Design and Test of a Beam-Pulsing Electronics System for Low-Energy Positron Lifetime Spectroscopy

摘要：

An apparatus of low-energy positron lifetime spectroscopy (LEPLS) using beam pulsing technique has recently been established in the Laboratory of Nuclear Solid State Physics (LNSSP) in the University of Science and Technology of China (USTC). In order to compress the DC beam into pulse width of 150-200ps (FWHM) at the target,a beam-pulsing electronics system,required by the pulsing system of LEPLS,is capable of generating three signals,one is the pulse signal at 50 MHz with amplitude greater than 5V,edge time less than 2ns and pulse width about 7ns. and others are two sine signals at 50MHz and 200MHz with amplitude greater than 2V. The design of the beampulsing electronics system with test results is presented in this article. The beam-pulsing electronics system design,shown in the test results,meets all requirements of LEPLS.
