Magnetized Beam Transport Design Optimization for High Bunch Charge Beams

Magnetized and nonmagnetized beams are critical to achieve the luminosity goals of the next generation of electron-ion colliders. Maintaining magnetization and emittance of these beams from injection and transport through a long cooling solenoid is essential for this to work. For this Phase I, we will explore multiple concepts for the critical sections of arc transport and injector merger for high bunch charge nC level) magnetized and nonmagnetized beams. We will optimize to suppress the primary detrimental effects of coherent synchrotron radiation CSR) and space charge SC). We will consider the use of RF structures for merging and demerging beams. This will be done in collaboration with a national laboratory team, so that a Phase II could be a down selection and complete design of one of these systems. The team at Xelera Research LLC is uniquely experienced in designing and building novel and record setting electron sources, injectors, and beam transport systems, and has worked with both the Brookhaven National Laboratory and the Thomas Jefferson National Accelerator Facility teams for electron cooling.
