LHAASO WFCTA实验的主要科学目标是测量从10 TeV到1 EeV的宇宙射线能谱和成分。切伦科夫望远镜的SiPM相机测量的广泛的空气簇射中的切伦科夫光子可以用来重建宇宙线能量。相机的绝对标定是实现宇宙线能谱精确测量的关键步骤。研制了一种基于LED的多波长柱面照明器，安装在望远镜内部，用于相机的标定和监控，在-26 ~26 ° C的温度变化范围内，照明器的稳定度优于0.5%。研制了一种单电子分辨力为21.6%的便携式探头。经过中国计量科学研究院（NIM）的校准后，该探测器被带到LHAASO现场测量望远镜内圆柱照明器的绝对光子密度。基于已知光子密度的照明器，可以标定相机的光子转换因子，总体标定不确定度小于2.6%。
The main scientific goal of the LHAASO WFCTA experiment is to measure the cosmic ray energy spectra and composition from 10 TeV to 1 EeV. Cherenkov photons in the extensive air shower measured by the SiPM camera of Cherenkov telescopes can be used to reconstruct the cosmic ray energy. The absolute calibration of the camera is a crucial step to achieve the accurate measurement of the cosmic ray energy spectrum. A multi-wavelength cylindrical illuminator based on LEDs is developed and mounted inside the telescope to calibrate and monitor the camera, and the illuminator’s stability is better than 0.5% under the temperature variation from-26 to 26° C. A portable probe with a single photoelectron resolution of 21.6% is developed. After calibration by National Institute of Metrology, China (NIM), the probe is taken to the LHAASO site to measure the absolute photon density of the cylindrical illuminator inside the telescope. Based on the illuminator with known photon density, the photon conversion factor of the camera can be calibrated, and the overall calibration uncertainty is less than 2.6%.
