High-brightness Cs focused ion beam from a cold-atomic-beam ion source
We present measurements of focal spot size and brightness in a focused ion beam system utilizing a laser-cooled atomic beam source of Cs ions. Spot sizes as small as (2.1 ± 0.2) nm (one standard deviation) and reduced brightness values as high as (2.4 ± 0.1) × 107 A m-2 Sr-1 eV-1 are observed with a 10 keV beam. This measured brightness is over 24 times higher than the highest brightness observ...
متن کاملNiobium Quarter-wave Resonator Development for the Rare Isotope Accelerator
There is a growing interest in the production of intense beams of exotic isotopes for research in nuclear physics and laboratory astrophysics [1]. The Rare Isotope Accelerator (RIA) is one such project being pursued by the nuclear physics community in the USA [2]. RIA calls for a superconducting cavity linac to accelerate the CW beam of heavy ions to ≥ 400 MeV per nucleon, with a beam power of ...
متن کاملHigh-Brightness Unstable-Resonator Semiconductor Laser Diodes
High-power high-brightness unstable-resonator edge-emitting semiconductor laser diodes with dry-etched curved mirrors were fabricated and characterized. The epitaxial structure was optimized for high output power operation and consists of a GaAs/AlGaAs gradedindex separate-confinement heterostructure (GRINSCH) with a single 980-nm-emitting InGaAs quantum well. The curved mirrors of the unstable...
متن کاملHigh brightness inductively coupled plasma source for high current focused ion beam applications
A high brightness plasma ion source has been developed to address focused ion beam !FIB" applications not satisfied by the liquid metal ion source !LMIS" based FIB. The plasma FIB described here is capable of satisfying applications requiring high mill rates !!100 "m3/s" with non-gallium ions and has demonstrated imaging capabilities with sub100-nm resolution. The virtual source size, angular i...
متن کاملBeam Transport, Acceleration and Compression Studies in the Fermilab High-brightness Photoinjector
A photoinjector is being constructed in order to produce a pulse train of up to 800 electron bunches, each with 8 nC of charge and a 3.5 ps rms bunch length. The spacing between bunches within a train is 1 s and the train repetition rate is 1–10 Hz. The desired transverse emittance is <20 mm mrad. An rf photo-gun delivers a bunched 4–5 MeV beam which will be accelerated to 14–18 MeV by a 9cell ...
