ESS_butterfly
ComponentCOMPONENT Source = ESS_butterfly(sector="N",beamline=5,Lmin=0.1,Lmax=20,dist=2, cold_frac=0.5, yheight=0.03,focus_xw=0.1, focus_yh=0.1)The example instrument used to generate the below benchmarking data is available here. The component and all necessary bits will be released mid September 2016 as
The following features are worth highlighting:
ESS_butterfly.comp
at GitHub.
We expect to release an MCNP-event-based source model later in 2016, and possibly also new set of brilliance functions for ESS_butterfly.comp. These are expected to include more realistic brilliances in terms of variation across sectors and potentially also performance losses due to engineering reality.
Name | Unit | Description | Default |
---|---|---|---|
sector | str | Defines the 'sector' of your instrument position. Valid values are "N","S","E" and "W" | "N" |
beamline | 1 | Defines the 'beamline number' of your instrument position. Valid values are 1..10 or 1..11 depending on sector | 1 |
yheight | m | Defines the moderator height. Valid values are 0.03 m and 0.06 m | 0.03 |
cold_frac | 1 | Defines the statistical fraction of events emitted from the cold part of the moderator | 0.5 |
target_index | 1 | Relative index of component to focus at, e.g. next is +1 this is used to compute 'dist' automatically. | 0 |
dist | m | Distance from origin to focusing rectangle; at (0,0,dist) - alternatively use target_index | 0 |
focus_xw | m | Width of focusing rectangle | 0 |
focus_yh | m | Height of focusing rectangle | 0 |
c_performance | 1 | Cold brilliance scalar performance multiplicator c_performance > 0 | 1 |
t_performance | 1 | Thermal brilliance scalar performance multiplicator t_performance > 0 | 1 |
Lmin | AA | Minimum wavelength simulated | |
Lmax | AA | Maximum wavelength simulated | |
tmax_multiplier | 1 | Defined maximum emission time at moderator, tmax= tmax_multiplier * ESS_PULSE_DURATION. | 3 |
n_pulses | 1 | Number of pulses simulated. 0 and 1 creates one pulse. | 1 |
acc_power | MW | Accelerator power in MW | 5 |
