The Proposed Fermilab Role

Discussions with the QUIET Collaboration on the Fermilab roleevolved over 2 years.

Our Goals are:

- To have a healthy intellectual partnership between Fermilab and the QUIET collaboration.

- To have a proper role for a National Lab.

- To use lab resources carefully and efficiently, building upon and enhancing the existing facilities for future projects.

Discussions with the QUIET Collaboration

Built Modest Calibration Tools for QUIET Phase I

3 trips to CIT/JPL

1 trip to Chile to take Phase I shifts

Hosted a QUIET Collaboration Meeting at Fermilab in June 09

Access to Phase I Data

Our Goal:

to learn the science and the experimental techniques

and developrole for the lab

Our Proposed Involvement in QUIET Phase II

Assembly of ~1500 W-band Polarization Analyzer Modules

A 2-year production runA critical need for QUIET Phase II.

The collaboration invited us to take on this role.

Precision Placementof 106 components

Components as smallas 200 m x 200 m

Very delicate HEMT components

Precision control of silver epoxy die bonding

Over 200 wirebondsper module

Harsh Cryogenic and Vacuum Environment

Technical Challenges

6

Upgrade Machines with powerful Labview and Vision System Software

Meeting the Production Goals

Utilize Coordinate Measurement Machines to Perform Automated Assembly

Strong interests from ATLAS and CMS in using automated assembly tools at Fermilab for the LHC silicon detector upgrades

A natural synergy between QUIET and Fermilab/HEP

Work to be performed at the Fermilab Sidet Facility

Micro Assembly Tools

New Tools for Die Bonding

Automated Wirebonding Machines at Sidet Facility

Will perform R&D of bonding mechanical strength in vacuum and cryogenic environment:

R&D to Guarantee High Assembly Yield

Reduces Need for Extensive Cryogenic Production Testing.

Quality Assurance is Critical

InspectionThermal Cycling of ModulesWarm Module Operations TestingCold Module Operations Testing

Management and DocumentationEnvironment, Safety, and Health

These are included in our cost and labor estimates

VNA test stations at JPL used for production testing and debugging of modules

We will replicate these test stations at Fermilab.

Summary

We’d like to propose a Fermilab/DOE partnership with QUIET-II

Project Construction Tasks

Delivery of 1500 W-band modules in 2 year production runIntegration and commissioning of 1 Receiver at Fermilab Calibration tools and window engineering analysis

Request to Fermilab/DOE:

Project Cost = $ 1.4M (base) + $0.4M (contingency)Operations Cost = $ 200K

Technical and Engineering Labor IncludedScientific Labor not Included

Production tooling material costs(NSF would provide funds for detector material costs)

Contribution to Chile site operations cost (~50 K$/year/institution)

Funds for Travel to Chile for Shifts and Installation

History of Intellectual Leadership and Core for a Strong Scientific Team.

Dodelson and Stebbins were among the first to understand the importance of primordial CMB polarization.

Expertise in RF, detector fabrication, and cryogenics.

The QUIET Collaboration is inviting us to take on a very important role.

Enthusiastic technical and engineering staff

A great follow-up project to DECAM, and wouldfinish before starting the LHC silicon upgrades.

We believe this project is a GREAT fit for Fermilab.
