Vacuum Controls for ALBA – VACCA

What is it?

The beam-life, i.e. the time that the beam can be maintained in the storage ring, is inversely proportional to molecular density, i.e. pressure, inside the ring. That is why a synchrotron like ALBA needs Ultra-High-Vacuum with a range of pressure below 10-8 mbar.

The Vacuum Control System for ALBA consists in a set of hardware devices and control software to monitor and control them. Physical devices involve vacuum devices (ion pumps, gauges or valves) and Vacuum Controllers (VarianDUAL, MKS 937 or B&R PLC).

User Applications

 The control of all ALBA accelerators vacuum systems (LI,LT,BO,BT,SR) have been integrated in a single application that allows fast access to general views of each system and fast searchs to each individual hardware component. Devices from close-related subsystems (EPS, FE) are also available in the application tree.

 The general views are based on synoptics and pressure profiles. The detailed view allows plotting of vacuum variables vs. any other tango attribute from the accelerator control system. The plotting tools allow to plot both actual and archived values.

 From the main Vacca application it's also possible to open synoptic views of ALBA systems, showing the position of each pressure reading from the system and the in-situ hardware status.
