In this paper a very sensitive ion collection device, for diagnostic of laser ablated-target plasma, is described. It allows for reducing down to few microvolts the signal threshold at digital scope input. A standard ion collector is coupled to a transimpedance amplifier, specially designed, which increases data acquisition sensitivity by a gain approximate to 1100 and does not introduce any significant distortion of input signal. By time integration of current intensity, an amount of charge as small as 2.7 x 10(-2) pC can be detected for photopeak events. (C) 2012 American Institute of Physics.

Abstract
In this paper a very sensitive ion collection device, for diagnostic of laser ablated-target plasma, is described. It allows for reducing down to few microvolts the signal threshold at digital scope input. A standard ion collector is coupled to a transimpedance amplifier, specially designed, which increases data acquisition sensitivity by a gain approximate to 1100 and does not introduce any significant distortion of input signal. By time integration of current intensity, an amount of charge as small as 2.7 x 10(-2) pC can be detected for photopeak events. (C) 2012 American Institute of Physics.
