We present results on THGEM operation at low gas pressures, in the range 0.5-50 Torr. Gaseous gain up to 10 5 was recorded at 10 Torr of Isobutane in a single multiplier element, with pulses rise-time in the few ns range. Cascaded operation of two THGEMs is reported, with similar total gain but at lower voltages on each element. The present work encompasses a large variety of THGEM geometries and includes electric-field distribution calculations and electron transport simulations. We discuss the operation mechanism and some possible applications of THGEMs at low gas pressures.

Advances in the technologies associated with position sensitive gaseous detectors especially featuring CsI as reflective photoconverters will be reviewed. These photodetectors represent the most effective solution for what concerns cost and performance in the case of large area Cherenkov imaging applications in relatively low rate (or low occupancy) high energy physics and astrophysics experiments. Moreover, they are the only choice when the Cherenkov detector is embedded in a magnetic field. Recently proposed single-photon MPGDs (Micro-Pattern-Gaseous Detectors) will be also discussed in view of the successful efforts so far made to extend their sensitivity to visible light. With some modifications, photosensitive gaseous detectors can also be used in the imaging of X-rays and particles.

“…Thick gaseous electron multiplier (THGEM) is one type of micro-pattern gaseous detector (MPGD) that provides some advantages for many applications, such as high gain, robustness, easy production and relatively low cost [1][2][3][4]. And these aspects are known as the shortcomings of the traditional gas electron multiplier (GEM).…”

Introduction THick Gaseous Electron Multiplier (THGEM) has many advantages while the moderate position resolution is regarded as the main inferiority comparing with the traditional GEM, so this limits the applications of THGEM, such as X-ray imaging and charge particle tracking. Materials and methods By improving the production techniques, THGEMs with smaller pitch and hole diameter can be made, i.e., 0.4 and 0.15 mm by mechanical drilling, and 0.3 and 0.1 mm by laser etching, respectively. Based on the new THGEMs, a two-dimensional imaging detector with 50×50mm sensitive area was developed for 0.1 ∼ 50 MeV low-energy electrons detection and reaching better than 100μm position resolution (sigma). At the same time, a set of front-end electronics was developed based on homemade ASIC chips, i.e., Charge Amplifier and Shaping Amplifier for GEM (CASAGEM), and applied successfully to the detector. Conclusion The X-ray and beam tests results indicate that both detector and Front End Electronics (FEE) worked well, and the position resolution achieved 74.9μm by using the charge center-of-gravity method. This indicates that the high-B Yu-Guang Xie
