For a variety of applications involving the control of ion beam size and current, NEC manufactures three basic models of beam defining slit systems varying in beam power ratings and geometries. Contact us to start an order.
NEC slits are ideal for applications requiring accurate control of beam size, determination of beam divergence, or limiting beam current. Ours slits are designed for use on high energy electrostatic accelerators or injection and high energy beamlines of medium to high current.
There are two slit elements per axis in each slit system. The slit element assemblies utilize all metal seals to the slit housing, with motion transmitted to the elements through stainless steel welded bellows. This allows for ultra high vacuum use.
The beam aperture material and the slit elements are either molybdenum or tantalum, allowing for beam power of up to 1000 W (BDS6) without melting the elements.
Custom element materials are also available upon request.
NEC produces three standard models of slits, with various configurations and options for each model. Below is a brief description of each model.
|Model||Beam Power Rating||Maximum aperture||Features|
|BDS6||1000W per element||1.5″ (3.8cm)||
For High Power Ion Beams
|BDS8||50W per element
For Lower Power Ion Beams
|BDS18||50W per element
For Large Diameter & Lower Power Ion Beams

All three models are available in manual or motorized versions. They are also all available as either single axis (2-jaw) or double axis (4-jaw). Several slit element options for the BDS8 and BDS18 are available:
