Scientific Reviews: Microstrip Gas Chambers (MSGC) for Future Neutron Instrumentation

Novel electron and photon recording concepts in noble-liquid detectors

“…Such potential charging up is not expected under the proposed conditions of EL in liquid with an optional small (< 10) charge gain. The active area of MSGC detectors reaches 240 × 240 mm 2 [62]. For a MSP review see [61].…”

Neutron detectors for the ESS diffractometers

“…A detector based on the MSGC-technology and a curved-MWPC similar to those used at the D20 [35] or D1B instruments [27], respectively, also meet the requirements in terms of pixel size and count rate capability. However, both technologies would require a significant amount of R&D and engineering work in order to increase the angular coverage in the vertical direction, which is now limited to 40 [34] and 20 cm [64], respectively. But, more importantly, the unclear unavailability of the 3 He gas in the future represents a high risk for the ESS science program [65,66].…”

“…Moreover, the required sensitive area does not exceed 1 m 2 per detector. Thus, the need for high-efficiency, high-granularity SANS detectors could, in principle, be satisfied with the existing technologies such as the medium-size 3 He-filled MWPCs similar to those operational at the REFSANS instrument at MLZ Garching [68], the SANS beamline at the BNC [69] or the D16 instrument at ILL [30,31], a MSGC-based detector [34] or even square-shaped position sensitive-tubes (PSD) in a monoblock design [70].…”

“…Another development that led to several operational detectors for use at high-intensity neutron sources is the Microstrip Gas Chamber (MSGC) [32], which exploits the micro-strip technology [33]. MSGC-based detectors are installed today at the D4 and D20 instruments [34,35] at ILL. The D20 detector can reach a count rate of 20 kHz per 3.2 • -cell at 10% deadtime and provide an intrinsic resolution of 3 mm [35].…”

Позиционно-чувствительные детекторы тепловых и холодных нейтронов с газовым конвертором -=SUP=-3-=/SUP=--=SUB=-2-=/SUB=-He (oбзор)

“…В ILL создавались первоклассные дифракционные приборы с позиционно-чувствительными детекторами как на MWPC, так и на MSGC. За 20 лет создано более десяти дифракционных приборов, построенных на MSGC [20,[30][31][32][33], которые успешно работают до настоящего времени. В качестве примера приведем дифрактометр D20.…”
