In high energy physics, the luminosity is one useful value to characterize the performance of a particle collider. To gain more available data, we need to maximize the luminosity in most collider experiments. With the discussions of tune shift involved the beam dynamics and a recently proposed "crabbed waist" scheme of beam-beam collisions, I present some qualitative analysis to increase the...

Particle accelerators are host to myriad nonlinear and complex physical phenomena. They often involve a multitude of interacting systems, are subject to tight performance demands, and should be able to run for extended periods of time with minimal interruptions. Machine learning constitutes a versatile set of techniques that are particularly well-suited to modeling, control, and diagnostic...

Electron cloud is a low-energy electron plasma that appears in particle accelerators and presents a challenge at virtually every large-scale particle accelerator complex. I will give a brief explanation of electron cloud how is formed and how it is distributed. Then I will discuss the measurements we've been making of the electron cloud at Fermilab, how we diagnosed a recent electron cloud...

TeV+ accelerators will either require extremely large and costly infrasturcture, or some development beyond conventionally limited acceleration gradients of ~50 MV/m. We discuss a relatively simple new longitudinal shape to drive ideal- transformer ratios and accelerating fields.

Beam emittance is an important characteristic describing the quality of an electron beam. Transverse emittance
measurements based on the quadrupole scan technique (quad-scan) have been widely used to characterize the beam phase
space parameters in linear accelerators. This technique will be implemented at the Advanced Superconducting Test
Accelerator (ASTA) at Fermilab. We plan on deploying...
