Wide-band current preamplifier for conductance measurements with large input capacitance
Wide-band current preamplifier conductance measurements large input capacitance
2012/4/20
A wide-band current preamplifier based on a composite operational amplifier is proposed. It has been shown that the bandwidth of the preamplifier can be significantly increased by enhancing the effect...
Companding technique for high dynamic range measurements using gafchromic films
Companding technique high dynamic gafchromic films
2011/8/5
Abstract: We propose a methodology to perform dose measurements using gafchromic films which can span several decades of dose levels. The technique is based on a rescaling approach using different fil...
