Detailed experimental results of staging two laser-driven, relativistic electron accelerators are presented. During the experiment called STELLA (staged electron laser acceleration), an inverse free-electron laser (IFEL) is used to modulate the elect

Retrieved from: http://www.escholarship.org/uc/item/7ct3h4b4
A novel periodic magnetic field PMF optic is shown to act as a prism, lens, and polarizer for neutrons and particles with a magnetic dipole moment. The PMF has a two-dimensional field in the axial direction of neutron propagation. The PMF alternating

Development of Compound Refractive Lenses for x-rays
Autor: R. Tatchyn, R. H. Pantell, M. A. Piestrup, C. K. Gary, Jay Theodore Cremer, H. R. Beguiristain
Publikováno v: AIP Conference Proceedings.
One-dimensional and rotationally axisymmetric two-dimensional focusing of x-rays by plastic Compound Refractive Lens (CRL) systems are demonstrated and theoretical aspects behind the design of x-ray CRLs are presented in this report. X-rays between 8

Reducing slip in a far‐infrared free‐electron laser using a parallel‐plane waveguide
Autor: S. K. Ride, R. H. Pantell, J. Feinstein
Publikováno v: Applied Physics Letters. 57:1283-1285
There are several interesting applications for a picosecond, far‐infrared (100–1000 μ) free‐electron laser. One obstacle to its development is the slip that occurs between the electron beam and the radiation. This can be reduced by operating t

Psychosocial problems during child health supervision visits: eliciting, then what?
Autor: L, Sharp, R H, Pantell, L O, Murphy, C C, Lewis
Publikováno v: Pediatrics. 89(4 Pt 1)
An explicit goal of child health supervision visits is to gather information and provide guidance about the psychosocial problems of children and families. The purpose of this study was to determine the extent to which parents had opportunities to ex

Increasing patient knowledge, satisfaction, and involvement: randomized trial of a communication intervention
Autor: C C, Lewis, R H, Pantell, L, Sharp
Publikováno v: Pediatrics. 88(2)
A brief educational intervention to promote effective communication between physicians, children, and parents during pediatric office visits was designed and tested. A randomized clinical trial involving 141 children (5- to 15-year-olds) tested the e
