摘要: Abstract The article describes a multistop TDC with resolution of 1 ns designed for time-of-flight mass spectrometry (maximum 128 μs) in heavy ion induced desorption experiments. dead time the device is 80 ns. An optional circuit random rejection stop signals allows observation second two masses desorbed simultaneously, whose flight differs from first by less than
