In the first series of tests a commercial infrared heater is tested to answer the following questions:  • Is it possible to reach heat flux densities up to 500 kW/m² at a temperature of 500°C on the surface of the target? • How homogeneous is the heat distribution? • How many cycles is the heater able to withstand?  Summary Goals Achieved Surface heat flux 500 kW/m² 470 kW/m² Surface temperature 500°C >550°C Homogeneity of heat distribution +/- 5% of nominal value +5.2/-3 % of average value (below heaters) Lifetime 3000 cycles with 400 s at max. power 226 cycles Water cooled through Ø 12 mm hole 800 s test run with 3 heaters at maximal heating power of 45 kW. The distance of the heater filaments to the target surface was 14 mm and between the center of heaters 36 mm.
