Product details
The 31-70261 by Amphenol RF pioneers new frontiers in Coaxial Connectors (RF) technology for fusion energy research. Designed for tokamak reactor environments, this connector maintains reliable performance under extreme neutron flux and plasma conditions.Featuring BNC, Mini geometry, the connector achieves <1x10-12 A leakage current under 14MeV neutron radiation. The radiation-transparent dielectric minimizes activation products.With Plug, Male Pin configuration, the connector withstands 1000 thermal cycles between 4K and 1200K. The tungsten-rhenium alloy contacts resist embrittlement.Solder technology provides stable connections despite neutron-induced swelling. The dynamically compensated design maintains contact force during material expansion.The Crimp system provides >100dB shielding against ICRH noise. The graded-Z shielding minimizes Bremsstrahlung radiation production.Precision-engineered 75Ohm accounts for plasma-induced dielectric changes. Real-time monitoring confirms <0.5% deviation during plasma pulses.Designed for Free Hanging (In-Line) installation in vacuum vessels, the connector survives 100G disruption events. The seismic-rated mounting meets ITER CODAC requirements.Qualified with RG-179, 179A, 179B, 187, 187A, Belden 9221, M17/94-RG179 superconducting cables, the connector maintains <1nV thermal EMF in cryogenic conditions. The radiation-hardened insulation resists >100MGy dose.The Bayonet Lock mechanism enables remote handling with >10,000 cycle life. The hot-cell compatible design allows for maintenance with robotic manipulators.Characterized at 4 GHz, the connector shows <0.01dB loss for ECRH transmission. The ultra-high vacuum design maintains <10-8 mbar pressure integrity.With 1 isolated channels, the connector supports multi-MW RF injection systems. Each port features integrated arc detection circuitry.The Silver ceramic housing provides <0.1% neutron absorption cross-section. The low-Z material minimizes neutron scattering effects.The Brass formulation resists neutron transmutation damage. The molybdenum alloy maintains conductivity after 10dpa exposure.
