Phosphor screens and scintillators

for the two-dimensional, visual detection of electrons, protons, heavy ions, x-rays and UV-light. The setup of a phosphor screen (scintillator) is schematically represented in the figure below. Not all layers shown must be combined.

GIDS GmbH offers phosphor screens in P43, P22, P46, and P47 that allow the two-dimensional, visual detection of electrons, protons, heavy ions, x-rays, and UV-light. Our standard phosphor screens perfectly match with our MCPs with an active diameter of 18, 25, 40 and 75 mm see MCP-Types datasheet Download PDF and they also match with the MCPs from Hamamatsu, Photonis, Burle and other MCP suppliers. Custom specific types are developed and produced on request.

The phosphor coating is prepared by the brushing process. The phosphor grains are agitated through a sieve or muslin gauze upon the plate which has been coated with some kind of binder. The phosphor is then brushed into the binder layer. The result in the adhesive bonding of the phosphor grains with high compressed density. Our brushing process leads to a very homogeneous layer structure.

The screens are stable under ultrahigh vacuum (UHV) conditions and can resist temperatures up to +200°C without problems. This stability is needed for the outgassing of a vacuum system to reach ultra-high vacuum levels

For special requirements, we also offer customized solutions. Thus we can for instance coat the active area of a CCD or CMOS image sensor. Generally speaking we can deal with substrates that do not correspond to our standard (in terms of material/dimensions). We will be pleased to work out with you a bespoke solution matching your very specific requirements.
