Kimball Physics is a key supplier of electron guns designed for use in a wide variety of ultra high vacuum (UHV) surface physics, space physics, and processing applications. Guns can be focusable for small spot size, for use in applications such as x-ray production, welding and RHEED; or for flood beams, for use in charge neutralization, electron beam scrubbing, space simulation and radiation damage studies. Range of Operation Energy Ranges: 1 eV to 100 keV Beam Current Ranges: 1 nA to 20 mA Spot Size Ranges: 15 μm (focused column) to 500+ mm (flood beams) Performance Beam Current Stability: feedback-stabilized emission current control; better than ± 0.1% per hour Energy Stability:  ± 0.01% per hour, ± 0.02% per 8 hours at full output to minimize chromatic aberration Convenience Customer-replaceable firing units Mechanical alignment during full operation Storable control settings Computer remote control / metering Operational Capabilities Fast pulsing / Beam blanking Deflection / Rastering Gun-mounted Faraday cups  

Kimball Physics ion gun systems, or ion sources, are used for surface physics, space physics, vacuum physics, charge neutralization, detection calibration, secondary ion mass spectrometry and ion injection for MBE. Range of Operation Energy Ranges: 10eV to 20 keV Beam Current Ranges: 1 nA to 2 μA Spot Size Ranges: 500 μm to 25 mm Performance Beam Current Stability: ±1.0% per hour with Emission Current Control or ±10% per hour after warm up without ECC for alkali metal sources. Energy Stability: ± 0.01% per hour, ± 0.02% per 8 hours at full output. Versatility Flexible Controllers: Independent fiber optic control and metering of functions such as ion energy, source, electron energy, field control, extract, focus, X - Y deflection and electron current control. Choice of Alkali metal ion sources allow for different ion species Operational Capabilities Fast capacitive beam or dual grid pulsing Deflection / Rastering Gun-mounted Faraday cups

Kimball Physics Multi-CF™ vacuum chambers and mounting hardware are particularly advantageous in UHV applications where there are spatial constraints and where a high density of experimental apparatus is required. Multi-CF™ vacuum chambers improve UHV performance with highly polished surfaces, contoured interiors and minimal welds. Designs are optimized for maximum internal access and internal volume. Multi-CF™ mounting hardware is standardized and interchangeable to save time and to ensure experimental set-ups can be assembled easily and reproduced accurately. Kimball Physics Multi-CF™ products are compatible with industry standard Conflat vacuum flanges. Standard chambers and fittings are made from Stainless Steel 316L and can be customized in Titanium depending on application requirements. Applications include: Compact UHV chambers Cold Physics chambers where port alignment accuracy is critical Portable low-cost UHV systems Electron gun / ion source housings Detector housings and subsystems Feedthrough clusters
