“…9: the amplitude modulation of the load voltage is the result of 7 modules dedicated to modulation control. The timing pattern used to control each modulation module is generated by an arbitrary waveform generator [3]. Figure 10 is a photograph of a complete fast dipole kicker pulser system consisting of two pulsers (one each for positive and negative 18kV), control system, diagnostics, and safety interlock system.…”

The Beam Research Program at Lawrence Livermore National Laboratory (LLNL) has been developing solidstate modulators for accelerator applications for several years. These modulators are based on inductive adder circuit topology and have demonstrated great versatility with regard to pulse width and pulse repetition rate while maintaining fast pulse rise and fall times. These modulators are also capable of being scaled to higher output voltage and power levels. An explanation of the circuit operation will be presented along with test data of several different hardware systems.

“…It should be developed for higher repetition beam delivery. Semiconductor devices are undergoing rapid development at present, making a high-voltage and large-current switching easier to achieve; thus, higher repetition rate kicker systems can be expected now [61]. On the other hand, a high-repetition rate operation of charging devices is a serious problem.…”

A new high-energy particle accelerator with static combined type of magnetic field and high-gradient resonant cavities is introduced for muon acceleration up to 300 MeV and proton acceleration up to 400 MeV. The accelerator concept is expected to realize Mpps-class rapid cycling high-energy particle acceleration in circular particle accelerators. Conceptual designs of the circular accelerator are discussed with an emphasis on short lifetime particles. The fundamental concept of particle acceleration and the related practical issues, which should be discussed when designing the accelerators, are described as well.

“…Available switches for systems with capacitive energy storage, which are primarily used, include: semiconductor switches (MOSFET/IGBT), magnetic switches, spark-gap switches, etc. Semiconductor switches have a long lifetime and a high repetition rate (hundreds of kHz or even MHz) [9][10][11]; the main problems are their limited capacity and high cost for large-scale applications. Magnetic switches are robust and can be also used for high repetition rates (several kHz), however, their energy conversion efficiency for short pulse generation is relatively low (typically 60-80%) [12][13][14][15][16], and there is always a primary switch needed.…”
