“…This effect can be realized by introducing any negative-voltage pulse power supply with fast rise and fall characteristics. A solid-state Marx generator [9] was developed for this purpose, and we refer to this type of beam chopper as an Einzel lens chopper [10], or Einzel lens longitudinal chopper in the first demonstration [9]. It bears emphasis that the present beam chopper serves both functions of transverse focusing and longitudinal chopping.…”

“…To fully demonstrate the chopping performance of the Einzel lens chopper, the chopped beam was measured with the Faraday cup placed in the monitoring bench [9]. In the experiment, the extraction voltage of ECRIS and the static Einzel lens voltage ensuring complete blockage of beam propagation were fixed at 10 kV and 13 kV, respectively.…”

The KEK digital accelerator (KEK-DA), which is a small-scale rapid-cycle induction synchrotron (IS), has commenced operation. A permanent magnet x-band electron cyclotron resonance ion source serves as the KEK-DA ion source and delivers various ions. A new Einzel lens beam chopper has been developed to provide the necessary pulse width of a few microseconds. The chopper is implemented by applying a rectangular pulse voltage generated by a solid-state Marx generator to the middle electrode of the Einzel lens. Momentum modulation at the bunch head and tail resulting from chopping in longitudinal direction has been observed. This intrinsic property of the chopped pulse has been clearly observed in a long drift (a free run in the circular ring) in KEK-DA.

“…Such an ion source is embedded in the 200 kV high voltage platform. Ion beams will be chopped by any longitudinal chopper, such as the Einzel lens chopper [18,19], so as to meet the bunch length required for the RAFFIA. The ion bunch is guided to the RAFFIA through the low energy beam transport line (LEBT) by including an appropriate momentum analyzer and charge-state selector.…”

A novel scheme for a racetrack-shape fixed field induction accelerator (RAFFIA) capable of accelerating extremely heavy cluster ions (giant cluster ions) is described. The key feature of this scheme is rapid induction acceleration by localized induction cells. Triggering the induction voltages provided by the signals from the circulating bunch allows repeated acceleration of extremely heavy cluster ions. The given RAFFIA example is capable of realizing the integrated acceleration voltage of 50 MV per acceleration cycle. Using 90°bending magnets with a reversed field strip and field gradient is crucial for assuring orbit stability in the RAFFIA.

Enter voltage is the advanced with CDVM's modules besides rate out-put to the capacitors to an enormously high voltage [20]. Then, an out-put to the capacitors are been connected to in a collection to be discharged into a weight.…”

a main objective of to the project is the Modular fusion solid state pulsed power generator with ripple content. Recently, a pulsed power structures have determined substantial packages. On behalf of to the reason, using a pulsed strength turbines that similarly to responding to a dreams of to the individual. This assignment proposes the converter that's the aggregate of to the Marx topologies besides sturdy state voltage multipliers to in a conjunction with remarks loop controller. It is the capable of to the generating excessive voltage pulses with diverse amplitudes at distinctivefrequencies to in which is the modular besides flexible. A resonant circuit used to in a this shape can reduce a strain on switching element besides growth an out-put to the voltage even as presenting the 0 modern-day switching on the behalf the a whole bridge converter. A controller is the operated with voltage oriented feedback structure controlling a duty ratio of to the power electronic devices. A Proposed Voltage Oriented Control method on the behalf the pulsed generator to reduce a switching loss besides to improve a performance. A system simulation has been done using Matlab/Simulink software. PI controller has been designed along with Pulse Width Modulation scheme to control a system.
