	A carbon fiber composite (CFC) target calorimeter has been installed to study the power density distribution of the neutral beams in situ. The thermographic print of the beam can be recorded using an infrared camera, permitting a reliable analysis due to the highly anisotropic thermal conductivity of the target material. Direct conversion from temperature to power density is possible due to independent thermocouple measurements on two adiabatically mounted copper buttons. With the combined thermographic and calorimetric measurements it has been possible to determine the power density distribution of the beams.
