摘要:

我们用一个由4 T × 2.3m超导磁体、PIN光电二极管X射线探测器和一个跟踪太阳的地平仪组成的探测器寻找太阳轴子。转换区域充满冷氦气,其修改相干转换发生时的轴子质量。在过去的测量中,已经扫描了从0到0.27eV的轴子质量。由于没有看到积极的证据,轴子-光子耦合常数的上限被设定为g < 6- 10 E-10/GeV(95%CL),这取决于轴子的质量。我们现在正在积极准备一个新阶段的实验,目标是一个到几个电子伏的太阳轴子。在这个质量区域中,我们的探测器可能能够检查比轴子模型更好的参数区域。

英文摘要:

We have searched for solar axions with a detector which consists of a 4T x 2.3m superconducting magnet, PIN-photodiode X-ray detectors, and an altazimuth mount to track the sun. The conversion region is filled with cold helium gas which modifies the axion mass at which coherent conversion occurs. In the past measurements, axion mass from 0 to 0.27eV have been scanned. Since no positive evidence was seen, an upper limit to the axion-photon coupling constant was set to be g < 6-10E-10/GeV (95%CL) depending on the axion masses. We are now actively preparing for a new stage of the experiment aiming at one to a few eV solar axions. In this mass region, our detector might be able to check parameter regions which are preferable to the axion models.
