and have an essential advantage over them in terms of cryoagent consumption rate.
KeywordsFourier spectrometer, nitrogen cryosystems, temperature-controlled helium
