Automated measurement of bolometer line of sight alignment and characteristics for application in ITER

Más información sobre el libro

The line of sight (LOS) alignment and characteristic of a bolometer camera used in a fusion experiment is a crucial parameter for the measurement accuracy of the diagnostic. A robot based LOS measurement device has been developed which allows the fully automatic measurement of the two dimensional transmission function of a bolometer camera. It has been used to optimize camera prototypes for ITER and has been successfully operated in the fusion experiment ASDEX Upgrade in order to measure the LOS alignment.
