Parallel Configuration For Fast Superconducting Strip Line Detectors With Very Large Area In Time Of Flight Mass Spectrometry

We realized a \ery fast and large Superconducting Strip Line Detector based on a parallel configuration of nanowires. The detector with size 200×200 μm2 recorded a sub‐nanosecond pulse width of 700 ps in FWHM (400 ps rise time and 530 ps relaxation time) for lysozyme monomers/multimers molecules accelerated at 175 keV in a Time of Flight Mass Spectrometer. This record is the best in the class of superconducting detectors and comparable with the fastest NbN superconducting single photon detector of 10×10 μm2. We succeeded in acquiring mass spectra as the first step for a scale‐up to ∼mm pixel size for high throughput MS analysis, while keeping a fast response.
