Abstract

The JET gamma-ray camera diagnostics have already provided valuable information on the gamma-ray imaging of fast ion in JET plasmas /1, 2/. The JET Gamma-Ray Cameras (GRC) upgrade project deals with the design of appropriate neutron/gamma-ray filters ("neutron attenuators"). The main design parameter was the neutron attenuation factor /3/. The two design solutions, that have been finally chosen and developed at the level of scheme design, consist of: a) one quasi-crescent shaped neutron attenuator (for the horizontal camera) and b) two quasi-trapezoid shaped neutron attenuators (for the vertical one). Pure light water was chosen as the attenuating material for the JET gamma-ray cameras. Finite Element Analysis (FEA) methods used to evaluate the behaviour of the filter casings under the loadings (internal hydrostatic pressure torques) have proven the stability of the structure.
