Retrieving fields from proton radiography without source profiles

Proton radiography.

Energetic protons from an accelerator may be used to produce radiographs showing unusually high contrast but relatively poor spatial resolution.

Title: Proton radiography and tomography with application to proton therapy Short title: Proton radiography and tomography

Proton radiography and tomography have long promised benefit for proton therapy. Their first suggestion was in the early 1960s and the first published proton radiographs and CT images appeared in the late 1960s and 1970s, respectively. More than just providing anatomical images, proton transmission imaging provides the potential for the more accurate estimation of stoppingpower ratio (SPR) insi...

Magnetic Optics for Proton Radiography

High energy protons of 10 to 50 GeV can be used to radiograph dense objects. Because the transmitted beam particles undergo multiple coulomb scattering (MCS) in the object, a magnetic lens system is used to focus the particles exiting each point of the object onto a distant image plane. Without the lens, the MCS would seriously blur the radiographic image. Correlations can be introduced in the ...

Observations of electromagnetic fields and plasma flow in hohlraums with proton radiography.

We report on the first proton radiography of laser-irradiated hohlraums. This experiment, with vacuum gold (Au) hohlraums, resulted in observations of self-generated magnetic fields with peak values approximately 10;{6} G. Time-gated radiographs of monoenergetic protons with discrete energies (15.0 and 3.3 MeV) reveal dynamic pictures of field structures and plasma flow. Near the end of the 1-n...
