The Alba control system * is based on Sardana **, a software package implemented in Python, built on top of Tango *** and oriented to beamline and accelerator control and data acquisition. Sardana provides an advanced scan framework, which is commonly used in all the beamlines of Alba as well as other institutes. This framework provides standard macros and comprises various scanning modes: step, hybrid and software-continuous, however no hardware-continuous. The continuous scans speed up the data acquisition, making it a great asset for most experiments and due to time constraints, mandatory for a few of them. A continuous scan has been developed and installed in three beamlines where it reduced the time overheads of the step scans. Furthermore it could be easily adapted to any other experiment and will be used as a base for extending Sardana scan framework with the generic continuous scan capabilities. This article describes requirements, plan and implementation of the project as well as its results and possible improvements.

This paper describes the model, objectives and implementation of a generic data acquisition structure for an experimental station, which integrates the hardware and software synchronization of motors, detectors, shutters and in general any experimental channel or events related with the experiment. The implementation involves the management of hardware triggers, which can be derived from time, position of encoders or even events from the particle accelerator, combined with timestamps for guaranteeing the correct integration of software triggered or slow channels. The infrastructure requires a complex management of buffers of different sources, centralized and distributed, including interpolation procedures. ALBA uses Sardana built on TANGO as the generic control system, which provides the abstraction and communication with the hardware, and a complete macro edition and execution environment.
