SUMMARY:Observational cosmology at mm wavelengths with KIDs: the NIKA/NIKA2
  example 
DESCRIPTION:Observational cosmology at mm wavelengths with KIDs: the NIKA/N
 IKA2 example \nDr. Juan F. Macias Perez\n\nNext generation of CMB experime
 nts will require a large number of  detectors (few tens of thousands) in o
 rder to tackle the challenging  detection of primordial polarization B mod
 es. Furthermore, high  resolution experiments are needed for a detailed st
 udy of high redshift objects including clusters of galaxies,  proto-cluste
 rs and dusty galaxies. Within this context Kinetic Inductance Detectors (K
 IDs) are a serious  alternative to bolometers at millimetre wavelengths. I
 ndeed, KIDs are  naturally multiplexed and compact allowing us to construc
 t arrays of  thousands of detectors. Furthermore, KIDs present short time 
 constants  (below 1 ms) and have been demonstrated to be background limite
 d on  ground based observations. The NIKA camera, made of two matrices (20
 0 KIDs  each) operated at 140 and 240 GHz, has been installed successfully
  at the IRAM 30 m telescope in Pico Veleta,  Granada. NIKA has provided th
 e first ever scientific quality astrophysical observations with KIDs. In p
 articular  RXJ1347.5-1145, a massive intermediate redshift galaxy cluster 
 at z = 0.4516 undergoing a merging event, has  been successfully mapped at
  12 arcsec resolution by NIKA. NIKA is a general purpose camera and it can
  be also used for  other astrophysical objectives including for example ob
 servations of high redshift galaxies and proto-clusters,  and detailed int
 ensity and polarisation mapping of star-forming regions in the Galaxy. NIK
 A is a prototype of the NIKA2  camera that should be installed in 2015 at 
 the IRAM 30 m telescope. NIKA2 should have 2 frequency bands at 150 and 25
 0  GHz with about 5000 detectors in total and polarisation capabilities.  
 NIKA2 will be well-suited for in-depth  studies of the Intra Cluster Mediu
 m in intermediate to high redshift clusters and the follow-up of clusters 
 and proto-clusters  newly discovered by the Planck satellite. Finally, we 
 discuss the possibility of including KIDs in the next generation of  CMB s
 atellites as for example PRISM.
