MPIfR Bonn is responsible for the design, construction and characterization of the total power assemblies of 108 W-band, 6 Q-band and 2 Ka-band receivers. The group will also help with the assembly and optimization of the polarimeter subarrays (68 W-band receivers) before their integration into the large cryostats. |

Caltech is responsible for the procurement of the InP MMIC wafers from Northrop Grumman, and the evaluation of the wafers and delivery of the resulting chips to the module integrators (FNAL, SLAC and Manchester). They will lead an effort on the redesign and test of 44 and 95 GHz modules for improved performance and ease of assembly. Caltech is also responsible for upgrade and operation of the Chajnantor Test Facility, logistics in Chile, assistance with equipment deployment, assistance with observations, and development of the telescope control and observing software in conjunction with other institutions. |

Columbia is responsible for leading the effort to adapt the existing cryostat design for Phase II, and will fabricate and test the first two cryostats. Columbia will be responsible for the integration and optimization of the Q/Ka-band receiver, and will lead the effort to integrate this receiver with the corresponding telescope.

Fermilab has modestly contributed to Phase I since June 2007: several calibration wiregrids were built and used in detector optimization, commissioning, and calibration; a 20K black body was fabricated; and FE analysis of vacuum windows was performed. Funding from within Fermilab/DOE is being sought to participate in Phase II. The primary item to be delivered is production tooling, labor, quality assurance, and supervision to assemble approximately 1500 W-band modules, adapting existing tools in the Sidet facility to perform automatic assembly operations. The group also seeks to host and participate in the assembly, integration, and commissioning of one W-band 500-element receiver, perform FE analysis of the larger windows, and fabricate calibration grids. |

JPL is responsible for the design of the MMIC amplifiers using 35 nm technology and detector circuits using HRL Tunnel Diode technology. JPL personnel will also monitor both the NGC and HRL contracts. In addition, JPL will be working closely with Caltech on module improvements, supporting design and assembly activities. JPL will provide a low level of support for the MMICs and modules after delivery and deployment. JPL will provide design support for the QUIET-II optics, verifying the optical performance of the mechanical designs and comparing with the measured optical performance. |

KEK is responsible for the integration, optimization/characterization and deployment of a W-band receiver system, for the production and testing of the ADCs for all receivers, and for global design and development of the data acquisition system including the monitoring system, the latter a responsibility shared with Chicago. KEK is responsible for setting up an analysis center and contributing to development of pipeline software for data processing and analyses. |

Chicago will be responsible for the integration and optimization/characterization of the first W-band receiver, a responsibility shared with Fermilab. They will support an Analysis Center and develop one of the two analysis pipelines. Chicago is also responsible for the production and testing of two electronics systems for all receivers: the Module Assembly Boards inside the cryostats and the Analog Electronics Boards which are mounted on the cryostats. Responsibility for the DAQ and monitoring systems is shared with KEK. |

KIPAC is responsible for the manufacture and testing of the Q-band modules, and will design the Ka-band modules, septum polarizers and OMTs, in collaboration with Manchester University. We intend for the Q-band fabrication work to be carried out at the SLAC National Accelerator Laboratory using separate funds and for the Ka design and prototyping work to be carried out by campus members of KIPAC. |
|
|
|
Manchester will lead the design, production, testing and integration of 18 Ka-band modules in collaboration with the other QUIET institutions producing modules. Manchester will also deliver 16 split-block septum polarizers based on their own design on a timescale compatible with the Ka-band module delivery schedule. |

Miami is responsible for the design, fabrication and testing of the W-band, Q-band and Ka-band platelet arrays. Miami will perform the beam pattern measurements and return loss measurements of the arrays at the University of Miami. Once the platelet arrays are delivered, Miami personnel will assist in the beam pattern measurements of the telescopes, the deployment of the receivers in Chile and the subsequent observations. |

Michigan will lead and oversee the development, manufacture and deployment of the three 2m telescopes for QUIET. This work includes finishing all simulations needed to finalize and characterize the optical design of the crossed-Dragonne system including the ground shield. Concurrently, they will design the mounts and coordinate with a vendor to have them manufactured. Once the first telescope is delivered the group will align and characterize the mirrors using photogrammetry or a laser tracker and then perform near field and far side lobe beam maps. They will also oversee the deployment and commissioning of these telescopes in Chile. |

Oslo will be responsible for setting up and maintaining a data processing center (both hardware and techical support) capable of handling the expected petabyte sized data set, and developing the necessary software for reducing the raw data into high-level data products (component maps, power spectra, cosmological parameters etc.). |

Oxford shares responsibility for the design and construction of the telescopes (optics and mounts) with Michigan, Manchester and Stanford. Oxford will seek UK funding for telescope components and can in any case provide design effort and at-cost manufacturing. With Manchester, Oxford will design and build the Ka-band polarimeter modules. Oxford will also contribute to the analysis effort, particularly with mapping software, and will seek funding for a student dedicated to QUIET operations and analysis. |
