“…To lower the resistivity, we used Boron ion implantation as suggested in Refs. [2,5,7). By implanting 10 16 ions/cm 2 at 150 keV with an average range of0.28 pm in Alumina, we measured the surface resistivity to be about 1.6x10 16 0/D (see Table 1).…”

“…Glass substrates have been widely used for making MSGCs [1,[3][4][5][6][8][9][10][11][12][13].Glass has a very smooth surface and is suitable for photolithography processing. Recent work has shown that electronic conduction in the glass is responsible for achieving stable operation and high rate capability for a MSGC [9][10][11].…”

“…INTRODUCTION The introduction of the Microstrip Gas Chamber (MSGC) by A. Oed [1] has attracted a great deal of attention over the last five years. Many efforts [2][3][4][5][6][7][8][9][10][11][12][13] have demonstrated that this new gas detector has much improved performance over a conventional Multi-Wire Proportional Chamber (MWPC). Its energy resolution, spatial resolution, rate capability radiation resistance, and low cost .…”

“…Applying proper potentials to the electrodes, an electric field builds up such that electrons released in the drift space are collected and multiplied reaching the anodes. MSGCs have very promising features: -proportional gains over 10 4 [7]; -position accuracy around 30 µm rms [8]; -rate capability above 10 6 mm -2 s -1 [9]; -energy resolution ~11% fwhm for 5.9 keV X-rays [10]; -moderate costs, typically around 200 $ for an active substrate area 10x10 cm 2 .…”

Many laboratories world-wide have contributed to the R&D project RD-28 at CERN (development of high rate micro-strip gas chambers). Various aspects of the design and use of the detector have been studied, in particular those connected with long-term operation in a high radiation flux. This paper summarizes some major outcomes of the research: the development of controlled resistivity substrates, the studies of pollution-induced ageing processes, the effects of substrate and metallization on performance, the operating characteristics in beam conditions.

“…Microstrip and microgap gaseous detectors operated at high pressure have been considered for the development of 2D devices with low granularity, efficient in an energy range of up to 25 keV in detectors for medical applications and synchrotron radiation [1][2][3]. We have reported that even when using microgaps with narrow anodes (4 m) the safe maximum gain at 6 bar at high rates is low (under 200) [4] and that in order to be used in practical detectors these devices should be used with a preamplification structure such as the recently developed gas electron multiplier (GEM) [5].…”

One of the main drawbacks of the use of microgap structures when used at high pressure (6 bar) at high count rates (&10 s\ mm\) is the limited maximum safe gain at which they can be operated. The use of a preamplification device such as the GEM (gas electron multiplier) can overcome this limitation; however, secondary space charge effects due to charge accumulation at the non-metallic surfaces cannot be neglected and should be minimised. These positive charges are due to the intrinsic multiplication of the GEM device and also to the drift of ions from the anode of the main detector. In this study we present data on the variation of the positive ion collection by the drift electrode versus drift field at several pressures up to 6 bar using a Kr-CO mixture. Data were collected with microgaps having several anode and insulator widths. The influence of the drift field in the pulse rise time is also considered.
