Description
The international CUPID-Mo collaboration for 0νββ experiment uses the NTD photothermal readout system. Based on the exsiting scheme and experience, we plan to use the advanced TES photothermal dual readout detection for Cupid-China 0vββ Experiment next stage. This report focuses on the regulated preparation of TES superconducting thin films working in the temperature range of 10-20 mK. Also, the model construction for the whole physical process of TES photothermal signal reading is explored in this topic. The core structures of TES photothermal detector unit will include: LMO crystal, TES photothermal detector, Si substrate, LMO and weak thermal support structure of photon detector, reflective layer, heat sink and mechanical shell.
Through the 0νββ signal and background discrimination study, we carry out the physical design, preparation and test characterization of TES detector. By constructing and simulating the whole physical process model of TES detector, we can master the influence of TES components parameters on the overall performance of the detector, so as to optimize the TES design.
