# Intro to PSD

Measurement:
PSD data:
# PSD in Synrad/Molflow
# Extruding the target to create a box
The target is already pointing towards the source, so we extrude it by 300cm (it's at Z=200cm)
And we ge ta closed box:
Let's run the simulation and save the file.
# Inserting in Molflow
We simply open the original Synrad file:
Molflow can open Synrad geometries:
Then we "import" desorption (start the PSD conversion process):
Since we opened the Synrad file, we'll choose "Use current file":
And we'll imitate a simple curve by a simple equation:
Time is 1h (3600 seconds), the longer the system conditions, the better:
The facet advanced parameters show that it worked and give some diagnostic info:
# Run a simulation
We currently want to diagnose PSD, so we'll set sticking=1 on all facets:
The simulation looks more or less fine, particles come from where they should:
Turning on Hits view and zooming on the source, we can see that molecules are created at irradiation locations:
Let's, however, create a desorption counting texture to visualize desorption:
# Result
On linear texture scaling (Synrad vs Molflow):
Flux is "compressed":
Synrad simulations: several orders of magnitude if possible:
