Summary and outlook of the international workshop on aging phenomena in gaseous detectors (DESY, Hamburg, October 2001)

Abstract

High Energy Physics experiments are currently entering a new era which requires the operation of gaseous particle detectors at unprecedented high rates and integrated particle fluxes. Full functionality of such detectors over the lifetime of an experiment in a harsh radiation environment is of prime concern to the involved experimenters. New classes of gaseous detectors such as large-scale straw-type detectors, Micro-pattern Gas Detectors and related detector types with their own specific aging effects have evolved since the first workshop on wire chamber aging was held at LBL, Berkeley in 1986. In light of these developments and as detector aging is a notoriously complex field, the goal of the workshop was to provide a forum for interested experimentalists to review the progress in understanding of aging effects and to exchange recent experiences.A brief summary of the main results and experiences reported at the 2001 workshop is presented, with the goal of providing a systematic review of aging effects in state-of-the-art and future gaseous detectors.

New developments and future perspectives of gaseous detectors

“…A detailed discussion of aging phenomena is beyond the scope of this paper. The achievements of past R&D projects are summarized in [68,69,70,71], the most recent developments in radiation hardness research with state-of-the-art gaseous detectors are reviewed in [72,73,74]. Detailed studies of micro-pattern GEM and Micromegas concepts have revealed that they might be even less vulnerable to radiation-induced performance degradation in harsh radiation environments than standard silicon microstrip detectors.…”

Radiation Damage and Long-Term Aging in Gas Detectors

“…The achievements of past R&D projects in gas detectors are excellently summarized in [1][2][3][4], new developments in the radiation damage research have been reviewed at the 'International workshop on Aging Phenomena in Gaseous Detectors' held at DESY, Hamburg in October, 2001 [5,6]. A great effort has resulted in the optimization and construction of large systems of gas detectors for intense hadron beams, depending on the need for the best spatial resolution (MPGD), best timing resolution for trigger (Resistive Plate Chambers (RPC), MPGD), high-rate tracking and particle identification (straw-type detectors and multi-wire proportional chambers (MWPC)) and single photon detection (CsI-GEM photodetectors).…”

Aging effects in gas detectors

“…The knowledge accumulated since the first workshop was summarised at the second international workshop on "Aging Phenomena in Gaseous detectors" held at DESY in the year 2001 [7]. The present article is largely based on results reported at this workshop and on several excellent comprehensive reviews of this subject [8][9][10][11]. Measured and expected particle rates as a function of radial distance to the beam axis for various experimental conditions.…”
