This system operates based on a trigger signal delivered from the event timing system. Upon the receiving specified event code, the PXI DAC board outputs a waveform to the pulse driver, which consequently determines the current of the pulsed magnet. The combination of Windows 8.1 and LabVIEW was utilized to implement the control system since 2017. Nonetheless, due to the cessation of support for Windows 8.1, a system upgrade has become imperative. To address this, Linux has been selected as a suitable replacement for Windows and the EPICS driver for PXIe devices is thus required. This manuscript introduces the development of the novel Linux-based pulsed magnet control system.
