As one of the promising Micro-pattern Gaseous Detectors (MPGDs), Thick
Gaseous Electron Multiplier (THGEM) is attractive due to its high gain, robust
and low cost. In order to promote its applications, continuous efforts had been
making to improve the performances and production technologies of THGEMs.
The advancements in both development and applications are presented,
including high spatial resolution, new substrates, new structures, big area,
neutron detection, CCD-based optical readout, and Digital Hadron Calorimeter
(DHCAL).
