【 摘 要 】

This paper will present the implementation of the Microwave Kinetic Inductance Detectors (MKID) for mm/submm astronomy purposes in our cryocooler at the Energetic Cosmos Laboratory (ECL). Authors have used the robust cryocooler 106 Shasta from HPD Company. The refrigerator can cool down the temperature to 30 millikelvin. In this report, authors describe our experiences about millikelvin refrigerator, implementation challenges of MKIDs in refrigerator and the evaluation results.Published under licence by IOP Publishing Ltd.
