摘要: Abstract Future Collider Physics Detectors are envisioned with large granularity but we have a power delivery problem unless fill fraction of the detector volume copper conductors. LHC electronics is powered by transporting direct current over distances 30 to 150 meters. This how Thomas Alva Edison his light bulb. For example, CMS ECAL uses 50 kiloamps at 2.5 volts, supplied cable set transmission efficiency only 30%. The loss becomes waste heat in that has be removed. We been exploring methods transmit DC higher voltage (low current), reducing final low (high current) using DC-DC converters. These converters must operate high magnetic fields and radiation levels. requires rad hard components non-magnetic (air core) inductors.
