Our nuclear fusion diagnostic systems for plasma physics experiments have had many years of worldwide success in nuclear fusion devices. The bolometer system is a diagnostic for absolute measurement in the soft x-ray to infrared range, in order to measure the radiation losses spatially and temporally resolved in plasma machines.
The bolometer (dimensions: 20x33x15 mm3) is a highly integrated four-channel detector with independent metal resistor bridges. It has functioned successfully for many years in world wide nuclear fusion experiments.

The ASDEX pressure gauge system is a well-established diagnostic for the measurement of neutral gas density in nuclear fusion experiments. The system has especially been developed for operation in high magnetic fields, under noisy conditions and high temperatures. It has performed very reliably in world wide fusion experiments for many years.
