CMT is manufacturing cryogenic component test dewers. These dewers are optimum for testing cryogenic components at either 4K or 12K, depending upon the model. The dewer design offers flexibility to configure the cold plate for testing of almost all types of cryogenic components. The dewer is configured with 12 removable side plates that can be quickly modified to add RF connections. The dewer comes with a 66-pin hermetic DC connector that can be used for temperature sensors and DC wiring to the internal components. Two KF25 vacuum ports allow separate ports for Vacuum pump and gauges to be connected to the dewer. The dewer comes mounted in a mobile cart. CMT can provide engineering assistance to customize the inside of the dewer for your applications.
