SideKick
Supplier :
- Ultra-High Vacuum.
- Low Vibrations.
- Huge sample space, low footprint
The SideKick offer huge sample space under UHV, with surfaces outgassed before cool-down. Avoiding sample and windows getting covered with ice and allow to stay cold longer.
The SideKick mounts the cryocooler directly to the floor, removing energy and freeing up table space
ABOUT
SYSTEM FEATURES
Low-Vibrations, Low-Accelerations
Utilizing many novel vibration isolation techniques from simple linear springs systems to eddy-current damping to LIGO inspired non-linear stiffness canceling systems. Such systems have been designed, built, and delivered to enable research in demanding applications such as Scanning Probe Microscopy (SPM), Atomic Force Microscopy (AFM), and time-sensitive micro cavity research
Versatile Access
System includes 24 DC connections standard, six industry standard ISO63 ports available for more RF, DC, or fiber optics, and nine optical access ports (8 horizontal, 1 on top)
UHV Performance
Low outgassing materials, vacuum chamber bake-outs, as well as novel UHV sealing techniques have all been employed to achieve <1×10^11 Torr vacuum levels. We strive to fundamentally simplify these historically difficult systems.
Large cold space
200mm diameter cold sample plate with four cold interface panels for RF, DC, or fiber optics. Optional 250mm cold plate with eight cold interface panels.
Maximum Configurability
3D magnet, Low vibration insert for SPM (0,1nm PTP<), applications with nanopositioners, diamond anvil cell, integrated baekout hardware.
Easily Customizable
Flexible chamber and workspace to fit any application. 100mm tall sample space shown; taller space is available for applications with nanopositioners or low vibe insert for Scanning Probe Microscope.

“Congrats Four Nine Design on building a stellar line of (truly) low vibration cryostats. We hard bolted this Renaissance Scientific STM to the 4K plate. Four Nine Design is one of the RARE companies that understands that 'low vibrations' doesn't just mean low displacements on their own cold finger. Accelerations are much more pertinent. Four Nine Design gets this and we love them for it.”
“We love Four Nine Design cryostats. Most cryostat vendors get their UHV for free from cryo pumping, so they take liberties with greases, and varnishes, and other swamp algae that should never be there. Not FND. They get to UHV by baking, so before any cryo pumping. The Ren-Sci UHV magnet has a natural home here. If you open your cryostat and it smells, that's a swamp vessel. Never happens with 49 cryostats. UHV clean! »

When we launched Qnity, Four9 was the first manufacturer that came to mind. We had spent months admiring their cryostats in our spare time, and now we are proud to represent their exceptional products.
The SideKick is the only table-top cryostat on the market that has really been designed for quantum applications. General-purpose table-top cryostats draw a vacuum at room temperature down to 1.10-3 Torr and then reach 1.10-6 Torr by cryo-pumping, i.e. solidification of residual gas in the sample chamber.
Interaction of the sample (e.g. a trapped ion or cold atom) with these solidified residual gases induces strong experimental perturbations such as qubit decoherence. The SideKick doesn’t cheat, it get to UHV (1.10-8 Torr) by backing and thanks to its patented differential pumping technology, before reaches 1.10-11 Torr by cryo-pumping.
The result is a clean vacuum for very long experiments with no residual solid matter.
All this with a very small footprint on the optical table, as the cryogenic infrastructure is out of the way.
With SideKick architecture, the cold head and side tower are placed on the floor. Unwanted vibratory energy from the closed-cycle cryocooler remains away from the table. The table is free to float on pneumatic feet as it normally would.
