Abstract
We show that the addition of small amounts of sulphur hexafluoride, SF 6, to the present ATLAS baseline gas mixture C2H2F4/C4H10 has a very s trong effect in suppressing the avalanche-to-streamer transition. An R PC of 50 x 50 cm(2) area, 2 mm gas gap was operated in pure avalanche, streamer-free mode in a voltage range of about 1 kV. The results of t he test suggest that the observed fast signal could be interpreted as the sum of contributions of a number of primary saturated avalanches. (C) 1998 Elsevier Science B.V.
