### Preparing a new input deck for SwissFEL

#### Step 1 - Preparing the input distribution
Starting with an Asta-output distribution, several adjustments can be applied.
1. Converting Astra output to SDDS format for the import in Elegant
2. Apply missing wakefields for SINSB01 and SINSB02
3. Optional - Cutting the tail to avoid particles with a strong longitudinal offsets, which can render the space charge calculation in Elegant difficult.
4. Analyse projected and slice parameters to generate a reference report
5. Optional - Increase or decrease particle number based on the beam slice parameters

#### Step 2 - Configure Longitudinal Compression
Run Longitudinal Tracker to configure R56 and RF phases. For the tracking import the generated distribution from Step 1. Export the settings for the RF settings.

#### Step 3 - Configure Optics
Run OpticsTool for a given beamline. Import the beam report from Step 1 and the RF settings from Step 2. Match the lattice and save the settings.

#### Step 4 - Geenrate Elegant Files
Run ElegantTool to import distribution and optics settings to generate the elegant input file and lattice.
