TCLK

Also known as Clock, (Tevatron). Although the name implies it is only used for the Tevatron, it is essentially the master clock for the accelerator complex. It operates at a 10 MHz rate and is able to transmit encoded events at about a 1 MHz rate. There are 256 possible events (displayed in 2-digit hexadecimal numbers) that the clock can send out.
