Neutron Monitor Design Improvements

Temporal variation of 7Be concentrations in atmosphere for 8y from 2000 at Yamagata, Japan: solar influence on the 7Be time series

“…Fig. 3 shows the 7 Be concentrations, SSN, and neutron intensities (counts h À1 ) observed using the NM64-type proportional counter (Stoker et al, 2000) on the ground at Thule. The 7 Be concentration profile shows an increase in the following three stages: 1) a slow decrease from 2000 to 2002, 2) a hump from 2003 to 2005, and 3) a saturated top from 2006 to 2007.…”

Soft-errors induced by terrestrial neutrons and natural alpha-particle emitters in advanced memory circuits at ground level

“…A Canberra electronic detection chain composed of three charge amplifiers model ACHNP97 and a high voltage source 3200D) was chosen in complement to a Keithley KUSB3116 acquisition module for interfacing the neutron monitor with the control PC. The design and the construction of the PdBNM followed the recommendations published in [19,20] for the optimization of the apparatus response. Fig.…”

Assessment of spectral and angular characteristics of sub-GLE events using the global neutron monitor network

“…Subsequently, the design of NM was considerably optimized leading to an increase of the NM counting rate (Hatton and Carmichael, 1964;Hatton, 1971). This second generation of the NM design is known as NM64(for details see Carmichael H. (1968);Hatton (1971); Stoker et al (2000) and references therein). Mini NMs were recently introduced (Krüger and Moraal, 2013;Krüger et al, 2015).…”
