Session 3 : Critical aspects of accelerators
- Dirk Vandeplassche (SCK GEN)
Description
critical aspects of the machine
I will recall some salient aspects of reactor physics to review pertinent requirements and main specifications for accelerators driving a hybrid nuclear system with significant thermal power.
I will try to put this into the perspective of the historical developments. Due to time constraints, the term “review” (assigned from the organizing committee), or “overview”, as I have chosen for the...
The state of the art of accelerator physics and technologies allows to cope with the challenge of a compact cyclotron driver for an ADS demonstrator aiming at providing a proton beam power in the 5 to 10 MWatt range. The Single Stage Cyclotron Driver (S2CDTM) design studies developped by the AIMA DEVELOPMENT (AD) company show that this concept could bring industrial attractive solutions in...
The presentation will focus on the potential and the main critical issues for high power proton linacs to drive a subcritical reactor. As an introduction the main beam requirements for an Accelerator Driven System (ADS) will be reminded: to safely guide and accelerate a continuous wave (CW) MW class beam with a high level of performance, and thus with an extreme level of reliability. Then, the...
The talk considers alternative possibilities for ADS drivers. The energy and current required for a typical design are somewhat beyond the reach of conventional cyclotrons and
synchrotrons; linear accelerators can supply the required power but they are expensive, and their price is a barrier to the wide adoption of the ADSR concept. The Fixed Field
Alternating Gradient (FFAG) combines the best...
