Spectroscopic measurements on the Joint European Torus using optical fibers to relay visible radiation
- 1. JET Joint Undertaking, Abingdon, Oxon, 0X14 3EA, United Kingdom
Description
Light from the Joint European Torus (JET) tokamak is relayed by optical fibers to detectors outside the biological shield, where personnel access is unrestricted. This arrangement, which is described in detail, will permit routine recording during the intense neutron emission associated with the production of D--T plasmas: scheduled for 1989. The diagnostic has been in routine use since JET began operation in mid-1983. A selection of results obtained is presented. The likely degradation in fiber performance, due to irradiation, during the D--T phase of the program is assessed. Methods of overcoming the problems due to induced absorption are presented
