September 7, 2021A unique vibration damping system
The Ultra-Quiet Technology™ mechanically decouples the pulse-tube from the dilution to offer the lowest level of vibration on the market in continuous operation.
This low-vibration technology proved to be critical for some ultra-sensitive measures by limiting phonons that can affect supraconductors (low temperature detectors and mesoscopic devices).
The fusion of 3 technologies
Pumping duct gas exchanger
The pumping duct allows the system to transfer efficiently the heat between the 50K, 4K PulseTube stages and the 50 K, 4 K cryostat cold plates via gas, without any mechanical contact and hence negligible vibration transmission.
Bellow
The pulse tube head is coupled onto the 300K HEXA-DRY top flange via a leak-tight, X-Y-Z supple bellow (and enters into the pumping duct). The bellow allows to dump the mechanical vibrations of the pulse tube cold head.
Double-frame
The dilution refrigerator and the pulse tube head are referenced to two different solid, bulky frames. The pulse tube cold head is then tightly anchored to a bulky reference system, separated from the cryostat main frame, and allows to further prevent the vibrations coming from the cold head to propagate down to the cryostat cold stages.
