We are pleased to announce that Kimball Physics have finished the new electron gun which will be integrated into the HREELM prototype (https://anr.fr/Project-ANR-14-CE35-0019, we can also find details about the HREELM project in the Projects section). This tour de force of ultra-high vacuum, electron optics engineering should allow the production of highly monochromatic electrons for imaging surface vibrational states (collaboration with Daniel Comparat Laboratoire Aimé Cotton and Lionel Amiaud ISMO). The electron gun was realized thanks to a Labex NanoSaclay & PALM innovation project and internal funding from the CEA.
