Cable

From MariachiWiki

Co-axial cables are used to transmit the electronic pulses between the detectors, oscilloscopes, and logic units. For the very fast pulses we are using, the length of cables must be considered carefully, because the time it takes for the signals to move along the cables (propagation time) can be a factor in our measurements. It takes about 1 nanosecond (10^-9 seconds) for a signal to travel 8" in a (50 Ohm) co-axial cable. We can use this fact to bring the discriminated signals from several detectors to a Logic Unit (WISE Course) or a custom designed "electronics box" so that they create a "coincidence". Similarly we can measure the delay between signals by inserting or removing additional cable lengths.
