Laser-driven (LD) proton sources are of interest for various applications due to their ability to produce short proton bunches with high charge and low emittance. These sources can be used in biological studies investigating improvements to radiation cancer therapy. Recently, the differential sparing effect on normal tissues versus tumors using the delivery of high radiation doses >10 Gy at...
Normal-conducting accelerating structures capable of supporting GV/m-scale electric fields offer a promising pathway to compact accelerators. Similarly, achieving such high fields in photocathode guns is critical for the generation of bright electron bunches. Our group has demonstrated the generation of ~0.4 GV/m electric fields on a photocathode surface in an X-band (11.7 GHz) photoemission...
Photocathodes are the electron sources of choice for accelerator applications that rely on bright and ultrashort electron bunches, including next-generation light sources and electron microscopes. These applications benefit significantly from photocathodes with low mean transverse energy (MTE), which directly contributes to higher beam brightness and better transverse coherence. However, the...
