These experiments include rotation scans determining the focal full width half maximum (FWHM), transmission measurements, test of different collimator lamellas and performance tests of the cooling of the filter.
The electrocatalytic kinetics for H2O2 reduction at rotating FePP/PG disc electrode was investigated with a rapid rotation-scan method, and the rate constants (k) at various pH values and potentials were measured.
Because it has the property of rapidity, accuracy and high reproducibility, the rotation-scan method is applicable especially to studying electrochemical systems that are not sufficiently stable.
A linear rotation-scan rde and rrde theory was derived and investigated for the electrochemical reduction of K3Fe CN 6 and the electrochemical oxidation of ascorbic acid.
The rate constant of ascorbic oxidation of PG electrode in pH 7.2 buffer solution was measured using the linear rotation-scan method.
If the activity of electrode is quite stable, the i ω curves obtained from the linear rotation-scan (whose current deviation has been corrected by a method of plotting) cannot vary with the rotation-scan rate of electrode (10 s 1000 rpm s−1), and the forward and backward scans are repeated.
Soc.117, 1033 (1970)], some kinetic parameters for the electrocatalytic reduction of O2 by VB12 ad)/GC have been determined rapidly by using a linear rotation-scan method [Rongzhong Jiang and Shaojun Dong, Electrochim. Acta35, 1451 19900)].
If the electrode activity is not stable enough, the current in the higher ω value part of i ω curve will change to a lower value than the normal, leading to a separation between the forward and backward scans with decreasing rotation-scan rate of electrode.
The attenuation CT was a helical 0.5-s rotation time scan, employing 120 kV and 30 mA.
By contrast, the unimproved fractal algorithms can result in significantly slower rotation of scan line or even simulation failure.
