Pulse pile-up discrimination system
First Claim
1. A pulse pile-up discrimination system for a multicell detector comprising:
- means for accumulating a charge on each cell to detect its response to a radiant emission impinging on an unknown position on the detector;
means, responsive to the charge on each cell, for establishing the position of impingement of the radiant emission on the detector;
a pulse pile-up discriminator, responsive to said means for establishing the position of impingement, for providing associated with each impingement position at least lower and upper discrimination levels of a function of the distribution of charge on the cells indicative of a pulse pile-up;
means for generating a function of the distribution of charge on the cells in response to said radiant emission impinging on said unknown position of said detector; and
means for comparing said function of the distribution of charges on the cells in response to said radiant emission impinging on said unknown position of said detectors to said lower and upper discrimination levels of a function of the distribution of charges provided by said pulse pile-up discriminator to determine whether a pulse pile-up has occurred.

Abstract
A pulse pile-up discrimination system for a multicell detector accumulates a charge on each cell to detect its response to a radiant emission impinging on an unknown position of the detector; the position of impingement of the radiant emission is established in accordance with the charge on each cell; a pulse pile-up discriminator provides, associated with each impingement position, lower and upper discrimination levels of a function of the distribution of charge on the cells indicative of a pulse pile-up; a function of the distribution of the charge on the cells is generated in response to the radiant emission impinging on the unknown position of the detector; the function of the distribution of charges on the cells in response to the radiant emission impinging on the unknown position of the detectors is compared to the lower and upper discrimination levels of a function of the distribution of charges provided by the pulse pile-up discriminator to determine whether a pulse pile-up has occurred.
