Advances in imaging THGEM-based detectors

We report on recent measurements with Thick GEM-like (THGEM)—based imaging detectors. The THGEM is a robust gaseous electron multiplier similar to GEM but with larger dimensions. It has high electron multiplication, of 10 5 and 10 7 in single- and double-THGEM structure, respectively, fast signals and ∼ 10 MHz / mm 2 counting rate capability. It can be produced in any shape and over large area. In view of many possible applications of THGEM-based imaging detectors, in particle physics and beyond, we have recently studied the localization properties of a 2D 10 × 10 cm 2 detector. The results of these studies are presented.
