We have been developing a concentrated constant type mechanical inductance detector for alpha-ray cameras. However, the quasiparticle lifetime of niobium is more than three orders of magnitude shorter than that of aluminum. As a solution to this problem, we propose a LEKID with an air bridge structure. This structure allows the energy to be retained in the LEKID for a long time, and the relaxation time is expected to be prolonged by many Cooper pair breakdowns, which is expected to improve the energy resolution.Translated with www.DeepL.com/Translator (free version)
