摘要:

国际轴子观测站(IAXO)是一个大型轴子太阳望远镜,它将以前所未有的灵敏度寻找太阳中产生的轴子和类轴子粒子。BabyIAXO是一个中间实验阶段,将在DESY(德国)进行,它将测试所有IAXO子系统,作为IAXO的原型,同时也是一个具有发现潜力的成熟的太阳望远镜。该项目的一个关键组成部分是超低背景X射线探测器,它将对实验中轴子转换产生的X射线光子进行成像。用于此目的的基线探测技术是Micromegas(Microbulk)探测器。我们将展示为BabyIAXO实现极具挑战性的背景水平所做的探索和策略,这需要一种多途径策略,包括地面测量、探测器部件的筛选活动、地下测量、背景模型、现场背景测量以及强大的排除算法。将展示BabyIAXO原型调试的初步结果。

英文摘要:

The International AXion Observatory (IAXO) is a large scale axion helioscope that will look for axions and axion-like particles produced in the Sun with unprecedented sensitivity. BabyIAXO is an intermediate experimental stage that will be hosted at DESY (Germany) and that will test all IAXO subsystems serving as a prototype for IAXO but at the same time as a fully-fledged helioscope with potential for discovery. One of the crucial components of the project is the ultra-low background X-ray detectors that will image the X-ray photons produced by axion conversion in the experiment. The baseline detection technology for this purpose are Micromegas (Microbulk) detectors. We will show the quest and the strategy to attain the very challenging levels of background targeted for BabyIAXO that need a multi-approach strategy coming from ground measurements, screening campaigns of components of the detector, underground measurements, background models, in-situ background measurements as well as powerful rejection algorithms. First results from the commissioning of the BabyIAXO prototype will be shown.
