Source clusters can add more sources to your MBE system, either as thin-film deposition source in nanosciences or as doping source. Because of the large variety of different UHV systems each cluster is individually designed. We offer a large variety of source clusters based on our standard evaporation cells with four different cells mounted on a single flange.
By default the "quad" cluster sources are designed as four-cell-clusters. However we are to supply customized solutions with two cells, e.g., Dual Cluster Sources DCS on one mounting flange tailored to the customers' need.
The picture above shows a 4-fold source cluster with 4 x 0.2 cm³ PBN crucibles mounted on a DN40 CF (O.D. 2.75") flange. It is equipped with a water cooling block and a special multi-position rotary motion shutter which allows to shut off 1, 2, 3 or all 4 cells. The shutter can be regulated either manually or remote by a Multi-position Shutter Control Unit MSCU.
For QCS 100 another shutter option is the use of four individual shutters mounted on the same flange. Each one of the four shutters can be opened/closed independently. Each one can be regulated manually or remote by a Rotary Pneumatic Shutter Module RPM.
Application
The use of Quad Cluster Source increases the capacity of your UHV System by using only a single port for up to four individual sources.
Possible applications are organic material deposition or other material evaporation up to about 1100°C.
