TMM: Triple Micro-Mesh gaseous structure with ultralow ion backflow for gaseous photon detectors
Gaseous photomultiplier tubes sensitive to visible light and based on micro-pattern gaseous detectors have been widely investigated due to their wide range of potential applications. This study presents a novel triple micro-mesh gaseous structure (TMM) specifically designed for this purpose, featuring ultralow ion backflow (IBF). Prototypes of the TMM were manufactured and characterized with both an X-ray source and an ultraviolet laser, and the results demonstrated an unprecedented IBF ratio of 3 × 10−5 at gas gains exceeding 1 × 105, indicating a promising capability of TMMs for visible light detection.
期刊介绍：
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
