A Vibration-Isolated Detector Mount for a Pulse-Tube Cryocooler: Transmissibility, Temperature Penalty and Support Design
Year: 2026
Type: article
Abstract: This paper presents a computed design for a vibration-isolated detector mount intended for cryocooler engineering, with its performance, resource budgets and margins derived from stated assumptions rather than asserted. The headline results are: designed isolation resonance of 5 Hz; transmissibility at the 30 Hz structural harmonic of 0.0333 dimensionless; transmissibility at 60 Hz of 0.0109 dimensionless; total flexure stiffness required of 1.78e+03 N per m; static sag under the platform weight of 9.94 mm. Each figure was produced by the deposited computation from the inputs listed in the Methods, and the sensitivity of the conclusions to those inputs is examined in the Discussion. The design is a paper study: it is labelled, on its face and in this abstract, SIMULATED, NOT MEASURED, and no quantity reported here is a measurement of built hardware.
