\section{Facilities, Equipment and Other Resources}
\label{sec:facil}

\subsection{Oberlin College}

\paragraph{Laboratory}

The PI has a dedicated research laboratory of approximately 300 square
feet in Oberlin's Department of Physics and Astronomy, which was
renovated as part of the comprehensive science facilities expansion
and renovation Oberlin completed in 2002.  Equipment relevant to the
project housed in the PI's laboratory include: spectrum analyzers,
frequency generators (up to 20 GHz), GPS clock and frequency
reference, oscilloscopes, and other standard radio frequency
electronics equipment.  Due to the additional space requirements
necessary for constructing the telescope and associated support
infrastructure, the college has obtained quotes from local facilities
that would have suitable space for rent, and this is included in our
budget.

\paragraph{Computer}

Oberlin has a Beowulf cluster supercomputer – funded through an NSF
Major Research Instrumentation grant – running the Linux 2.6
kernel. It consists of 64 dual-processor Opteron nodes and supporting
infrastructure such as a RAID array and gigabit Ethernet connections
between the nodes. Each node has dual AMD Opteron 246 processors
running at 2.0GHz. The processors each have 1MB of on-die cache. Two
head nodes control the submission of jobs to the rest of the
cluster. These head nodes each have 8 GB of RAM.  In addition to the
comprehensive client support services provided to the College
community by Oberlin's Center for Information Technology, faculty
in the natural sciences have access to a computer/software technician
for the Division of Natural and Mathematical Sciences

The PI's lab also maintains workstations for use by students and
postdocs with commonly used packages like MATLAB and IDL installed and
licensed.

\paragraph{Office}
The PI has a dedicated office within the Department of Physics and Astronomy, and the College has sufficient office space to accommodate a postdoc on this project.

\paragraph{Other}

The Department of Physics and Astronomy has three support staff who facilitate administrative, supply, and facilities needs. The College supports a full-time electronics specialist for departments in the Division of Natural and Mathematical Sciences as well as a half-time machinist.

\subsection{University of Arizona, Steward Observatory}
 
In 1992 Co-PI Walker established a laboratory (the Steward Observatory
Radio Astronomy Laboratory, SORAL) for the development of
state-of-the-art, THz receiver systems. SORAL possess all the
equipment (spectrum analyzers, network analyzer's, vacuum pumps,
cryogenic support facilities, etc.) needed for the development of
receivers. We also have 4He, 3He, and closed-cycle cryostats, a full
receiver testbed, local oscillator sources (including a Coherent/DEOS
FIR laser), and an antenna test range which allow us to characterize a
wide range of receiver systems. SORAL has licenses for Hewlett
Packard's High Frequency Structure Simulator (HFSS) and Advanced
Design System (ADS) software packages, as well as Agilent HFSS and CST
Microwave Studio. These programs are used to accurately model and
optimize mixers and other crucial receiver components. In addition, we
have licenses for optical and mechanical design packages such as
Zemax, Code V, Solid Works, and Inventor.
 
Using these facilities, SORAL has designed and built a number of
receiver systems; including single pixel 230, 490, and 810 GHz
receivers and the world's first 345 and 810 GHz arrays. SORAL has been
the primary facility instrument builder for both the 10m Heinrich
Hertz Telescope on Mt. Graham, Arizona and the AST/RO telescope at the
South Pole. Based upon the success of these instruments, the PI was
awarded a NSF Major Research Instrumentation (MRI) grant to design and
construct the world's largest submillimeter wave heterodyne
instrument; a 64 pixel, 345 GHz array receiver. The instrument (known
as SuperCam-1, short for Superheterodyne Camera) is a
multi-institutional project, much like ASTRO, and utilizes a commercial
4K cryocooler.


\subsection{Arizona State University, School of Earth and Space Exploration}

In August 2009, Dr.~Groppi will begin work at the Arizona State
University School of Earth and Space Exploration as an Assistant
Professor. Using funding already secured from other sources, he will
build a state of the art terahertz instrumentation laboratory, focused
on the construction of terahertz remote sensing instrumentation for
astrophysics, earth science and planetary science. A full suite of
microwave test equipment, a terahertz power detector and data
acquisition tools will be purchased to support both the laboratory and
this project. Licenses for CST Studio Suite, including CST Microwave
Studio (Full wave EM), CST EM Studio (magnetostatic) and CST Design
Studio (microwave circuit) simulation software will be purchased.
Dr.~Groppi is already well versed in the use of all these tools.

A key component of the lab will be a Kern Micro milling machine. This
3-axis CNC milling system is designed to direct machine structures
using classical milling techniques but with micron accuracy. The 1
micron RMS positioning and repeatability this machine offers, with
tools as small as 25 microns in diameter, allow automated machining of
complicated waveguide circuits in metal with verified 2-3 micron
precision on the part. Dr.~Groppi has extensive experience programming and
operating an earlier model of Kern micromilling system at the
University of Arizona, and has successfully trained technicians to
operate the machine to produce active and passive waveguide components
from 100 GHz to 2.7 THz. The flexibility of this tool in house, along
with all the necessary tooling, metrology equipment and software, will
allow the waveguide components for this project to be produced quickly
and economically. This fast-turn capability will allow many
generations of focal plane development for this project in a short
period of time and with relatively low incremental cost.


\subsection{University of Virginia, UVML}
