ME CALIBRATIONS - ERRATUM
Unfortunately, there were a number of errors in the recent article on ME calibrations in the Express (No. 10, p.40-44). My apologies for any inconvenience caused.
1. Xenon Resolution Function
The Xenon resolution ( V/V; as a percentage) is given by:
Res = Nl+N2/SQRT(E) + N3 x E+ N4 x E3 (E
Res = N6 + N7 x E (E>N5)
The extra term is then added (as given in the Express article) as:
Res = SQRT(Res x Res + (N8 x 20/E)2)
2. Xenon Gain Coefficients
A2 should be given by A2 = A2/(DG+1.0) and not A2/(DGxl.O) as in the Express article. Also for consistency, TX ='t - T1 should be replaced by TX = t -T Fud although for Xenon T1 = TFud.
3. Argon Gain Coefficients
In order to make the method of applying the gain correction more apparent the three lines:
Al = Al + DGI
