FLASH radiation therapy calls for the delivery of fast bursted spills particles with dose times order milliseconds. The requirements overlap fundamental physics experimental requests that are being studied at CERN, albeit very different energy scales. In this contribution, a scheme extracting millisecond bursts from synchrotrons is explored by controlling third-integer resonant and chromatic ex...

The passage describes the development of a numerical framework in Python to create and process large dataset for time-series prediction using Deep Learning algorithms. is generated by solving Cahn-Hilliard equation spinodal decomposition binary alloy labeled train Prior training, dimensionality reduction performed Auto-encoders Principal Component Analysis. identifies three distinct latent dime...

PURPOSE Most existing methods for accelerated parallel imaging in MRI require additional data, which are used to derive information about the sensitivity profile of each radiofrequency (RF) channel. In this work, a method is presented to avoid the acquisition of separate coil calibration data for accelerated Cartesian trajectories. METHODS Quadratic phase is imparted to the image to spread th...

Non-linearity is a common feature shared by mechanical systems, whereas their linear behaviour is an exception. The irregular, chaotic behaviour finds out in many processes which are appeared in different natural and technical objects. The author has suggested applying the phase trajectory mappings for estimation of parameters of dissipative characteristics in the planes «acceleration– displace...

The purpose of this study was to gain an insight into the kinematics and kinetics of the single-handed dynamic moves on campus board and investigate the effects of increased rung distance on biomechanical parameters. Eight climbers, six males and two females, performed various single-handed dynamic moves on an instrumented campus board. Kinematic and kinetic data were collected during each jump...

Experiments are reported on inverse free-electron-laser acceleration, including for the first time observations of the energy change as a function of relative injection phase of the electron bunches. The microwave accelerating structure consists of a uniform circular waveguide with a helical wiggler and an axial magnetic field. Acceleration of the entire beam by 6% is seen for 6 MeV electron bu...
