Anechoic Chamber:

Anechoic Chamber

The need for an RF quiet invironment prompted the purchase of a 4,700 cubic foot anechoic chamber. The chamber was purchased, constructed, and certified by ETS-Lindgren. The chamber is certified from 10kHz to 10GHz, and utilizes a modular panel system that allows for a cost effective way to both expand the chamber, as well as replace the pannels to allow for higher frequency testing. A custom, all composite turn table, controlled was constructed by the center in order for us to have the ability to fully characterize antenna patterns. Attached to the chamber are vents that allow for air to be cycled multiple times per minute from either the top or the bottom of the chamber and safely vented outdoors. The anechoic chamber is installed inside our temperature and humidity controlled remote laboratory. This helps to prolong the material properties and the life of of the absorbant material within the chamber.

Building

In 2008, a new 6,000 square foot building was erected in addition to the current facility in order to further support the needs of the expanding center. From 2008-2011, the 6,000 square foot facility quickly became full due to the fast growth of the center. This, in adition to a number of large grants prompted the need for another 6,500 square foot addition. Ground work for the latest addition began in March 2011, and is expected to be complete in August 2011.

When fully complete, our 15,000 suare foot off-site facility is conveniently located a few minutes form the College of Engineering and is in addition to our three laboratories, and four offices located within Engineering Building-West. It houses a great deal of high-tech equipment, including (but not limited to); Anechoic chambers, concrete shielding rooms, high voltage sources, fast oscilloscopes, signal generators, time domain reflectometers, high pressure-switches, Marx-bank capacitors, oil tanks, lasers, computer simulation equipment, fume hoods and a full machine shop.

Concrete Shielding Room:

Concrete Shielding Room

The concrete radiation shielding facility located at the University of Missouri-Columbia Center for Physical and Power Electronics has been designed with the capability to accommodate a variety of high power electromagnetic sources. The facility was constructed through the placement of 860, 6x2x2 ft. concrete blocks, totaling 3.2 million lbs. of concrete, as well as 58,000 lbs. of steel support structure. The finished structure is 48x44x23 ft., supplying ample space inside to contain multiple sources.

Machine Shop:

Machine Shop

Housed within our remote facility is a full machine shop. It consists of two mills, a lathe, a drill presses, electric sanders, bandsaws, as well as many other common (and not so common) tools. An automated CNC machine is also available on campus for our center to use. Having a full machine shop in our laboratory facility allows students and staff to quickly fabricate, test, and make changes to any devices on the fly. Every employee using the machine shop takes a machine safety class, and is properly trained how to use each piece of equipment.

Pulser:

Pulser

This particular pulser was designed and built in house to examine switch recovery characteristics. Based on the current desgn, the pulser generates 70 ns long, 250-300 kV pulses at 250 J per pulse and 100 pps continuous mode operation. The pulsers internal switch can be scaled to operate at 1MV, 1KJ per pulse levels as long as the insulaton on the internal PFL is also increased in order to prevent flashover.
