Recent developments of in-vessel calibration of mid-IR cameras at JET

Rev Sci Instrum. 2016 Nov;87(11):11D419. doi: 10.1063/1.4960323.


Recent improvements in software tools and methodology have allowed us to perform a more comprehensive in-vessel calibration for all mid-infrared camera systems at JET. A comparison of experimental methods to calculate the non-uniformity correction is described as well as the linearity for the different camera systems. Measurements of the temperature are assessed for the different diagnostics.
