描述了一种仅使用一组微通道板、波形数字化仪、荧光屏和CMOS相机的新型多粒子时间和位置敏感探测器。将通过快速数字化从微通道板获取的定时信息分配到由相机记录的位置是基于荧光屏斑点的亮度（定义为它们的积分强度）和电信号的幅度（COBRA）之间的相关性。通过观察HeH的解离，H3的分裂成两个或三个片段，和氙原子的光双电离进行的测试，这说明了COBRA检测方案的性能。
A new multi-particle time and position sensitive detector using only a set of microchannel plates, a waveform digitizer, a phosphor screen, and a CMOS camera is described. The assignment of the timing information, as taken from the microchannel plates by fast digitizing, to the positions, as recorded by the camera, is based on the COrrelation between the BRightness of the phosphor screen spots, defined as their integrated intensity and the Amplitude of the electrical signals (COBRA). Tests performed by observing the dissociation of HeH, the fragmentation of H3 into two or three fragments, and the photo-double-ionization of Xenon atoms are presented, which illustrate the performances of the COBRA detection scheme.
