“…Usually, the accelerator magnets are located in a dedicated tunnel and the associated power converters are not installed in their immediate vicinity because of radiations issues, converter maintenance aspects, etc... However, to optimise the magnet powering system, the distance between magnet and transformer should be minimised [5] and, ideally, the pulse transformer should be located as close as possible to the magnet. This requirement often leads to integration issues since the space inside the accelerator tunnel is usually optimised and limited.…”

High current pulse transformers are widely used in particle accelerators for feeding pulsed magnets. Usually they need to be installed in very confined spaces, thus requiring compact design solutions. Several magnetic bias solutions are explored with the objective of reducing the core volume and total cost of the converter-transformer system. A concrete example is illustrated via the optimal design of two variants of the same pulse transformer, one with an air-gap and the other without air-gap but with an active magnetic reset. Results show that several solutions exist in order to optimize the volume of pulse transformers; however, this is always done at the expense of a more complex power converter topology or increased magnet volume.

“…Its technical specifications include an operating voltage of 25kV, a pulse current of 12.5kA, a pulse repetition frequency of 1kHz and a life span of 10 9 times [3][4][5]. Such switches have been applied in electromagnetic pulse [6,7], high temperature plasma flame technology [8], and particle accelerators in the United States [9]. Researchers from the Twelfth Research Institute of China Electrotechnical Science and Technology (CETS), such as Zhang Ming and Zhou Liang, have carried out a great deal of research and development in electrically-triggered and optically-triggered pseudo-spark switches.…”

Pseudo-spark switches have been successfully used in a variety of pulsed-power applications, including the European Large Hadron Collider, the Z-hoop fusion device, and the Dense Plasma Focus device. For such applications, it is important to reduce the trigger energy of the switch to save cost and improve stability. In this paper, a laser-triggered pseudo-spark switch is designed, which is triggered by a laser with a wavelength of 532 nm. Increasing the laser energy reduces the delay and jitter of the switch, and the laser energy threshold of 1.5 mJ for achieving switch stability can make the jitter of the switch less than 1 ns; in addition, increasing the hydrogen pressure inside the tube reduces the delay and jitter of the switch; and when the triggering energy is sufficiently large, the switch delay and jitter do not change with the switch when the anode voltage is changed, and the switch delay and jitter do not change with the switch. When the trigger energy is large enough, changing the anode voltage, the delay and jitter of the switch do not change with the switching voltage.
