Compact cosmic ray detector for unattended atmospheric ionisation monitoring
ثبت نشده
چکیده
Two vertical cosmic ray telescopes for atmospheric cosmic ray ionisation event detection are compared. Counter A, designed for low power remote use, was deployed in the Welsh mountains; its event rate increased with altitude as expected from atmospheric cosmic ray absorption. Independently, Counter B’s event rate was found to vary with incoming particle acceptance angle. Simultaneous co-located comparison of both telescopes exposed to atmospheric ionisation showed a linear relationship between their event rates.

متن کاملSolar modulation in surface atmospheric electricity
The solar wind modulates the flux of galactic cosmic rays impinging on Earth inversely with solar activity. Cosmic ray ionisation is the major source of air’s electrical conductivity over the oceans and well above the continents. Differential solar modulation of the cosmic ray energy spectrum modifies the cosmic ray ionisation at different latitudes, varying the total atmospheric columnar condu...
متن کاملRadiative effects of tropospheric ionisation
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Despite the increasing evidence that cosmic ray variations may influence clouds and climate, there has been little discussion of the direct radiative effects of atmospheric ionisation. Laboratory experiments show that hydrated molecular cluster-ions, form...
متن کاملVertical profile measurements of lower troposphere ionisation
Vertical soundings of the atmospheric ion production rate have been obtained from Geiger counters integrated with conventional meteorological radiosondes. In launches made from Reading (UK) during 2013–2014, the Regener–Pfotzer ionisation maximum was at an altitude equivalent to a pressure of (63.172.4) hPa, or, expressed in terms of the local air density, (0.10170.005) kg m . The measured ioni...
متن کاملScanning Lidar Based Atmospheric Monitoring for Fluorescence Detectors of Cosmic Showers
Measurements of the cosmic-ray air-shower fluorescence at extreme energies require precise knowledge of atmospheric conditions. The absolute calibration of the cosmic-ray energy depends on the absorption of fluorescence light between its origin and point of its detection. To reconstruct basic atmospheric parameters we review a novel analysis method based on twoand multi-angle measurements perfo...
