|Title:||First Steps Towards Small Arrays of Mo/Au Microcalorimeters|
|Published:||December 01, 2000|
|Abstract:||We are developing small arrays of microcalorimeters based on transition edge sensors made with Mo/Au bilayers deposited on silicon nitride membranes and Au absorbers. The superconducting transition of the bilayers is adjusted to be around 130 mK with a transition width better than a millikelvin by use of the proximity effect between the Au and Mo films. We built a dilution refrigerator and wired it for 2 channel operation in order to study thermal coupling issues between thermometers within the array. The device fabrication process as well as preliminary results are presented.|
