The upgrade of the ALICE TPC with GEMs and continuous readout
J. Adolfsson, M. Ahmed, S. Aiola +232
The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we des…
Characterization of a triple-GEM position sensitive detector for X-ray fluorescence imaging
Geovane G. A. de Souza, Hugo Natal da Luz
In this work we characterized a X-ray position sensitive gaseous detector based in a triple stack of gas electron multipliers (GEM). The readout circuit is divided in 256 strips fo…
XRF element localization with a triple GEM detector using resistive charge division
Geovane G. A. de Souza, Hugo Natal da Luz
In this work we show the operation and results of an X-ray fluorescence imaging system using a cascade of three gas electron multipliers (GEM) and a pinhole assembly. The detector…
Particle identification studies with a full-size 4-GEM prototype for the ALICE TPC upgrade
M. M. Aggarwal, Z. Ahammed, S. Aiola +177
A large Time Projection Chamber is the main device for tracking and charged-particle identification in the ALICE experiment at the CERN LHC. After the second long shutdown in 2019/…
Ion backflow studies with a triple-GEM stack with increasing hole pitch
H. Natal da Luz, P. Bhattacharya, L. A. S. Filho +1
Gas Electron Multipliers have undergone a very consistent development since their invention in 1997. Their production procedures have been tuned in such a way that nowadays it is p…
Gain characteristics of a 100 micrometer thick GEM in Krypton-CO2 mixtures
R. C. Roque, H. Natal da Luz, L. F. N. D. Carramate +3
The operation of a Micropattern Gaseous Detector (MPGD) comprising a cascade of two non-standard Gas Electron Multipliers (GEM) made from a 100 micrometer kapton foil was evaluated…
3D Simulation of Electron and Ion Transmission of GEM-based Detectors
Purba Bhattacharya, Bedangadas Mohanty, Supratik Mukhopadhyay +2
Time Projection Chamber (TPC) has been chosen as the main tracking system in several high-flux and high repetition rate experiments. These include on-going experiments such as ALIC…
Near-Intrinsic Energy Resolution for 30 to 662 keV Gamma Rays in a High Pressure Xenon Electroluminescent TPC
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
We present the design, data and results from the NEXT prototype for Double Beta and Dark Matter (NEXT-DBDM) detector, a high-pressure gaseous natural xenon electroluminescent time…
In-situ calibration of a PMT inside a scintillation detector by means of primary scintillation detection
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
We have investigated the possibility of calibrating the PMTs of scintillation detectors, using the primary scintillation produced by X-rays to induce single photoelectron response…
Initial results of NEXT-DEMO, a large-scale prototype of the NEXT-100 experiment
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
NEXT-DEMO is a large-scale prototype of the NEXT-100 detector, an electroluminescent time projection chamber that will search for the neutrinoless double beta decay of Xe-136 using…
The NEXT-100 experiment for neutrinoless double beta decay searches (Conceptual Design Report)
NEXT Collaboration, V. Álvarez, M. Ball +80
We propose an EASY (Electroluminescent ApparatuS of high Yield) and SOFT (Separated Optimized FuncTion) time-projection chamber for the NEXT experiment, that will search for neutri…
