The Resistive Plate Chamber detectors (RPC) proposed in the '80s had time resolution of the order of ns, the spatial resolution of the order of cm and counting capability of tens of Hz/cm2. These detectors underwent since then a great improvement in their performances. The improvement in counting capability was obtained decreasing the average counting charge thanks to a very high-performance front-end, which made it possible to switch from the streamer discharge to the avalanche discharge regime. The improvement in time resolution was achieved by decreasing the thickness of the gas gap (MultiGap-RPCs) or increasing the gas pressure (Pestov-RPCs). The improvement in spatial resolution was obtained by measuring the position with the charge weighted centre method by means of a very low noise analogic electronics. In this paper, we suggest the possibility of creating cylindrical RPCs called RCCs (Resistive Cylindric Chambers). We discuss the advantages and disadvantages of the cylindrical configuration, which could allow to obtain high temporal resolution with a single thick pressurized gas-gap. Very preliminary results were obtained with a RCC prototype. Possible application in future experiments are discussed.

未来 RPC 的发展

80年代提出的电阻板室探测器(RPC)具有ns数量级的时间分辨率、cm数量级的空间分辨率和数十Hz/cm 2的计数能力. 从那时起,这些探测器的性能有了很大的提高。得益于非常高性能的前端,计数能力的提高是通过降低平均计数电荷来实现的,这使得从流光放电切换到雪崩放电状态成为可能。通过减小气隙的厚度 (MultiGap-RPCs) 或增加气体压力 (Pestov-RPCs) 来提高时间分辨率。空间分辨率的提高是通过使用非常低噪声的模拟电子设备以电荷加权中心法测量位置来获得的。在本文中,我们建议创建称为 RCC(电阻圆柱室)的圆柱形 RPC。我们讨论圆柱形配置的优缺点,这可以允许通过单个厚加压气隙获得高时间分辨率。使用 RCC 原型获得了非常初步的结果。讨论了在未来实验中的可能应用。
