Ion Pumps 

PST-050CU/AU Acter Pumps

Sputter ion pumps are one type of pump used to create ultra-high vacuums, and are used in many analyzers and accelerators. ULVAC's acter pumps were developed to enable single sputter ion pumps to create ultra-high vacuums on the order of 10^-10 Pa. They are designed for developing new elements (acter elements) with improved evacuation characteristics at ultra-high and extremely high vacuums, and to optimize magnetic fields.

Features

• Ultimate pressure in the 10^-9 Pa region (achieved with test dome complying with ISO standards)
• Double the pumping performance achieved by the inert gas enhanced pumping model (type AU)
  (compared with the ULVAC's conventional pumps)
• High pumping speed attained in the ultra-high vacuum region
• Pumping down to ultra-high vacuum in a short period of time
• Top-notch pumping characteristics in ultra and extremely-high vacuum region
  (discharging maintained down to the ultra-high vacuum region)

Applications

• Accelerators
• Electron microscopes
• Analyzers
