Patent ID: 6949962

Claim:
Device for improving a signal provided by a particle detector ( 2 , 32 ), said detector being able to provide current pulses when said detector receives particles, said device comprising means ( 8 , 10 ; 28 , 34 , 36 ) for transforming current pulses into voltage pulses, said device being characterised by further comprising: means ( 16 , 18 ; 40 , 42 - 60 - 62 , 44 ) for detection of a voltage extremum between a voltage pulse provided by the transforming means and a following voltage pulse, means ( 12 ; 30 , 52 , 54 ) for subtracting the value of the extremum thus detected from the voltage pulse provided by the transforming means, in such a way as to improve the corresponding signal, provided by the detector, and means ( 20 , 46 ) for resetting the extremum.
