This slit features an 80 mm x 80 mm aperture and a slit housing compatible with vacuum (10-5 mbar) application of the slit.

As with our IB-C80-AIR slit, this slit features four individually movable blades providing a large 80 mm x 80 mm opening with fully overlapping blades.

Special measures have been taken to ensure that the forces generated by the vacuum do not adversely affect the operation and precision of the blade motion.

For standard synchrotron applications, we provide tungsten carbide blades. For neutron applications, we usually provide B4C blades. A maximum blade thickness of 20 mm is possible without altering the slit system.

An actively cooled cold finger version of  IB-C80-HV is also available as an option (up to 50W per blade).
