Abstract We present the initial results of a proof-of-concept ‘smart alarm’ for Continuous Electron Beam Accelerator Facility injector beamline at Jefferson Lab. To minimize machine downtime and improve operational efficiency, an autonomous alarm system able to identify diagnose unusual states is needed. Our approach leverages trained neural network capable alerting operators (a) when anomalous...

The introduction of charged particle therapy in the hospitals could provide substantial improvements to external radiation therapy for cancer treatment. Many different types of accelerators have been proposed for installation in the hospitals, all with their own merits and disadvantages. In this report we discuss the requirements posed by charged particle therapy on the quality of the beam deli...

A single-cell/single-particle microbeam has been designed in which the radiation source is a high specific-activity alpha-particle emitting radioisotope, rather than a particle accelerator. The source is imaged at the focal point of a compound magnetic lens array. A novel precision microscope stage with an extremely compact design is included with the endstation s locating, targeting and imagin...

The Particle Beam Fusion Accelerator II, PBFA II, is now the largest pulsed power device in operation. This paper will summarize its first year and a half of operation for the Department of Energy (DOE) Inertial Confinement Fusion (ICF) program. Thirty-six separate modules provide 72 output pulses that combine to form a 100 TY output pulse at the accelerator center. PBFA II was successfully tes...

One particular laser accelerator is discussed in detail: the Template Laser (LT) Accelerator. According to one design, it employs mirrors placed periodically along the particle trajectory. According to another design, the mirrors are omitted, and additional electromagnetic fields are employed instead. The former design is a near field accelerator, but the latter is not. It is shown that contrar...

The design and performance optimization of particle accelerators are essential for the success of the DOE scientific program in the next decade. Particle accelerators are very complex systems whose accurate description involves a large number of degrees of freedom and requires the inclusion of many physics processes. Building on the success of the SciDAC-1 Accelerator Science and Technology pro...

Using channeling in a 5-mm crystal with bending angle of 0.65 mrad, a record high efficiency, over 60%, of particle extraction from accelerator was achieved. The extracted beam intensity was up to 5.2×10 11 protons per spill of ∼0.5 s duration. Also, the first proof-of-principle experiment on 'crystal collimation' was performed where crystal-serving as a scraper-has reduced the radiation level ...
