The Linear Pulse-tube coolers use a flexure bearing linear dual opposed-piston compressor to drive a pulse-tube cold finger. The flexure bearing compressor design, used in the LSF series of coolers as well, reaches an extremely long proven life time.
By coupling this compressor to a pulse-tube cold finger which does not contain any moving parts, an extremely long life time and availability can be reached.
In addition, the intrinsically-balanced compressor design and lack of moving parts in the cold finger results in a low vibration signature.
The low vibrations and extremely high field-proven reliability make pulse tubes the technology of choice for sensitive applications, ranging from sensitive civil application such as gamma ray spectroscopy, to cost-effective space applications, to 24/7 infrared applications such as surveillance where life time and availability are more critical than cooldown time or power efficiency.
Linear Stirling coolers are used in a variety of applications, both civil and defence, including surveillance, fighter aircraft sensor pods, and vehicle-mounted applications.
