Quench index parameter

In Figure 1 below, an arbitrary example is given of how the uncertainty in the quench index parameter results in an uncertainty in the interpolated efficiency and, under common LS conditions with moderate to high quench levels, the influence of the quench index parameter is often neglected. 

Figure 1 Example of uncertainties in quench index parameter and how this results in an uncertainty in the interpolated efficiency. The decreasing efficiency at lower quench levels (quench index > 500) is caused by the window setting of 4-50 keV High energy pulses escape the window.

This paper has demonstrated that the uncertainty of a LS quench curve is not only calculated by the source imcertainty and the counting of the LS quench set. The fitting procedure of the quench curve and the uncertainty of the quench index parameter also play an important role in the total uncertainty. This is especially valid under heavy qnench conditions where the slope of the quench curve is large. 

The lattice parameters of all rare earth tiifluoride modifications are also listed in table 1. They represent room-temperature data except for the a-forms of ErFs-LuFs and YF3. Because these high-temperature phases cannot be quenched, one relies on high-temperature diffraction data which are only reported by Thoma and Brunton (1966). Their data, however, have been re-indexed by Sobolev and Fedorov (1973) on the basis of a smaller unit cell, (utb = VSusf, Ctb = 2csf, Ztb = 6Zsf), the lattice parameters of which are listed in table 1. Sobolev and Fedorov (1973) found also that this so-called a-Yp3 type is...
