The NDT-4000 is a Device Testing System for testing devices or samples in extreme vacuum and controllable uniform heat and cold cycle conditions. It is equipped with computer control, safety interlocks, and mulitple levels of access with password restrictions. It can be used to test devices/samples with automated heat and cool cycles for extended periods of time exceeding 36 hours with varying temperature conditions defined by the recipe. One of the common applications of this system would be space simulation. The approximate chamber size is 43" in length and 24" in diameter. A 16"x32" sliding thermal platform can be controlled within ±1 °C across its surface area for temperatures ranging from -100 °C to 150 °C. This platform is mounted on rolls so that it can be pulled out to 75% of its length for loading devices/samples. The chamber has provision for 4x 8" CF flanges that can be configured with an assortment of customer-defined feedthroughs for digital and analog communication, temperature measurement, power, RF, and other instrumentation needs. The standard vacuum system consists of a 1250 l/sec turbomolecular pump and a 680 l/min dry scroll backing pump. The base pressure of the system can be as low as 7x10-8 Torr and could reach 10-6 Torr range in less than 20 minutes.
