Topic : Development of ultra-high stability power supply
Scope
Operation of particle accelerators in synchrotron radiation machines needs extremely precise power supplies (PS). Stringent demands must be fulfilled for design consideration such as stability, efficiency, accuracy, and electromagnetic compatibility. Specifically, for the magnet power supplies controlling the electron beam to attain desired characteristics with high stability, electrical specifications, and functional modes necessary to set up the high-performance power supplies must be addressed. In addition, to achieve ultra-high stability of the modern power supplies, both analog and digital control design and algorithm implementation are extremely mandatory with highly flexible control structures and monitoring capability. The PhD candidates will be working alongside the SLRI experienced engineers and researchers for their projects by designing and developing such a power supply for accelerator applications. Necessary simulation and real-world implementation (both hardware and software designs) are performed for practical purposes during their study.
Tools to be used: High-performance computer, simulation software, embedded controller boards (FPGA/microcontrollers), data acquisition modules.
Skill required: Programming/coding skill. Knowledge of electronic and electrical engineering/power electronics/digital signal processing/control system engineering is preferable.
