用我们研制的一种特殊的酚醛纸层压材料制成的电阻电极，构成了BESIII谱仪的电阻板室（RPC）原型。这些层压板的表面质量上级于其他地方用于建造RPC的酚醛板。还提出了一种调整层合板弯曲度的方法。在过去的几年里，通过使用一些原型RPC进行了广泛的研究。测试表明，通过使用我们的电阻板而不进行亚麻籽油处理制成的原型RPC可以达到与具有亚麻籽油处理的酚醛树脂或电阻玻璃电极的RPC相当的性能水平。在本文中，我们将讨论这些原型RPC的建设。一个原型RPC的测试结果已被监测了一年，将报告。在样机测试结果良好的基础上，北京高能科迪科技有限公司于2004年初开始采用自主研发的技术生产BESIII谱仪μ子识别器的RPC。
The prototype resistive plate chambers (RPCs) for the BESIII spectrometer were constructed by using resistive electrodes made from a special type of phenolic paper laminates developed by us. The surface quality of these laminates is superior to other bakelite plates that have been used to construct RPCs elsewhere. A method for adjusting the resistivety of these laminates was also developed. Extensive studies were conducted by using a number of prototype RPCs in the last several years. Tests have shown prototype RPCs made by using our resistive plates without the linseed oil treatment can achieve the level of performance comparable to RPCs with linseed oil treated bakelite or resistive glass electrodes. In this paper, we will discuss the construction of these prototype RPCs. The test results of a prototype RPC that have been monitored for a year will be reported. Based on favorable test results of prototypes, the RPC production for the muon identifier of the BESIII spectrometer has started at the Beijing Gaonengkedi Science and Technology Co. Ltd. in early 2004 using the technology that we developed.
