STRIKE panel layout: cable path and surge protectors

STRIKE (Short - Time Retractable Instrumented Kalorimeter Experiment) is a diagnostic which will be used to characterize the SPIDER beam, by measur ing beam uniformity, beam divergence and stripping losses. STRIKE will be composed of 16 panels (396mm x 160 mm x 20 mm each), usually called tiles, made out of 1D - CFC. The tiles are surrounded by kerbs to collect beam halo and strips are used to occlude the gaps which are foreseen in between two adjacent tiles to permit thermal expansion. Both kerbs and strips are made out of graphite. To determine the beam features, STRIKE tiles will be observed from behind with two infra - red camera s to determine a 2D pr ofile of the beam power deposition. In addition, the current impinging on each tile, strip or kerb will be measured; each tile will be equipped with two thermocouples, and the temperature of each kerb and strip will also be measured by a thermocouple. STRI KE design foresees also the use of Langmuir probes and tiles biasing to reduce the ef fect of the secondary electrons . STRIKE is then a complex system, equipped with many diagnostics. The use of such a large amount of diagnostics requires a smart cables lay out. In addition a s breakdowns may occur then, the installation of surge protectors is also foreseen . The present contribution f ocuses on the cable layout, the choice and the positioning of surge protectors . Technical note [ 2 ] should instead be taken as a general reference for STRIKE panel design.
