Abstract:In order to satisfy the requirement of the soft X ray energy measurement, a gated integrator which integrates the output current to X ray detectors in a limited time has been developed.The tests with signal sources show that the efficient gate width in which the current is integrated is about 7.8ns and the integral nonlinearity is less than 3%. The maximum error between the integral results of the gated integrator and of oscilloscope is less than 5% of the scale range of the gated integrator.
Keywords:ICF  soft X  ray  energy  measurement  gated integrator
