Maximum tracking rate

This maximum accuracy is attained only when the tracer is at a minimum distance from the detector. For particle-tracking measurements, the system must be able to measure accurately in a range of distances. Let the closest working distance be denoted r0 where the maximum count rate umax is obtained. Then, the count rate at a mean working distance rm is... [Pg.374]

If gas mixtures with concentrations varied over several orders of magnitude are needed, dosing the gas must be carried out via several dosing tracks with different flow rates. As is the case with many other measuring and control instruments, a percent rate of error, e, is specified when using the MFC technique. As the value refers not to the actual but to the maximum flow rate of the MFC (Fs,MFC-max)> not a relative error but an absolute flow error (A I mfc... [Pg.158]

Equation (7.9) implies that nothing survives radical-radical recombination for an isolated cylindrical track—that is, at zero dose. At a finite dose rate, tracks will overlap at a large, but finite time and, for even a very small solute concentration, a scavenger reaction may precede intertrack overlap. Thus, the relevant question is the determination of the maximum time to be used in Eq. (7.9) consistent with a given dose rate. [Pg.203]

The deuterium KIE values are generally in the range expected for linear three-center hydrogen transfer reactions,44107 and they track nicely with the rate constants for the reactions with the faster, more exothermic reactions displaying smaller KIEs. The large KIE value for reaction of the benzyl radical is noteworthy in that it exceeds the theoretical maximum for the classical model in a manner apparently similar to that seen with tin hydride (see below). [Pg.103]

The rate of energy loss from the particle per unit length of track, or Linear Energy Transfer (LET), was known to follow the Bragg curve with a maximum LET close to the end of the particle s track. Be the (1933(8)) derived theoretical expression for this quantity for electrons and other charged particles. For electrons this has the form ... [Pg.6]

In Figure 3, the response is shown when K = Z, the maximum flowrate is 600 gal/min, and the emptying rate varies from 300 to 100 gal/min. As can be seen by the response, the controller adjusts the feedrate (into tank Tz) to track the changes in the emptying rate (out of tank T ) and still achieve the target fill time. ... [Pg.93]

Fluoropolymers are, generally, very stable at or below their specified maximum use temperatures. The rate of degradation of these plastics at higher temperatures is a function of their chemical stmc-tures in addition to temperature, time at temperature, and, to some extent, on the pressure and the atmosphere of decomposition. In actual processing, degradation is tracked by indirect measurement of molecular weight. Thermal exposure leads to a reduction in the molecular weight, which can be quantified by an increase in the MFR, heat of fusion of polymer, and in specific controlled measurements. [Pg.86]
