Past Projects
Balloon-Borne Projects
EBEX
The E and B EXperiment was a long-duration balloon-borne instrument designed to measure the polarization of the CMB radiation.
MAXIPOL
Cosmic Microwave Background Polarimetry Using a Rotating Half-Wave Plate, a bolometric balloon-borne experiment to measure the E-mode polarization of the CMB radiation.
MAXIMA
The Millimeter wave Anisotropy eXperiment IMaging Array is a balloon-borne cosmic microwave background anisotropy experiment.
SKIP
The Stratospheric Kinetic Inductance Polarimeter is a balloon-borne experiment designed to study the CMB, the CIB and Galactic dust emission in the Northern Hemisphere.
PIPER
PIPER is a balloon-borne CMB polarimeter designed to search for evidence of inflation by measuring the large-angular scale CMB polarization signal.
Ground-Based Projects
APEX-SZ
APEX is an on-axis Cassegrain telescope with a primary mirror that has a diameter of 12 meters. The APEX-SZ receiver is one camera mounted at the focal plane.
CLOVER
A UK-led project to detect the imprint of inflationary gravity waves on the polarisation of the CMB.
GLP
A LEKID-based CMB instrument design for large-scale observations in Greenland.
Satellite Design Studies
CalSat
A CubeSat for Calibrating Ground-Based and Sub-Orbital Millimeter-Wave Polarimeters
PICO Optics
The Probe of Inflation and Cosmic Origins is a NASA-funded study of a concept for a space mission to probe inflation and cosmic origins.
EPIC-IM Optics
EPIC-IM employs a large focal plane with 11,000 detectors operating in 9 wavelength bands to provide 30 times higher sensitivity than the currently operating Planck satellite.
Technology Development
Cryogenic Motor
A large-diameter hollow-shaft cryogenic motor based on a superconducting magnetic bearing for millimeter-wave polarimetry
Achromatic HWP
Made from a stack of three sapphire a-cut birefringent plates with the optical axes of the middle plate rotated by 50.5 deg with respect to the aligned axes of the other plates.
