Ion pumps create high vacuum and ultra-high vacuum (UHV) environments in a variety of applications, ranging from portable mass spectrometers to large scale particle accelerators. All Gamma Vacuum ion pumps are designed to operate for 45,000 – 50,000 hours at 1x10-6 mbar.
All Gamma Vacuum ion pumps are designed to operate for 45,000 – 50,000 hours at 1x10-6 mbar. Lifetime increases linearly with decreased pressure. At 1x10-9, for example, an ion pump can last for many years.
Ion pumps are capable of reaching pressures below 1x10-10 mbar. Ultimate pressure of an ion pump is dictated by overall system conditions and materials. Ion pumps are shipped under vacuum at pressures less than 1x10-10 mbar.
Titanium Sublimation Pumps (TSPs) are often used in combination with ion pumps or independently to remove reactive gases from the vacuum environment. Combined with an Ion pump, the TSP allows for low ultimate pressures in a shorter amount of time. All TSP components are bakeable to 400 ˚C. NEG’s are reactive metals that have been pressed onto solid substrates or sintered into discs.
The amount of material used controls the speed and capacity of the NEG pump, but typically ranges from 50 to 3,500 ls-1 of hydrogen. As NEG’s become saturated with gases, they can be reactivated without venting to atmosphere. Their prime advantage is their ability to pump for extender periods without the need for power.
The DIGITEL family of Ion Pump controllers offers the right balance of performance, power and protection.
Small Pump Controller
The SPCe is a versatile way to fully operate ion pumps 0,7 - 270 m3h-1. An LCD pressure/current/voltage display along with standard serial communications makes the SPCe able to accommodate the needs of basic and advanced users.
The new QPC controller offers adjustable output voltage, nano ampere resolution plus up to four independent power supplies, allowing for high current control of up to four ion pumps independently.
Ion Pump Control
Ion pumps 360 m3h-1 and larger require higher currents for starting and higher pressure operation. The MPCe allows for high current control of two ion pumps independently (or up to four ion pumps in parallel) and has an easy-to-read touchscreen LCD display that simultaneously displays pressure, current, and voltage.
A TSP or NEG can be fully operated from the LCD touchscreen of the MPCe. They can be fired manually Or automatically based on the pressure of either ion pump the MPCe is monitoring.
