The UVSOR storage ring is a synchrotron radiation light source for studies of molecular science and its related fields. The radio frequency of the ring is 90 MHz [megahertz] and its harmonic number is 16. The pulsed light is supplied with a period of 11 ns, when all buckets of the ring are filled. The storage ring can be operated in the single bunch mode when a longer pulse period is required. In this mode, the period of the pulsed light is 180 ns [nanoseconds], which is the revolution period of the beam in the ring. The single bunch is produced in the booster synchrotron, and it is transferred to only one bucket of the ring. 1, record 7, English, - single%20bunch%20mode

Chip designers pipeline the instructions, or low-level commands, given to the hardware. The first pipelined microprocessors used a five-stage pipeline. (The number of stages completed each second is given by the so-called clock rate. A personal computer with a 200 megahertz clock then executes 100 million stages per second.) Because the speedup from pipelining equals the number of stages, recent microprocessors have adopted eight or more stage pipelines. 2, record 10, English, - pipeline%20microprocessor
