Performance Studies of Bulk Micromegas of Different Design Parameters
The present work involves the comparison of various bulk Micromegas detectors
having different design parameters. Six detectors with amplification gaps of
and mesh hole pitch of were tested at room temperature and normal gas pressure. Two
setups were built to evaluate the effect of the variation of the amplification
gap and mesh hole pitch on different detector characteristics. The gain, energy
resolution and electron transmission of these Micromegas detectors were
measured in Argon-Isobutane (90:10) gas mixture while the measurements of the
ion backflow were carried out in P10 gas. These measured characteristics have
been compared in detail to the numerical simulations using the Garfield
framework that combines packages such as neBEM, Magboltz and Heed.Comment: arXiv admin note: text overlap with arXiv:1605.0289
