Simultaneous Noise and Impedance Fitting to Transition-Edge Sensor Data using Differential Evolution
Ari Pekka Helenius, Tuomas Puurtinen, Kimmo Kinnunen +1
We discuss a robust method to simultaneously fit a complex model both to the complex impedance and the noise data for transition-edge sensors (TES). It is based on a differential e…
Effect of a thin AlO_x layer on transition-edge sensor properties
Kimmo M. Kinnunen, Mikko R. J. Palosaari, Ilari J. Maasilta
We have studied the physics of transition-edge sensor (TES) devices with an insulating AlOx layer on top of the device to allow implementation of more complex detector geometries.…
Normal metal - superconductor decoupling as a source of thermal fluctuation noise in transition-edge sensors
K. M. Kinnunen, M. R. J. Palosaari, I. J. Maasilta
We have studied the origin of excess noise in superconducting transition-edge sensors (TES) with several different detector designs. We show that most of the observed noise and com…
