About Slits

Over the last 25 years, JJ X-Ray has designed a large portfolio of slit systems used at x-ray and neutron facilities all over the world. Our top priority is to give the customer the best solution whether they need the slit system to be standard, modified or customized.

General Features

• Blade motion: Individually moving blades (IB) or blades moved in pairs defining the aperture size and translation movement for each dimension (AT).
• Position of Aperture in slit body: Centered (C), Off-Center (F), Asymmetric (A).
• Position of blades: The blades can define any size aperture within the gap and are typically fully overlapping.
• Number of blades: Normally the slits hold four blades but two blades are possible on request (DEMI-version).
• Slit Operation: In air (AIR), high vacuum (HV) or ultra-high vacuum (UHV, < 10^-8 mbar).

Common options

• Custom sized slits
• Steel slits
• Slits inside vacuum vessels
• Non-magnetic slits
• Copper braided cooled slits
• Water cooled slits (<4000W)
