18 Technology (TE) Department:
Novel septum magnet system design.

In the framework of the Consolidation project, studies are needed to prepare a concept design of a novel PS extraction septum magnet system. The system consists of a pulse generator, to be installed in a surface building, and its associated magnet in the accelerator tunnel. The pulse generator needs to be capable of supplying a very high and fast current pulse, while the novel eddy current septum magnet topology is to be designed robustly, and capable to produce the required field quality.
The study should address the problems related to the magnetic field distortions, feasibility of the fast pulse generator within the required precision and repeatability using power semi-conductors.  At present, the robustness of conventional septa is limited by vibrations and fatigue of the magnet coil.

Technology (TE) Department:
Configuration and operational monitoring platform for the LHC Quench Detection System

The Quench Detection System (QDS) is a vital component of the protection system for the superconducting magnet circuits of the LHC, protecting the magnets against overheating and damage in case of loss of their superconducting state. The QDS is deployed physically all around the accelerator and composed of a variety of different device types, all of which are fully integrated in the common controls stack of the LHC to allow for continuous control and monitoring. This implies a large and heterogeneous amount of hardware devices, all of which must be verified and re-validated following shutdown periods or interventions during the operation of the machine as the identification of faulty or misconfigured devices is crucial for the reliability and availability of the machine. Since the initial LHC commissioning and start-up, a variety of tools and applications has been developed and used to provide these functions which require significant maintenance to update.
The aim of the project is to provide a common and coherent framework for all these important operational tools, ensuring their continuous integration and availability with other systems throughout the different accelerator phases, from commissioning to operation and maintenance. Further objectives are the streamlining of communication channels of these tools for increased performance and operational monitoring. In this project, you will ensure integration of various existing Python and Java tools, developed by system experts, into a common Continuous Integration framework; consolidate practices and tools used for the reporting of the hardware devices status and configuration to the expert; extend the reporting tools to pre-operational checks.

Technology (TE) Department:
Automated commissioning of interlock systems within the Accelerator Testing Framework

Operational periods of CERNs accelerator complex are always followed by shutdown periods, ranging from a few days long technical stops to two years long shutdowns, during which vital maintenance operations are performed and the equipment systems are consolidated and upgraded. After any modification, in particular of protection related systems, dedicated commissioning periods allow for an in-depth validation by operation teams in collaboration with the equipment experts.
The commissioning of magnet circuits and their protection systems relies since 2012 on the Accelerator Testing framework (AccTesting), a Java Spring based framework that automates the scheduling, execution, tracking and analysis of more than ten thousand commissioning tests to validate the proper functioning of the 1800 magnet circuits of the LHC.
The aim of the project is the extension of automated commissioning to other vital LHC systems, at first for the magnet interlock systems (WIC) as well as the beam interlock (BIS) and safe machine parameter system (SMP) to facilitate the repetition of important commissioning steps as well for the operation crews. In a second step, automation will be extended to the LHC beam loss monitors (BLMs), collimators and BTV screens. In this project, you will ensure the integration of already existing Python and Java user code that was developed in an ad hoc manner by system experts via the use of MolR; define the test plans, tracking and reporting strategies with the system experts; scale the AccTesting framework to support the commissioning of thousands more operation systems.

Accelerator and Technology Sector (ATS):
HL-LHC Project - Junior Project Control Analyst

The High Luminosity LHC (HL-LHC) is an upgrade of the LHC to achieve instantaneous luminosities a factor of five larger than the LHC nominal value, thereby enabling the experiments to enlarge their data sample by one order of magnitude compared with the LHC baseline programme. Following five years of design study and R&D, this challenging project requires now about ten years of developments, prototyping, testing and implementation.
The use of state-of-the-art project management principles is key to ensure the appropriate follow-up and reporting of large scale projects like HL-LHC. CERN is looking for an engineer taking in charge the definition, update of and reporting of activities of several HL-LHC work-packages, based on CERN’s Earned Value Management (EVM) system.
​In this project you will be in direct contact with several HL-LHC work package leaders for keeping EVM data updated, provide support in preparing cost estimates and proposing revision of data following work package change of scope, schedule and/or cost-to-completion; take responsibility for the uniform application of EVM standards to HL-LHC work-packages. This work will be done in collaboration with the corresponding work-package leaders and supported by other BO team members; review the current EVM status of the work-packages under his/her responsibility (reporting follow-up, indicators interpretation) and write progress reports in preparation of Project Steering Meetings; actively take part in the project life cycle process, especially in re-baselining efforts.In addition, in collaboration with a team of developers you will define new features to be developed in CERN's EVM module, as well as dedicated reports and dashboards.


Beams (BE) Department:
Quality assurance service for the CERN Industrial Controls Frameworks

The Industrial Controls Frameworks comprise a wide variety of components and technologies. Given the criticality of the control applications and the large users’ community, testing of new releases of the Frameworks is of prior importance to ensure production-grade quality. Currently, this testing requires a substantial amount of work since many steps are performed manually and its coverage is insufficient.
​In this project, you will play a major role in the development of an automatic quality assurance platform, which should cover from unit tests to system and integration tests, as well as the automatic production of documentation. The platform will be used to asset the quality of the frameworks but also of the underlying technologies. Tests shall be executed nightly and web reports for developers must be produced to report on the status of the tests.
The participation in these tasks will allow you to develop a good knowledge of the GitLab continuous integration tools, Jira, Docker and SonarQube. Moreover, the work will also require the development of Python and SCADA scripts.
