Linac4 cesiated surface H− sources are routinely operated for the commissioning of the CERN’s Linac4 and on an ion source test stand. Stable current of 40-50 mA are achieved but the transmission through the LEBT of 80% was below expectations and triggered additional beam simulation and characterization. The H− beam profile is not Gaussian and emittance measurements are larger than simulation. The status of ongoing development work is described; 36 mA H− and 20 mA D− beams were produced with a 5.5 mm aperture cesiated surface ion source. The emittances measured at the test stand are presented. During a preliminary test, the Linac4 proton source delivered a total beam intensity of 70 mA (p, H2+, H3+).

Surface Coordination of Multiple Ligands Endows N‐Heterocyclic Carbene‐Stabilized Gold Nanoclusters with High Robustness and Surface Reactivity
Shen, Hui; Xu, Zhen; Hazer, Maryam Sabooni Asre; Wu, Qingyuan; Peng, Jiang; Qin, Ruixuan; Malola, Sami; Teo, Boon K.; Häkkinen, Hannu; Zheng, Nanfeng (Wiley-VCH Verlag, 2021)Deciphering the molecular pictures of the multi-component and non-periodic organic-inorganic interlayer is a grand technical challenge. Here we show that the atomic arrangement of hybrid surface ligands on metal nanoparticles ... -

Bulky Surface Ligands Promote Surface Reactivities of [Ag141X12(S-Adm)40]3+ (X=Cl, Br, I) Nanoclusters: Models for Multiple-Twinned Nanoparticles
Ren, Liting; Yuan, Peng; Su, Haifeng; Malola, Sami; Lin, Shuichao; Tang, Zichao; Teo, Boon K.; Häkkinen, Hannu; Zheng, Lansun; Zheng, Nanfeng (American Chemical Society, 2017)Surface ligands play important roles in controlling the size and shape of metal nanoparticles and their surface properties. In this work, we demonstrate that the use of bulky thiolate ligands, along with halides, as the ... -
