Paper Abstract

We have successfully recorded analog signals, using the High-Speed Multi-Channel Data Recorder1 (HSMCDR), where the signal source and the recorder were required to be -2000 m apart. In addition, it was necessary for the system to operate remotely. This photonic data recording experiment consisted of a HSMCDR, laser diode transmitters and the -2000m fiber link between them. Of six transmitters, one was used to provide the HSMCDR trigger. Another transmitter sent the trigger waveform to be recorded by the HSMCDR. The remaining four transmitters converted analog electrical data signals into analog photonic signals for transmission to the HSMCDR. Since all signals were coincident, the analog signals were sent over an additional 200 m of fiber to obtain a 1 μs delay, necessary to allow for delay from trigger pulse to start of streak. The system bandwidth was about 350 MHz. The HSMCDR performed all its trigger monitoring, shutter control, arming, and data transfer functions under the direction of a computer. To assess system performance, we designed and installed self-diagnostic circuits that recorded key timing signals on a fast strip-chart recorder. Although we were only provided with five data channels, the HSMCDR used is a 20-channel system. We assembled this system in two days and were ready for data recording within one week. We will describe the system and present our results. In addition, a second generation HSMCDR built around a streak camera with a large area photocathode and charge-coupled device (CCD) digital readout will be described. This system will record up to 40 channels of data.
