The Second LHAASO Collaboration Conference in 2026 & The Academic Symposium for the 10th Anniversary of the LHAASO collaboration

IN cosmic ray EAS experiment, it is neccessary to combine hadronic component, electromagnetic compoment and muon component to determine energy and then obtain all particle energy spectrum. ENDA-64 keeps on running and taking data at the LHAASO site. Since Jan. 2025, EAS thermal neutron sampling time has been set 5 ms for 21 months to reduce background. Detected thermal neutrons of all data are corrected according to calibration results by using neutron beam test. Moreover, detected thermal neutrons of all data in both dry season and rain season are corrected with soil moisture measurement. Different hadronic interaction models are compared in simulation. Beyond these progresses, difference between analysis results of real data and those of simulation data becomes much smaller. The upgraded all particle energy spectrum of cosmic ray around the knee region determined with electrons, muons and thermal neutrons by using coincident events between ENDA and KM2A is obtained, and systematic uncertainty is considered.
