HARP-B is the Heterodyne Array Receiver Programme, B-Band Instrument

for the

James Clerk Maxwell Telescope

HARP-B instrument:

• 16-element heterodyne focal plane array, using super-conducting (SIS) detectors
• This will provide 3-dimensional imaging (simultaneous mapping and high-resolution spectroscopy) with high sensitivity in the 325 to 375 GHz (850-micron) band.
• HARP-B will be able to map spectral lines at a rate at least as high as that at which SCUBA maps the dust continuum. The spectral dimension will provide far more information than the continuum images.
• The Original science case for HARP-B is available on line

HARP-B is a collaboration:

MRAO

• prime contractors reporting to JCMT management
• mixers, LO injection system, IF amplifier
• cold optics, control electronics
• testing and integration
• SIS sub-contract to: TU Delft Institute of Microelectronics and Silicon Technology

ATC work packages

• include the K-mirror (image rotator)
• the cryostat with associated cryogenics
• cryostat handling
• some consultancy in areas of expertise

HIA

• LO,
• computer h/w
• control and observing software
