OVERVIEW

Tokamak Energy has designed, constructed and operated ST40, the world’s highest field spherical tokamak. The measurement of electron temperature and density profiles using the Thomson scattering system is fundamental to achieving the ambitious scientific mission of ST40.
The successful candidate will take a hands-on role with day-to-day responsibility for the running and maintenance of the Thomson scattering (TS) laser beamline hardware and software as well as participating in ST40 experimental campaigns in the role of Thomson scattering operator. They will have responsibility for beamline characterisation and monitoring and for developing and improving the beamline and existing monitoring tools. The successful candidate may also have the opportunity to contribute to other diagnostics projects to support current or future ST40 experimental campaigns.

RESPONSIBILITIES

• Day-to-day running and maintenance of the laser beamline hardware and software for the ST40 TS diagnostic system
• Lead the planning, procurement and implementation of upgrades to the beamline hardware
• Work closely with the LabVIEW team to maintain, test and upgrade beamline software
• Participate in ST40 experimental campaigns in the role of TS operator
• Support other aspects of TS work as required
• Perform routine maintenance of the Class 4 TS laser system, arrange and facilitate service visits by the laser supplier
• Undertake Laser Safety training in line with the company policy and contribute to keeping TS system Risk Assessments and Standard Operating Procedures up to date
• Coordinate with the Facilities team to support routine testing and maintenance of safety systems and services within the TS laser room
• Interface regularly with other ST40 groups and other members of the DDC team (e.g. Technical Engineering Group, Electrical Systems, Design Team)

HAZARD-SPECIFIC / SAFETY-CRITICAL DUTIES

• Regular manual handling
• Working with or in the vicinity of class 3B or 4 lasers
• Working with ionising radiation
• Working with or in the vicinity of equipment that produces high magnetic fields
• Working at height (ladders, scissor lifts, cherry pickers & scaffolding)
• Work in hot or cold environments
• Working with electricity (LV & HV, operators must prove competence prior to use)
• Work with or in the vicinity of cryogenic fluids including liquid nitrogen
• Working with materials that are managed under the control of substances hazardous to health regulations (COSHH)
