Geostationary Coastal and Air Pollution Events (GeoCAPE) Wide Angle Spectrometer (WAS)

The GeoCAPE Wide Angle Spectrometer (WAS) Study was a revisit of the COEDI Study from 2012. The customer primary goals were to keep mass, volume and cost to a minimum while meeting the science objectives and maximizing flight opportunities by fitting on the largest number of GEO accommodations possible. Riding on a commercial GEO satellite minimizes total mission costs. For this study, it is desired to increase the coverage rate,km2min, while maintaining ground sample size, 375m, and spectral resolution, 0.4-0.5nm native resolution. To be able to do this, the IFOV was significantly increased, hence the wide angle moniker. The field of view for COEDI was +0.6 degrees or (2048) 375m ground pixels. The WAS Threshold (the IDL study baseline design) is +2.4 degrees IDL study baseline design) is +2.4 degrees

Laboratory angular and momentum distributions of protons, kaons and pions from photoproduction on hydrogen at energies up to 5.8 GeV

Information is presented on the laboratory angular and momentum distributions of protons, π + and π − mesons and K S 0 mesons produced by a photon beam with an approximate bremsstrahlung spectrum on hydrogen. The data may be useful for designing secondary pion and kaon beams, for planning experiments and for background estimates at electron accelerators
