← BACK Research Xihu TPC and NOAr prototype 2026-09-07 NOAr / Local TPC Hands-on detector research at Westlake Our local TPC platform brings together detector assembly, cryogenic operation, photosensor testing and data analysis. We use liquid argon and liquid xenon to study detector response and develop readout systems. NOAr explores single-phase liquid-argon readout with fine electrodes and SiPM arrays. NOAr single-PDU animation. Watch the animation. NOAr single-PDU assembly and internal structure. Undergraduate students welcome Join us for hands-on laboratory internships in detector assembly, photosensor testing, data acquisition and analysis. Contact us about an internship → Simulation and SiPM readout A 4 × 4 SiPM module brings photosensors and readout electronics together. Electric-field simulations guide the fine-electrode geometry, electron transport and insulation design. SiPM readout-board design Prototype SiPM readout-board layout. Local electric-field simulation Calculated field near an electrode. Our local TPC platform Westlake liquid-argon optical-readout test assembly. Xihu TPC supports detector assembly, cryogenic operation, purification, slow control and waveform acquisition. Liquid-argon studies cover cryogenic SiPM response and single-photoelectron calibration. Liquid-xenon data support S1/S2 reconstruction and charge-transport studies, alongside detector-response modelling.
