Detecteur multipointes a focalisation cathodique

Detection & imaging with Leak Microstructures

“…This last version of LMs matrix presents some innovations with regard to that described in ref. [7][8][9][10]: some experimental measures and various simulations have shown that, in order to avoid the imaging dead zones, the pitch of the needles has to be 3 mm or less.…”

“…Some years ago we introduced a new kind of gaseous detector based on needles (or points) used as anodes, that is the Leak Microstructures (LM) [1][2][3][4][5][6][7][8]. It belongs to the family of gaseous detectors based on points as anodes such the "Detecteur Multipointes a Focalisation Cathodique" [9][10][11], and the "Pin Detector" [12,13]. The LM detector is different from the above detectors for the geometry and for some properties.…”

Contribution à l'étude des détecteurs multipointes à focalisation cathodique

“…Chaque événement ionisant déclenche un processus saturé. L'amplitude croît linéairement avec la tension [1]. Le spectre en amplitude ne dépend plus du nombre de charges initiales.…”

“…Introduction. -La première étude concernant les compteurs multipointes à focalisation cathodique [1] rassemblait des tests démontrant la faisabilité d'un détecteur multipointes composé d'un grand nombre de cellules détectrices juxtaposées.…”

Performance study of a micro-pattern gas detector: leak microstructure

“…The micro-pattern gas detectors (MPGD) have experienced a flourishing development in past decades. Many kinds of micro-structure detectors have been put forward and investigated, among which the hole structures (like GEM,THick GEM) [1][2][3] and micro mesh structure (MICROMEGAS) [4] achieved great success.The concept of micro-point (or pin) geometry came forth in the 1980s [5][6][7]. A typical example is the leak microstructure (LM) detector, which has been proposed since 1997 [8].…”
