We have been developing a high-resolution superconducting time-of-flight mass spectrometry (TOF-MS) system, which is composed of a superconducting strip ion detector (SSID) and a single-flux-quantum (SFQ) multi-stop time-to-digital converter (TDC). In our previous study, we demonstrated our SFQ TDC using the AIST Nb standard process 2 (STP2). In this study, we installed the SFQ TDC into a cryo-cooler and implemented a superconducting TOF-MS system by using the SFQ TDC and an SSID. We analyzed the TOF of biomolecules, Lysozyme, where the molecular weight is 14,000 Da, and obtained the mass spectrum. |
