We present the use of optical power transmission as a
possibility to power electronic components like an LNA
inside the magnet without needing to use copper cables.
The use of switching DC-to-DC converters inside high
magnetic fields is evaluated, and SNR measurements are
presented to compare the performance of different
receive coil setups.
