Description
The multipurpose synchrotron radiation accelerator (4GSR), supported by Pohang accelerator laboratory (PAL), aims to achieve an ultralow emittance of less than 100 pm·rad, which requires a significantly reduced dynamic aperture size. The existing local bump injection scheme, which uses four kicker magnets to inject the beam, is unsuitable for 4GSR because it demands a large dynamic aperture. To solve this problem, PAL is researching the implementation of an injection method utilizing a single nonlinear kicker (NLK), with a prototype NLK made of G10 material. The magnetic field measurement system integrates the voltage across a single long coil to measure the magnetic field. It has an accuracy of less than 10 μm on each axis and can measure a space of 470 mm x 50 mm x 750 mm. The pulsed power supply is constructed with solid-state switches, capable of supplying a maximum pulse current of 10 kA for 7 μs.
