"Superconducting single photon detectors operated in an Adiabatic Demagnetization Refrigerator (ADR)"


Internship for first degree courses or thesis for Master of Science degree (second academic degree) 

Tutor: Mauro Rajteri

Description of the activities:
Superconducting light detectors are able to detect a single photon providing information on its energy, i.e. having an energy resolution. This property means, in the presence of monochromatic light, the precious ability to discriminate the number of photons contained in a light pulse.

INRIM is involved in the production and application of superconductive transition-edge sensors (TES), fundamental in single photon metrology and in the development of quantum technologies. Over the years, energy resolutions among the best in the world have been obtained.

This proposal concerns research activities on some aspects related to the realization of a cryogenic experiment for TES characterization and operation.

Among the activities to be carried out there are:

  • the completion of the new measurement system based on an adiabatic demagnetization refrigerator (ADR) capable to reach 30 mK;
  • the assembly of a cryogenic piezo positioner system to allow the study of the spatial response of detectors;
  • the development of labview programs necessary for the management of measurements and the acquisition of experimental data;
  • measurements and analysis of the electro-thermal response of the detector;
  • the study of the possible extension of TES to the detection of the energy of electrons accelerated in vacuum.

Openings: 2

Proposal validity:  until 31/12/2018
