Single-shot ultrafast electron diffraction (UED) was introduced as a viable way to measure ultrafast processes, such as structural transitions in materials. For UED, the dynamics in a sample are induced by a femtosecond laser pulse and ultrashort electron bunches are used to probe the ultrafast processes in the sample. The ultracold charged particle cloud (UCPC) source researched in this work i...

We propose a technique for producing electron bunches that has the potential for advancing the state-of-the-art in brightness of pulsed electron sources by orders of magnitude. In addition, this method leads to femtosecond bunch lengths without the use of ultrafast lasers or magnetic compression. The electron source we propose is an ultracold plasma with electron temperatures down to 10 K, whic...

The virtual source method is a technique to image and monitor below a complex and time-varying overburden without the knowledge of overburden velocities and near-surface changes. It is based on extracting the response between a given pair of receivers by correlating the wavefields recorded by them and stacking over the physical sources. There are several challenges that arise while generating v...

A photocathode-based low-emittance femtosecondbunch electron source is developed in Osaka University to reveal the hidden dynamics of intricate molecular and atomic processes in materials through experimentation such as time-resolved pulse radiolysis or time-resolved electron diffraction. The transverse and longitudinal dynamics of femtosecond electron beam in the photocathode rf gun were studi...

Urban operations (MOUT) are a key component of U.S. Marine training, yet assessment of performance during the later and more integrative training exercises is difficult because events happen quickly and walls impede full view. We are building a performance assessment system called BASE-IT that will collect data on positions, orientations, postures, and activities of Marines during training usin...

We reviewed how measurements of weak boson production at high energy ep and eγ collisions can provide important information on anomalous WWγ couplings. We also considerd the sinlge muon production through the virtual W decay at the Pohang Light Source (PLS) facility, and found this process is not adequate to be detected at the PLS until a large luminosity (∼ 1033/sec/cm2) Free Electron Laser is...

—The inclusion of remote experiments on mobile devices is a reality. Combining mobility and remote experimentation, it is intended to minimize the space-time barrier, providing faster access to information and so seek to encourage these students to continue their studies in careers in technology and engineering. The technologies presented in this paper has implemented its architecture from the ...

Electron-tracking Compton camera, which is a complete camera with tracking scattering electron by gas micro time projection chamber, expected to open up MeV gamma-ray astronomy. The technical challenge for achieving several degrees of the point spread function precise determination electron-recoil direction and position from track images. We attempted reconstruct these parameters using convolut...

MENTOR is a multidisciplinary research training program for graduate students in research field of mobility and posture disorders. Its members are distributed in a number of institutions across Montreal, creating challenges for the processes of collaborative research, joint supervision and scientific immersion. The purpose of our research project is to propose new distributed research and super...
