(1) and (2) we see that the ratio of proton counting rate to alpha counting rate is then
"You can get a number for the average rate over many years, but if you want to get time variations or correlations with sunspots or anything else, you need a much higher counting rate. Until we build better detectors with higher counting rates, we're stuck with large uncertainties in the statistics."
Overall this process takes about 500 s and the counting rate is shown on a logarithmic scale on the left side of Fig.
We expect that the counting rate of neutron [beta]-decay event (in coincidence) will be about 110 [s.sup.-1].
The integral spectra observed in both long and short 10 ms traps were recorded in 50 V steps of [V.sub.0] up to a maximum of 900 V with the same statistical error at each point corresponding to about 1% at the highest counting rate. Approximately [10.sup.6] events were recorded in total [12].
The coincidence counting rate for these double coincidences came to about 0.5 [s.sup.-1] to 1 [s.sup.-1] corresponding to a background suppression factor of about [10.sup.3].
The measurement of this amplitude is an asymmetry in the counting rate of neutrons polarized with and against the direction of the T-violating field.
The experimental counting rate asymmetry is given by [epsilon] = [P.sub.n][A.sub.[gamma]] where [P.sub.n] is the beam polarization; the performance of the [.sup.3]He spin filter cell therefore has a crucial influence on the statistical precision of the [A.sub.[gamma]] result.
