Welcome to the Hercules 2022 Oasys tutorial written by Manuel Sanchez del Rio and Juan Reyes Herrera.

The aim of this course is to learn the following:

- Calculate main characteristics of synchrotron source (Bending magnets and Insertion devices).

Calculate the heat-load on different beamline components.

Simulating beamline optics by ray-tracing to obtain main parameters of the beam, e. g., size and divergence, energy resolution, intensity/flux.

Understand basic principles of X-ray optics: Mirrors and Crystals.

Basic concepts about coherence.

And it is split into four sections: 

1. Introduction

2. Power Transport

3. Photon Transport

4. Coherence Transport

Before going to the content, it is important to explain that you can use OASYS in two ways:

1. Install Oasys on your own laptop. Follow the instructions in the following links: 
   Mac OS        Windows OS        Linux OS        [Docker
   

](https://github.com/oasys-kit/oasys-installation-scripts/wiki/Use-Docker-Oasys-container)
This course needs the installation of the ESRF add-on in OASYS. Open OASYS and follow the "install as user" instructionshere.

1. Login and get an account in: https://vuo.elettra.eu
   Once logged in (please use Chrome), you have to go to Virtual Laboratory and click on My applications , then click on [Start] of _ SCITOOLBOX _ application, and then click [next] and wait a few minutes (only the first time).
   When your session is open, open OASYS as shown below:
   
   

It is very important to let us know if you want to use this second option in order to give you the necessary permissions to use the app.
