A Novel Approach to Build a Gated Integrator for HighResolution Energy Spectroscopy Systems
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 2
Abstract
A gated integrator (GI) is to solve the ballistic deficit problem by integrating the signal until all the charge is collected from the detector. With the development of radioactive ion beam physics, heavy-charged particles like carbon ions have been applied to the treatment of deep-seated inoperable tumors in the therapy terminal of the Heavy ion Research Facility in Lanzhou (HIRFL) located at the Institute of Modern Physics (IMP), Chinese Academy of Sciences (CAS). An accurate low current measurement circuit was developed to control the beam current at 1pA range. The circuit consisted of a low current high sensitivity I/V converter and GI in an energy spectroscopy. This paper will show a new switch configuration made by transmission gates circuit which is used to prevent leakage current and at the same time used as a novel technique to compensate a charge injection in the reset switch.
