The nature of radiotherapy accelerators is briefly explained. It is argued that these complex safety-critical systems need a systematic basis for testing their software. The paper describes a novel application of protocol specification and testing methods to radiotherapy accelerators. An outline specification is given in LOTOS (Language Of Temporal Ordering Specification) of the accelerator con...

A stable, closely-controlled, high-intensity, single-bunch beam will be required for the SLAC Linear Collider. The characteristics of shortpulse, low-intensity beams in the SLAC linac have been studied. A new, high-intensity thermionic gun, subharmonic buncher and S-band buncherl accelerator section were installed recently at SLAC. With these components, up to 1011 electrons in a single S-band ...

Warm Dense Matter (WDM) is a challenging science field, which is related to heavy ion inertial fusion and planetary science. It is difficult to expect the behavior because the state with high density and low temperature is completely different from ideal condition. The well-defined WDM generation is required to understand it. Moderate energy ion beams (∼ MeV/u) slightly above Bragg peak is an a...

A device is described which is designed to refuel tokamaks of major radius -1 m and magnetic field -1 T by the injection of a compact torus. The injector utilizes an acceleration stage which adds kinetic energy to the compact torus so that it can penetrate the tokamak magnetic field. The performance of the device was found to be optimized in an unexpected parameter regime. It is theorized that ...

Nowadays, the data flow architecture is considered as a general solution for acceleration of deep neural network (DNN) because its higher parallelism. However, conventional DNN accelerator offers only restricted flexibility diverse models. In order to overcome this, reconfigurable convolutional (RCNN) accelerator, i.e., one DNN, required be developed over field-programmable gate array (FPGA) pl...

Understanding dynamics on ultrafast timescales enables unique and new insights into important processes in the materials and life sciences. In this respect, the fundamental pump-probe approach based on ultra-short photon pulses aims at the creation of stroboscopic movies. Performing such experiments at one of the many recently established accelerator-based 4th-generation light sources such as f...

The supersymmetric extension to the Standard Model offers a promising cold dark matter candidate, the lightest neutralino. I will review the phenomenological and cosmological constraints on the supersymmetric parameter space and discuss the prospects for the detection of this candidate in both accelerator and direct detection searches.

Gould and Robinson [SIAM J. Optim., 20 (2010), pp. 2023–2048] proved global convergence of a second derivative SQP method for minimizing the exact 1-merit function for a fixed value of the penalty parameter. This result required the properties of a so-called Cauchy step, which was itself computed from a so-called predictor step. In addition, they allowed for the additional computation of a vari...
