Parallel Heat Flux Decay Length Study in the COMPASS Tokamak Using MWIR and LWIR Cameras
Vondráček, Petr ; Horáček, Jan ; Pánek, Radomír ; Gauthier, E.
A comprehensive study of a parallel heat flux in a tokamak scrape-off layer (SOL) has been performed in the COMPASS tokamak recently. Specially shaped high field side (HFS) limiter was used to estimate a heat flux radial decay length for small limiter radial misalignment. Long wavelength IR microbolometer and medium wavelength IR InSb camera were used for this purpose. This paper compares results obtained by the means of both cameras and demonstrates observation of very narrow heat flux decay length close to the last closed flux surface (LCFS) independantly on used camera.
Infrared Thermography on the COMPASS Tokamak
Vondráček, Petr ; Horáček, Jan ; Cahyna, Pavel ; Pánek, Radomír ; Uličný, J.
This contribution describes a new slow infrared camera obtained by the COMPASS tokamak at IPP Prague. We focus on the camera limitations affecting the experimental data (temporal and spatial smoothing, time shift). Data time deconvolution used to correct the effect of the long response time of the camera detector is described. The second part of the contribution is devoted to the physic basis for the design of a new fast IR camera system planned for installation in COMPASS during the next year.
The use of thermal imagers for diagnostic machinery and equipment in agricultural operations.
ŠRAMHAUSER, Karel
The main subject of this bachelor thesis is to examine possibilities of machine and device diagnosis by the indirect contact-free method of measurement. This method lacks the necessity of decommissioning a device and its further dismantling. To conduct the research the infrared thermo camera was used due to which the level of wear or lifespan of machines analyzed is evaluated. This research paper deals with the issue of thermal radiation of bodies along with its wavelength. Moreover, the analysis focuses also on basic principles of capturing and recording thermo radiation in thermo cameras. Furthermore, the dependence between temperature, level of load and signs of wear grounded in methodology while observing individual devices are analyzed. Finally, the outcomes of measurements are evaluated.
