Welcome to the ARGOS Laser Guide Star wiki pages

This wiki collects all the information related to the 2 ARGOS laser guide star systems.

It is written for the users and the engineers that have to operate and maintain the systems. You will find in this wiki all the informations about operating procedures, calibrations and configurations, maintenance and installation procedures. You will not find study and design documentation. You will find the commissioning diary.

There is a DX system and a SX system. Each of them is composed of:

• the LgswSystem (the wavefront sensor and dichroic)
• the LasSystem (the laser box)
• the LanSystem (the launch system)
• the CalUnitSystem
• the TipTiltSystem
• the VibrationSystem
• the WorkStation
