Visible camera cryostat design and performance for the SuMIRe Prime Focus Spectrograph (PFS)
Stephen A. Smee, James E. Gunn, Mirek Golebiowski +13
We describe the design and performance of the SuMIRe Prime Focus Spectrograph (PFS) visible camera cryostats. SuMIRe PFS is a massively multi-plexed ground-based spectrograph consi…
A Novel Reflectometer for Relative Reflectance Measurements of CCDs
Murdock Hart, Robert H. Barkhouser, James E. Gunn +1
The high quantum efficiencies (QE) of backside illuminated charge coupled devices (CCD) has ushered in the age of the large scale astronomical survey. The QE of these devices can b…
Prime Focus Spectrograph (PFS) for the Subaru Telescope: Overview, recent progress, and future perspectives
Naoyuki Tamura, Naruhisa Takato, Atsushi Shimono +97
PFS (Prime Focus Spectrograph), a next generation facility instrument on the 8.2-meter Subaru Telescope, is a very wide-field, massively multiplexed, optical and near-infrared spec…
A Modified Geometry With Reduced Optical Aberrations For Improved Time Domain Terahertz Spectroscopy
N. J. Laurita, Bing Cheng, R. Barkhouser +2
We present a modified geometry for time domain terahertz (THz) spectroscopy (TDTS) experiments. We show, through simulations and data, that a simple rearranging of the off-axi…
