TZPGcalc
Interactive jupyter notebook widget to calculate transmission zone plate grating (TZPG, also known as beam splitting off-axis zone plate) beam sizes and position at the sample and detector planes for the SCS instrument.
The so far implemented features are:
- calculates geometric beam propagation for diffracted beams by the grating (1st, -1st and 0th order)
- calculates geometric beam propagation for focused and unfocused beams by the off-axis zone plate (1st, 0th order)
- calculates beam sizes and position for 2 energies
- calculates sample position (membrane size and pitch) as well as etched facets
- calculates position of the DSSC module 15 as well as filter bar position
- calculates focal length change due to the KBS
- calculates beam focusing by KBS for the zone plate 0th order
- calculates beam and sample shape for sample at non-normal incidence angle
