The T-VAC Chamber is designed for specific space environment test activities following the applicable ECSS standards. The chamber is operated within the Space Research Laboratory of the Centre for Energy Research (MTA EK). The deep vacuum within the chamber (pressure below 10-3Pa) is reached using a dedicated vacuum system containing a rotary and a turbo vacuum pump.
The chamber has a cylindrical free volume (length 51cm and Ø49cm) with an adapter plate for fixing the tested item. The temperature of this adapter plate can be controlled in the operation temperature range (-65°C and +95°C). The temperature control is performed by a LAUDA heater/cooler equipment filled up with Kryo-60 liquid. The controlled temperature point can be selected by the user. The control of the T-VAC system is realized by a dedicated control software (using PLC control).
The whole T-VAC simulation system can be operated using dedicated PC program (called SpaceSim). The test sequence (temperature profile, switch on/off, data acquisition details, etc.) can be programmed via the PC program in all details. Every measurement data (pressure monitoring, temperature monitoring, warning and error logs, voltage and current measurements in specific cases) is saved and archived with the predefined logging rate (up to 1 Hz). The real-time data visualization is also possible.
The environmental parameters in the T-VAC facility are monitored and logged (temperature, humidity). Test equipment and instrumentation as well as test items are inspected for visible cleanliness, where "Visible clean" defined as per ECSS-Q-70-01.
