The invention provides active agents, such as paclitaxel, rapamycin, or 17-AAG, encapsulated by safe poly(ethylene glycol)-block-poly(lactic acid) (“PEG-b-PLA”) micelles. The compositions provide effective solubilization of drug combinations, such as paclitaxel, rapamycin, and 17-AAG, as well as others described herein. A significant advantage of PEG-b-PLA as a carrier is that it is less toxic than Cremophor® EL or DMSO, which are used in currently known compositions. Additionally, PEG-b-PLA micelles are easier to handle than DMSO and they do not possess a foul odor, which is a problem with formulations currently in clinical trials. Accordingly, the invention provides stable and biocompatible drug formulations that improve bioavailabilty without causing toxicity. It was also found that larger doses of individual drugs in micelle formulations can be administered compared to non-micelle formulations.

A charged particle beam system for imaging and processing targets is disclosed, comprising a charged particle column, a secondary particle detector, and a secondary particle detection grid assembly between the target and detector. In one embodiment, the grid assembly comprises a multiplicity of grids, each with a separate bias voltage, wherein the electric field between the target and the grids may be adjusted using the grid voltages to optimize the spatial distribution of secondary particles reaching the detector. Since detector lifetime is determined by the total dose accumulated at the area on the detector receiving the largest dose, detector lifetime can be increased by making the dose into the detector more spatially uniform. A single resistive grid assembly with a radial voltage gradient may replace the separate grids. A multiplicity of deflector electrodes may be located between the target and grid to enhance shaping of the electric field.
