High
energy accelerators, used for nuclear physics, high energy physics, and advanced
light sources, produce beams with both low emittance and small spatial size. The
high average power of these beams preclude the use of conventional interceptive
diagnostics and make it very difficult to monitor beam properties in real time.
This project will develop a novel non-interceptive diagnostic based upon
Fresnel diffraction radiation, which is produced when the beam passes through a
slit or circular aperture. The diagnostic will be designed to operate at
energies up to and beyond 1 billion electron volts.
Phase I will calculate the spectra angular distribution of the radiation
and experimentally observe it at the Thomas Jefferson National Laboratory’s
3-6 billion electron volt continuous electron beam accelerator.
In Phase II the diagnostic instrument will be designed and then tested
under normal accelerator operating conditions.
Commercial
Applications And Other Benefits as
described by awardee: A Fresnel
diffraction radiation device designed to monitor the beam size, energy, and
divergence of high energy relativistic lepton and hadron beams online should be
useful to a wide variety of accelerator operators and users for both research
and commercial applications. Commercial
customers would include government, academia, and medical and industrial
accelerator facilities.
