The Effect of Detector Shape

So far, in this chapter, the emphasis has been on MDA and its relationship to size of the detector, culminating in a discussion of whether bigger is better, or not There are situations, though, where bigger is clearly not better, where the shape of the detector is more important 

Relative Number of Resolution Throughput to achieve same MDA Relative cost 

The optimum relationship between sample size, detector size and measured energy range is now being paid more attention. The manufacturers now refer to the detector profile . Indeed, current ORTEC catalogues include the PROFILE series of GEM detectors to help buyers select the right detector for their anticipated sample size and shape.
