1 SPACEKIDS Workshop Cardiff 22 January 2014 Introduction and SPACEKIDS Overview Matt Griffin Cardiff University SPACEKIDS Workshop Cardiff Jan

2 SPACEKIDS Summary EU FP-7 programme (FP-7 Contract No ) Theme SPA : Key technologies enabling observations in and from space Advanced imaging technologies Detectors for observation purposes in space, allowing for development of novel instrumentation in the longer term Technologies and measurement methods for future Earth observation missions Spectropolarimetry and hyperspectral imaging SPACEKIDS Workshop Cardiff Jan

3 SPACEKIDS Summary SPACEKIDS Objective: - Develop Kinetic Inductance Detector (KID) technology for space applications - Astronomy - Earth observing Three-year programme (now at end of year 1) Participants - Cardiff University, UK - SRON, Netherlands - TU Delft, Netherlands - CNRS-NÉEL, Grenoble, France - CSIC, Madrid, Sapin - AimValley, Hilversum, Netherlands - QMC Instruments Ltd., Cardiff, UK SPACEKIDS Workshop Cardiff Jan

4 Rationale KID becoming detector of choice for direct detection in the FIR/submm Simplicity Ease of manufacture (thin superconducting film) Ease of multiplexing (FDM with many channels per feed-line) Performance Sensitivity (close to photon noise limit) Speed of response But many challenges in implementation for space applications SPACEKIDS Workshop Cardiff Jan

5 KID Principles SPACEKIDS Workshop Cardiff Jan

6 KID Principles SPACEKIDS Workshop Cardiff Jan

7 SPACEKIDS Summary Develop and demonstrate key aspects of KID technology for space applications Development of KID sensors Optical coupling methods Readout electronics Two lab demonstration systems in representative regimes Low background - Astronomy applications High background - EO applications SPACEKIDS Workshop Cardiff Jan

8 SPACEKIDS Key Objectives 1. Photon noise limited sensitivity 2. High and broadband optical coupling efficiency 3. Low cosmic ray susceptibility (small loss of observing speed) 4. Low microwave crosstalk between readout channels allowing high pixel count SPACEKIDS Workshop Cardiff Jan

9 Workpackages 1. Management 2. Review and analysis of requirements 3. KID development 4. System definition and hardware selection 5. Large-format array fabrication and testing 6. Technical coordination 7. Dissemination SPACEKIDS Workshop Cardiff Jan

16 SPACEKIDS Workshops Two open workshops to consider - Potential of KIDs - Possible future missions/instruments in which KIDs could be used Objectives of this first workshop: 1. Disseminate current performance and future potential of KID arrays 2. Investigate feasibility and benefit of using KID arrays for future space science and EO missions 3. Identify new experiments and mission concepts enabled by the use of KIDs 4. Review requirements for future missions SPACEKIDS Workshop Cardiff Jan
