Department: Engineering Design Department

Division: Heating & Current Drive Division

Section: Ion Cyclotron Section

Job Family: Engineering

Job Role: Engineer – 3

Job Grade: P3

Language Requirements: Fluent in English (written & spoken)

Contract Duration: Up to 5 years

As an Electrical Engineer you will oversee the design, procurement, installation and commissioning of the High Voltage (HV) Power Supply for the Ion Cyclotron (IC) Heating & Current Drive (HCD) system. These power supplies are procured partly by INDA as in-kind contribution through a Procurement Arrangement (PA) and partly as a direct IO contract placed to the industry. You will coordinate the engineering activities related to the integration, commissioning and operation of the HV power supplies into the Radio Frequency building and to be responsible for the interface with both the Pulsed Power Electrical Network (PPEN, HV) and Steady State Electrical Network (SSEN, LV). You will lead the system analysis, engineering simulation, and integration with the interfacing systems PPEN, SSEN and Reactive Power Compensation and Harmonic Filtering (RPC&HF). Moreover, you will be the responsible engineer of HCD team in the joint study and treatment of excessive reactive power, injected harmonics, frequency variances and protection strategy &setting of ITER electrical distribution system (PPEN and SSEN).

Background

The IC system will be used at ITER for Heating and Current Drive (H&CD) in a number of plasma operating scenarios, providing upto 20MW of power to the plasma. That power aims to increase the energy content in the plasma to assist fusion operation and control internal plasma parameters. The IC H&CD system is a powerful radiofrequency (RF) system composed of high voltage power supplies, RF sources, transmission line system and a set of antennas facing the plasma. Each RF Source shall deliver up to 2.5 MW RF power on Voltage Standing Wave Ratio (VSWR) 2:1, CW, in a frequency range from 35 MHz to 60 MHz (or 3 MW CW on VSWR = 1.5:1, frequency range from 40 MHz to 55 MHz). Each RF source consists of two parallel 3-stages amplifier chains with a combiner at the output. The IC HV Power Supply shall supply the last two stages of the amplifier chains with electrical power and with stringent requirements in terms of accuracy, voltage ripple, response time, turn off time and fault energy. Each amplifier chain is fed by its dedicated HV Power Supply. Each RF sources therefore requires 2 HV Power Supply units.

The IC HV Power Supply is closely related to the RF source it supplies, in terms of control, regulation, interlock, safety etc. and overall performance.
