摘要

在大型强子对撞机的实验中，发现LHCb多线比例室的阴极上形成了纳米碳结构。纳米碳结构在铜阴极上的出现引发了比例腔中自发产生的自维持电流。发射中心的增长是由于气体混合组分在铜阴极上的解离产物的吸收。该过程在正常条件下发生，这对纳米结构来说是不寻常的，并且在实验室老化试验中无法重现。

Study of Nanocarbon Spontaneous Emission Centers on the Cathodes of Multiwire Proportional Chambers of the LHCb Muon Detector

It is found that nanocarbon structures are formed on the cathodes of multiwire proportional chambers of the LHCb muon detector as a result of long-term operation in experiments at the Large Hadron Collider. The appearance of nanocarbon structures on the copper cathode initiates spontaneous generation of self-sustained currents in proportional chambers. Emission centers grow due to absorption of dissociation products of gas mixture components on the copper cathode. The process occurs under normal conditions, which is unusual for nanostructures, and it is not reproducible in laboratory aging tests.
