Upgrades to the photoinjector and ICS interaction point chamber of the CXLS

<ns3:p>Details and design challenges of the photoinjector and interaction point chamber for the Compact X-Ray Light Source (CXLS) at Arizona State University are described. The CXLS uses Inverse Compton Scattering (ICS) to produce X-ray photons with energies in the range of 6-20 keV. The electron beam energy required to produce hard X-rays is reduced since the wavelength of the laser is quite short compared to that of a magnetic undulator. This unique aspect allows the accelerator vault of the CXLS to be much smaller than those in traditional facilities. This extremely compact size leads to much smaller costs and shorter timelines compared to large facilities. We review CXLS design elements and then describe operations experience and equipment upgrades with a focus on the photoinjector laser and the ICS interaction point chamber and their associated controls and beam diagnostics.</ns3:p>
