Beam emittance measurements in the SPC2 injection beamline at iThemba LABS
Beam emittance is a property of a charged particle beam in a particle accelerator that is used to estimate the beam quality. It is length-based measure of the average spread of particle coordinates in position and momentum phase space. This attribute makes emittance a crucial beam parameter that …

Investigations of the physical properties of photoemission polarized electron sources for accelerator applications
… of space charge growth of a 100 keV electron beam passing through the Illinois/CEBAF polarized electron injection system was studied by measuring the beam emittance as a function of current. Finally, the thermal properties of GaAs were investigated by measuring the beam emittance as functions …

Development of a 300 KV DC High Voltage Photogun and Beam Based Studies of Alkali Antimonide Photocathodes
… This photogun will provide a magnetized electron beam for the future Jefferson Lab Electron-Ion Collider (JLEIC) cooler. This research describes key electrostatic design features of the photogun and evaluates the performance of the in-house fabricated photocathodes and the quality of the electron …

Final Muon Cooling For A Muon Collider
… they have a short lifetime of 2.2 μs and the beam is more difficult to cool than an electron beam. The Muon Accelerator Program (MAP) was created to develop concepts and technologies required by a muon collider. An important effort has been made in the program to design and optimize a muon …

The mass of 22^Mg and a concept for a novel laser ion source trap
Clean and high-quality radioactive ion beams can be prepared by combining ion trap and resonance laser ionization techniques. A feasibility study for such a laser ion source trap has been carried out which shows enormous improvement in the beam emittance, purity, and in addition allows for a …

Thermal equilibrium theory of periodically focused charged-particle beams
… theory of periodically focused charged-particle beams is presented in the framework of both warm-fluid and kinetic descriptions. In particular, the thermal beam equilibria are discussed for paraxial beams in periodic solenoidal and quadrupole magnetic focusing fields, and the theory is compared …
