Electron resonance scattering from mercury
1977
The differential cross section and the spin polarisation of electrons scattered elastically from mercury have been measured as a function of collision energy in the range 4.0 to 6.0 eV for several selected scattering angles. The observed data can be understood if one assumes that resonances are formed at 4.55 eV in the 2S1/2, at 4.71 eV in the 2D3/2 and at 4.94 eV and 5.51 eV respectively in the 2D5/2 scattering state.
Performance Analysis of the SO/PHI Software Framework for On-board Data Reduction
2019
The Polarimetric and Helioseismic Imager (PHI) is the first deep-space solar spectropolarimeter, on-board the Solar Orbiter (SO) space mission. It faces: stringent requirements on science data accuracy, a dynamic environment, and severe limitations on telemetry volume. SO/PHI overcomes these restrictions through on-board instrument calibration and science data reduction, using dedicated firmware in FPGAs. This contribution analyses the accuracy of a data processing pipeline by comparing the results obtained with SO/PHI hardware to a reference from a ground computer. The results show that for the analyzed pipeline the error introduced by the firmware implementation is well below the requirem…
