Recently, it was demonstrated that significant reductions in field emission on Nb surfaces could be achieved by means of a new surface treatment technique called gas cluster ion beam (GCIB). Further study as shown in this paper revealed that GCIB tre

Absolute measurements are presented for electron-impact single ionization of ${\mathrm{U}}^{10+}$, ${\mathrm{U}}^{13+}$, and ${\mathrm{U}}^{16+}$, and for double ionization of ${\mathrm{U}}^{10+}$ and ${\mathrm{U}}^{13+}$ from below the thresholds to

Sub‐micron‐scale surface roughness and contamination cause field emission that can lead to high voltage breakdown of electrodes, and these are limiting factors in the development of high gradient RF technology. We are studying various Gas Cluster

Frostbite injury to the extremities has the potential for disastrous effects. This review provides information valuable to the orthopedic surgeon to aid in the evaluation and treatment of frostbite. The pathophysiology and predisposing factors that p

Asymmetries, Ay, for π+ elastic scattering from polarized 3He were measured in the P33 resonance region, where the π‐nucleon force is strongly energy and isospin dependent. Preliminary results at energies of 142 and 180 MeV show large positive Ay

We propose the use of photodetachment of H− by a focused, diffraction‐limited laser beam for measuring the profile and transverse emittance of an H− ion beam.

Non‐invasive laser diagnostics are capable of measuring p absolutely and δp/p of high‐energy H− ion beams. A Q‐switched Nd:YAG laser, operating at 0.266 μm, can excite narrow auto‐ionizing resonances in the H− ion. The measured width of
