A self-amplified spontaneous emission (SASE) free-electron laser (FEL) is under construction at the Advanced Photon Source (APS). Five FEL simulation codes were used in the design phase: GENESIS, GINGER, MEDUSA, RON, and TDA3D. Initial comparisons between each of these independent formulations show good agreement for the parameters of the APS SASE FEL.
This paper summarizes work conducted at Colorado State University on the development of a two-frequency electron gun for implementation in a thermionic cathode system. Initial simulations were done using PARMELA and show up to 80% beam power loss. The cause of these losses is expected to be a result of the simulation technique. Compared to previous work… (More)
A non-invasive, real time, method for measuring the longitudinal emittance of electron bunches can be realized by using electro-optic (EO) detection schemes. Implementation of an EO beam diagnostic within the Colorado State University and Jefferson Laboratory beamlines necessitates investigation into how high average power beams affect various EO crystals.… (More)
Particle accelerators at X-band frequencies have been shown to reach gradients of greater than 100 MV/m [1,2]. Such technology permits more compact accelerators. One of our aims at the Colorado State University (CSU) Accelerator Laboratory is to adapt this technology to our L-band (1.3 GHz) accelerator system to increase our overall beam energy; however, we… (More)
The PlaceIQ platform is a large-scale data analysis system created on the concept of location. This paper is a system overview where we provide an description of the nature of the data sources, frame of reference, abstractions, algorithmic approaches, as well as the main design tradeoffs of this system. We also provide a list of some of the lessons we… (More)
