Fig. 3: Particle detection during transport.
a, FFT spectrum of the image-current signal showing the thermal noise of the superconducting LC circuit shorted by the trapped proton cloud at their axial frequency νz (ref. 29). b, Plot of the fitted dip width of the proton cloud during transport. The blue line with the surrounding faint blue bar is the mean value of the proton cloud before the transport, with its 1σ uncertainty to visualize the efficiency of the transport. The vertical red and green bars in b indicate the transport on the crane and the truck, respectively.
