A modern NEG controller in a compact design, optimized in both performance and cost with increased functionality that helps to reach ultra-high vacuum more conveniently for your application.
DIGITEL SPC-NEG controllers operate NEG pumps with a high pumping speed for hydrogen, which is the most relevant gas type in ultra-high vacuum. Unlike standard power supplies, the SPC-NEG can not only push a current into the NEG’s heater, but uses pre-defined routines, with certain parameters, such as current values or heating duration. Those values are chosen by the SPC-NEG depending on the connected NEG pump. The routines are customizable to allow for experiments with different parameters. Reliable operation is accomplished by open-loop detection as well as overload protection.
capture pumps have no moving parts. Vibration from moving parts and electrical noise is eliminated
capture pumps are built with radiation tolerant materials in excess of 108 Gray. Connectors and cables are also built with radiation tolerant materials for years of continuous operation
without any special consideration, capture pumps can be baked to 250 °C. Removing the magnets allows for hotter bakes up to 450 °C. Long hot bakes are critical to every UHV system
capture pumps require virtually no maintenance and avoid costly vacuum events because they are sealed from atmosphere, saving time, money and resources
initial cost is typically less than comparable specifications of other types of vacuum pumps. They use minimal or no power for years of low cost operation
