high count rate造句

• With high count rates or slow detectors ( MCPs with phosphor screen or discrete photomultipliers ) pulses overlap.
• IXO optics and instrumentation will provide up to 100-fold increase in effective area for high resolution spectroscopy, deep spectral, and microsecond spectroscopic timing with high count rate capability.
• This colloquial name stems from the early days of automatic counting, when a scaling circuit was required to divide down a high count rate to a speed which mechanical counters could register.
• This causes a loss of counts at sufficiently high count rates and limits the G M tube to an effective ( accurate ) count rate of approximately 10 3 counts per second even with external quenching.
• This colloquial name comes from the early days of automatic radiation counting, when a pulse-dividing circuit was required to " scale down " a high count rate to a speed which mechanical counters could register.
• Ironically the very high count rates obtained in TSC mechanisms ( as compared with PMTIMER or the Intel HPET device ) can cause a problem that the measurable time intervals are too short : there is an upper limit to the usefulness of a counter that overflows early.
