During the March Meeting of the American Physical Society, Montana Instruments presented their new High Inertia, Low Acceleration (HILA) Workstation.
It has been designed as ultra stable, mechanical environment for cryogenic measurements. The system uses advanced vibration isolation technology with very low natural frequency together with mass compensation technology. This provides full insulation of external vibrations and minimizes the energy inside the sample chamber, which makes the HILA Workstation the ideal tool for vibration-sensitive applications like scanning probe microscopy (SPM) or optical resonator applications (resonant cavities).
Advanced low resonance technology isolates the sample platform from the cold head to drastically reduce the impact of the cryocooler pulse on sample vibrations. Users can easily change to split table operation for even lower accelerations.
The figure below shows how well the sample area is shielded from its environment. The blue line represents the acceleration of the sample platform with HILA technology. The spikes in the grey line represent the acceleration of the cryocooler.
HILA uses the same integrated and modular cold circuit board as the Fusion F2. All feedthroughs are already routed to the sample chamber and thermally lagged. This simplifies wiring and makes the system easy to use. It also reduces the overall heat load to the sample. The modular design of the circuit board allows plug-and-play adaptation to a variety of options. The flexible circuitry helps to manage wiring harnesses and prevents damages or disruptions. This makes the entire system more robust.
The HILA Workstation has an inside radiation shield diameter of 170 mm. The breadboard platform is 133 mm in diameter and leaves enough space for flexible experimental configurations.
HILA allows easy access to the sample and wiring, just like the Cryostation: Simply lift off the housing and remove the radiation shield for unobstructed access to the insulated cold breadboard platform.
Eight optical windows allow flexible access to the experiment. There are 7 radial ports at 45° spacing plus one top overhead window. The overhead window can be configured for low working distance imaging.
