Description
Micro-Pattern Gaseous Detectors (MPGDs) have established themselves as vital components in modern particle physics, offering high spatial resolution, excellent rate capability, and flexible design topologies. However, transitioning MPGD concepts into reliable, large-scale experimental implementations requires addressing critical operational challenges and production constraints.
This talk provides an integrated overview of the existing MPGDs. We begin by examining representative MPGD designs and their intrinsic operational features. To ensure long-term stability under intense particle flux, we review spark protection strategies, focusing on resistive film implementations, resistive structures, and HV segmentation techniques designed to limit discharge energy and avoid catastrophic damage.
Furthermore, we address the often-overlooked threat of humidity and moisture absorption in hygroscopic substrates. To mitigate contamination during assembly and recovery post-manufacture, electrical cleaning and high-voltage burn-in/conditioning protocols are presented as effective methods for eliminating micro-debris and dark currents. Finally, we discuss industrial transfer and mass production considerations, to satisfy possibly next-generation collider experiments.
