Optical Readout Studies of the Thick-COBRA Gaseous Detector / Garcia, F. (Helsinki U.) ; Brunbauer, F.M. (CERN) ; Lisowska, M. (CERN ; Wroclaw Tech. U.) ; Müller, H. (CERN) ; Oliveri, E. (CERN) ; Pfeiffer, D. (CERN ; ESS, Lund ; Milan Bicocca U.) ; Ropelewski, L. (CERN) ; Samarati, J. (CERN ; ESS, Lund) ; Sauli, F. (CERN) ; Scharenberg, L. (CERN ; Bonn U.) et al.
The performance of a Thick-COBRA (THCOBRA) gaseous detector is studied using an optical readout technique. The operation principle of this device is described, highlighting its operation in a gas mixture of Ar/CF4 (80/20%) for visible scintillation light emission. [...]

Simulation of gain stability of THGEM gas-avalanche particle detectors / Correia, P.M.M. (Aveiro U.) ; Pitt, M. (Weizmann Inst.) ; Azevedo, C.D.R. (Aveiro U.) ; Breskin, A. (Weizmann Inst.) ; Bressler, S. (Weizmann Inst.) ; Oliveira, C.A.B. (Aveiro U.) ; Silva, A.L.M. (Aveiro U.) ; Veenhof, R. (CERN) ; Veloso, J.F.C.A. (Aveiro U.)
Charging-up processes affecting gain stability in Thick Gas Electron Multipliers (THGEM) were studied with a dedicated simulation toolkit. Integrated with Garfield++, it provides an effective platform for systematic phenomenological studies of charging-up processes in MPGD detectors. [...]

THGEM gain calculations using Garfield++: solving discrepancies between simulation and experimental data / Azevedo, C.D.R. (Aveiro U.) ; Correia, P.M.M. (Aveiro U.) ; Carramate, L.F.N.D. (Aveiro U.) ; Silva, A.L.M. (Aveiro U.) ; Veloso, J.F.C.A. (Aveiro U.)
Discrepancies between the measured and simulated gain in Thick Micropatterned gaseous detectors (MPGD), namely THGEM, have been observed by several groups. In order to simulate the electron avalanches and the gain the community relies on the calculations performed in Garfield++, known to produce differences of 2 orders of magnitude in comparison to the experimental data for thick MPGDs.

Pressure effect in the X-ray intrinsic position resolution in noble gases and mixtures / Azevedo, C.D.R. (Aveiro U.) ; Gonzalez-Diaz, D. (CERN) ; Correia, P.M. (Aveiro U.) ; Biagi, S. (Uludag U.) ; Silva, A.L.M. (Aveiro U.) ; Carramate, L.F.N.D. (Aveiro U.) ; Veloso, J.F.C.A. (Aveiro U.)
A study of the gas pressure effect in the position resolution of an interacting X- or gamma-ray photon in a gas medium is performed. The intrinsic position resolution for pure noble gases (Argon and Xenon) and their mixtures with CO2 and CH4 were calculated for several gas pressures (1-10bar) and for photon energies between 5.4 and 60.0 keV, being possible to establish a linear match between the intrinsic position resolution and the inverse of the gas pressure in that energy range. [...]

Position resolution limits in pure noble gaseous detectors for X-ray energies from 1 to 60 keV / Azevedo, C D R ; Biagi, S ; Veenhof, R (CERN) ; Correia, P M ; Silva, A L M ; Carramate, L F N D ; Veloso, J F C A
The calculated position resolutions for X-ray photons (1–60 keV1–60 keV) in pure noble gases at atmospheric pressure are presented. In this work we show the influence of the atomic shells and the detector dimensions on the intrinsic position resolution of the used noble gas. [...]

X-ray imaging detector based on a position sensitive THCOBRA with resistive line / Silva, A L M (Aveiro U.) ; Azevedo, C D R (Aveiro U.) ; Carramate, L F N D (Aveiro U.) ; Lopes, T (Aveiro U.) ; Castro, I F (Aveiro U.) ; de Oliveira, R (CERN) ; Veloso, J F C A (Aveiro U.)

A dynamic method for charging-up calculations: the case of GEM / Correia, P.M.M. (Aveiro U.) ; Oliveira, C.A.B. (Aveiro U. ; LBL, Berkeley) ; Azevedo, C.D.R. (Aveiro U.) ; Silva, A.L.M. (Aveiro U.) ; Veenhof, R. (CERN ; Uludag U.) ; Varun Nemallapudi, Mythra (CERN) ; Veloso, J.F.C.A. (Aveiro U.) /CERN RD-51 Collaboration
The simulation of Micro Pattern Gaseous Detectors (MPGDs) signal response is an important and powerful tool for the design and optimization of such detectors. However, several attempts to simulate exactly the effective charge gain have not been completely successful. [...]
