The flat surface of each sample is coated with black acrylic paint, and along such strip the heat of the light source from the optical head of the TCS meter (Thermal Conductivity Scanner) scans the sample during the measurement.

18 17/11/2017 See more at www.alpine-space.eu/projects/greta 2 rock samples are prepared for thermal conductivity scanning with the TCS meter (GeoZS laboratory)

Two rock samples (from the Cerkno municipality The moving optical head (visible on area) are placed on a flat the left side of the scanner) will platform of the scan both samples. On both sides electronic-mechanical of samples are set appropriately scanner TCS along the selected standards (part of the marked scanned line with meter‘s equipment), depending on the expected thermal conductivity its flat surface and the (TC) to be measured. It is painted strip facing preferable that with one down. measurement the scanning is done simultaneously on the rocks of the same or very similar lithology that are similar to the expected TC.

19 17/11/2017 See more at www.alpine-space.eu/projects/greta Conducting thermal conductivity measurements and processing of their results Operator: Dušan Rajver, MSc During the measurement, the optical head moves under the placed samples along the scanning line, marked on the meter TCS. In the middle of the optical head is the light source of the heat. While scanning, first cool infrared (IR) sensor scans, then the heat source, followed by warm IR sensor. Preparation of parameters following appropriate steps for each measurement is carried out with the TCS program, and the TC measurement itself is computer monitored with this program. Also, the results are processed by this program, for each sample separately.
