用多阴极计数器寻找隐藏光子CDM
On a Search for Hidden Photon CDM by a Multi-Cathode Counter
摘要：
报道了一种新的多阴极计数器（MCC）技术，用于寻找质量在5~500 eV之间的暗光子冷暗物质（CDM）。该方法是在假设HP光子混合导致单电子从金属阴极的发射，如果隐藏的光子的质量大于金属的功函数的建议。测量的HP效应应取决于金属的功函数和用作阴极的金属的电子壳层的结构。这可能用于验证所获得的结果。混合参数X的上限的一些初步结果已经获得了HP的质量从5 eV到10 keV作为一个纯粹的说明这种技术的潜力。正在继续努力改进数据处理程序和改进管理协委会的工作。一个设计更先进的新探测器正在建造中。
英文摘要：
We report on a new technique of a Multi-Cathode Counter (MCC) developed to search for hidden photon (HP) cold dark matter (CDM) with a mass from 5 to 500 eV. The method is suggested in the assumption that HP-photon mixing causes emission of single electrons from a metal cathode if the mass of hidden photon is greater than a work function of the metal. The measured effect from HP should be dependent on work function of the metal and on the structure of electronic shells of the metal used as a cathode. Potentially this can be used for a verification of the results obtained. Some preliminary results for the upper limit for mixing parameter X have been obtained for HP with a mass from 5 eV to 10 keV as a pure illustration of the potential of this technique. The efforts are continued to refine the procedure of data treatment and to improve the work of MCC. A new detector with a more developed design is under construction.
