Jakub Wozniak

Software Engineer, CERN

Jakub is a Senior Software Engineer specialising in Java Controls Systems working in the Beams department at CERN in Geneva, Switzerland. Currently he is the Project Lead for the CERN Accelerator Logging System (CALS) that is used to capture, persist and make available the readings from tens of thousands of devices that form CERN’s particle accelerator complex. This data is used to understand the current and historical state of the infrastructure, to tune systems and improve the quality of the beams, to take strategic managerial decisions, and to prepare scientific papers. Since 2003, the system is widely used by more than 1000 people from around CERN. Since 2014 Jakub has been passionately steering the evolution of CALS from Oracle towards Big Data, Hadoop and Apache Spark. Jakub was previously leading the design of other systems important to Beam Controls among which are the Fixed Display Framework (FDF) and the Software Interlock System (SIS). Both the FDF and the SIS are key tools used by the Operations team to understand conditions of all-important sub-systems and automatically permitting or interlocking the beam production for the Large Hadron Collider (LHC), the Super Proton Synchrotron (SPS) and the Injector Complex. For more than 3 years he has also been appointed as a Proton Synchrotron (PS) supervisor – managing the Operations team and assuring the coordination of beam delivery to the up-stream accelerators (the SPS and LHC) and the PS experimental facilities. Jakub holds a Masters (MSc) in Software Engineering obtained with honours from Warsaw University of Technology.

The Next CERN Accelerator Logging Service—A Road to Big Data

The LHC performance has reached new heights, in-turn the amount of data produced by the underlying infrastructure and observation systems has increased by an order of magnitude putting unprecedented load on the current data Logging… Read more

The Architecture of the Next CERN Accelerator Logging Service

The Next Accelerator Logging Service (NXCALS) is a new Big Data project at CERN aiming to replace the existing Oracle-based service. The main purpose of the system is to store and present Controls/Infrastructure related data… Read more
