R&D efforts are ongoing to develop the Cylindrical Micromegas Barrel Layer (CyMBaL) for central region of ePIC detector, first experiment at future Electron Ion Collider (EIC). The detectors will be part a multi-technology tracker located inside 1.7 T solenoid, bringing stringent limits on space. Constraints momentum reconstruction performances also impose low-material budget in order not degrade measurements placed behind. As such, light resistive equipped with 2D readout is needed. goal...
Two different depleted monolithic CMOS active pixel sensor (DMAPS) prototypes with a fully synchronous column-drain read-out architecture were designed and tested: LF-Monopix TJ-Monopix. These chips are part of R&D effort towards suitable implementation DMAPS for the HL-LHC ATLAS Inner Tracker. was developed using 150nm process on highly resistive substrate (>2 k$Ω\,$cm), while TJ-Monopix fabricated modified 180 nm 1 k$Ω\,$cm epi-layer depletion.

Monolithic Active Pixel Sensors (MAPS) have been developed since the late 1990s employing silicon substrate with a thin epitaxial layer in which deposited charge is collected by disordered diffusion rather than drift an electric field. As consequence signal small and slow, radiation tolerance below requirements for LHC experiments factors of 100 to 1000. We fully depleted (D)MAPS pixel sensors 150 nm CMOS technology using high resistivity as well biasing voltage. The development has carried...

Implementing such device detector module will result lower production cost and material budget compared to presently used hybrid designs. In this paper chip...
New large-size Micromegas detectors are being developed for the future physics program of COMPASS experiment at CERN.

We have developed highly interleaved zigzag-shaped electrodes for collecting charge on the readout plane of various micropattern gaseous detectors (MPGDs), including gas electron multiplier (GEM) and micromega detectors. An optimized zigzag pad (or strip) anode can greatly enhance sharing among neighboring pads compared to traditional straight strip or rectangular designs as a result deliver excellent position resolution with minimal channel count, while exhibiting virtually uniform response...

This document illustrates the technical layout and expected performance of a Time Projection Chamber as central tracking system PANDA experiment. The detector is based on continuously operating TPC with Gas Electron Multiplier (GEM) amplification.
Due to their simplicity and versatility of design, straight strip or rectangular pad anode structures are frequently used with micropattern gas detectors (MPGDs) reconstruct high-precision space points for various tracking applications. The particle impact point is typically determined by interpolating the charge collected several neighboring strips. However, effectively extract inherent positional information, lateral spacing strips must be comparable preferably smaller than full extent...
