“…Results of simulations and preliminary experiments demonstrating proof-of-principle indicate that the SLIM concept is applicable to circular hadron machines: for example, induction synchrotrons [8] or/and fixed field alternating gradient (FFAG) machines [9]. Such machines require (1) an accelerating system capable of handling a long bunch and (2) means that ensures the long bunch will be stable in longitudinal direction during acceleration.…”

A novel short-pulse concept (SLIM) suited to a new generation of a high gradient induction particle accelerators is described herein. It applies advanced solid state semiconductor technology and modern microfabrication techniques to a coreless induction method of charged particle acceleration first proven on a macro scale in the 1960's. Because this approach avoids use of magnetic materials there is the prospect of such an accelerator working efficiently with accelerating pulses in the nanosecond range and, potentially, at megahertz pulse rates. The principal accelerator section is envisioned as a stack of coreless induction cells, the only active element within each being a single, extremely fast (subnanosecond) solid state opening switch: a Drift Step Recovery Diode (DSRD). Each coreless induction cell incorporates an electromagnetic pulse compressor in which inductive energy developed within a transmission-line feed structure over a period of tens of nanoseconds is diverted to the acceleration of the passing charge packet for a few nanoseconds by the abrupt opening of the DSRD switch. The duration of this accelerating output pulse -typically two-to-four nanoseconds -is precisely determined by a microfabricated pulse forming line connected to the cell.Because the accelerating pulse is only nanoseconds in duration, longitudinal accelerating gradients approaching 100 MeV per meter are believed to be achievable without inciting breakdown. Further benefits of this approach are that, (1) only a low voltage power supply is required to produce the high accelerating gradient, and, (2) since the DSRD switch is normally closed, voltage stress is limited to a few nanoseconds per period, hence the susceptibility to hostile environment conditions such as ionizing radiation, mismatch (e.g. in medical applications the peak beam current may be low), strong electromagnetic noise levels, etc is expected to be minimal. Finally, we observe the SLIM concept is not limited to linac applications; for instance, it could be employed to both accelerate the beam and to stabilize the superbunch mode of operation in circular track machines.

“…In many systems, the inductive devices generate several high voltage pulses with the toroid cores working in MHz repeating rates, such as the acceleration cells of an Induction Synchrotron [1], and a multi-pulse Linear Inductive Accelerator (LIA) [2] and the cells of an Inductive-add Kicker Modulator [3]. Therefore these toroid cores require a very fast reset before each pulse [4], otherwise they will saturate during a voltage pulse [5].…”

Theory analysis and experiments have been done to find out the factors which decide on the self-restoration speed of low remanence toroid cores. The results show that in the right working circuit, the core with appropriate pulse permeability can be restored to its remanence after excitation within 1 µs without reset current. Therefore, the toroid core restoration in a MHz repeat frequency, multi-pulse induction cavity is likely to be solved by choosing the right material of cores and use proper working circuit.

“…In the first stage a low field magnet ring made of 2 Tesla superferric magnets will be installed [1]. The beams will be accelerated to 7 TeV with accelerating induction cells and barrier bucket induction cells to produce Superbunch beams [5,6]. The maximum center of mass colliding energy will be 14 TeV with the expected luminosity of 1.5 x10 35 /cm 2 /sec.…”

“…It allows ultimate use of longitudinal phase-space and is quite effective to substantially increase the beam intensity in synchrotrons [5]. We need two types of induction cells for this system, one for the accelerating induction cells, called A-IC, and the other for the barrier bucket induction cells, called BB-IC.…”

“…Recently proposals of applying induction acceleration to synchrotrons and hadron colliders were made, with the increase of the luminosity about 15 times as their advantage over the RF cavity acceleration [5,6,7]. We apply this induction acceleration to the design of the 62 TeV center of mass hadron collider with Superbunch beams in both stages.…”

A two staged 62 TeV center of mass hadron collider is proposed. In the first stage the center of mass energy will be 14 TeV with 2 Tesla dipole magnets. With Superbunch beams, the luminosity is expected to be increased by a factor of 15, compared with conventional acceleration using RF cavities. To accelerate Superbunch beams, the barrier bucket induction cells and acceleration induction cells will be used, which are made of FINEMET material. The core loss of the FINEMET is estimated to be acceptable. The synchrotron radiation of the collider is also estimated. In the second stage, 10 Tesla high field dipole magnets will be installed, and the application of Superbunch is being studied.
