The NICOLE hybrid cooling system combines liquid nitrogen and electro-mechanical cooling. The merge of this two cooling systems provide detection unit non-stop operation for months without having liquid nitrogen to refill.
The NICOLE hybrid cooling system comprises Stirling-cycle cryocooler, cryocooler controller, Dewar vessel, pressure sensor and indicator, liquid nitrogen sensor and level monitor.
