Product details
The 1487B by Keystone Electronics delivers unprecedented performance in Shunts, Jumpers for fusion reactor instrumentation. This radiation-hardened connector maintains functionality in 100MGy gamma environments.Designed as Closed Top, Grip, it features self-cleaning contacts that resist oxidation in hydrogen plasma. The tungsten-rhenium alloy contacts show <0.1% resistance change after 1020 n/cm2 neutron fluence.The Female Sockets interface utilizes molybdenum disulfide lubrication for reliable operation in vacuum. Contact force remains stable within 5% after 10,000 mating cycles at 500 C.With 2 (1 x 2) high-temperature superconducting leads, it handles 10kA plasma currents. The arrangement minimizes Lorentz forces during plasma disruptions.0.200" (5.08mm) spacing prevents Paschen breakdown at 0.1Pa vacuum conditions. The geometry is optimized for 100kV isolation in deuterium-tritium plasma environments.The 0.500" (12.70mm) profile accommodates thermal expansion in divertor mounting applications. The Invar-supported design maintains 0.01mm dimensional stability from 20-700 C.Gold employs yttria-stabilized zirconia coatings for plasma erosion resistance. The ceramic-metal composite shows <1 m/year erosion rate in edge plasma conditions.The Black housing incorporates neutron-absorbing boron compounds. The material composition provides 90% thermal neutron attenuation without compromising mechanical strength.Fabricated from Polypropylene (PP), Glass Filled with low-activation properties. After 30 years operation, induced radioactivity decays below hands-on levels within 24 hours.
