Centroid finding method for position-sensitive detectors

Evaluation of systematic errors in the avalanche localization along the wire with cathode strips read-out MWPC

“…3 the influence of the parameter 2 a/D on the size of the systematic error at the 1/4 position and for zero bias. One can see that this parameter has a drastic effect on the systematic error for values 2a/D> 1.1; for values 2a/D slightly smaller than I. one obtains very small systematic errors, in agreement with the measurements of Radeka and Bole [8]. The optimization by Gatti et al [6] suggests 2a/D For a wire spacing of 2 mm.…”

“…This has been demonstrated for example in the localization of electromagnetic showers using a strip or cell segmented calorimeter [7]. In the case of track localization by the COG determination in a proportional chamber, Radeka et al [8] 3) and from this the systematic error in the determination of the charge centre for six different estimation algorithms. The errors thus calculated were Used to correct their measurements.…”

Using an electron beam energy scan to characterise a silicon strip telescope

“…4 A simple parametrisation of the intrinsic resolution of a silicon detector is given in Ref. [12], resol ¼ 2:2 Ã pitch=ðS=NÞ.…”

X‐ray imaging with gas proportional detectors

“…Like the delay line technique, these are all capable of dealing with only one photon at a time, but in general the delay line offers the lowest electronic noise and highest count rate capability, though with more physical components. Multiple readout centroid finding systems (14) have even lower electronic noise, at the expense of more complexity.…”
