Before starting a beamtime at FLASH the users have to consider several options regarding the control and data acquisition system where the users are supported by the controls group.


Table of Contents



The FLASH accelerator, beamlines and experiments are using the Distributed Object Oriented Control System ( DOOCS). Beamline and experiment devices are mainly operated via graphical user interfaces created with the Java DOOCS Data Display ( jddd) by the FLASH team or the users themself. Further it is provided a DOOCS client API in Java, Python, Matlab, C or C++ to the users to write own software for data access, online data or device control. User-provided devices can be run in parallel or can be implemented in DOOCS. For each beamline and accelerator is a dedicated electronic logbook available in which jddd and other software can print directly.
