NSLS-II Seminar

"Ketek GMBH Silicon Drift Detectors"

Presented by Richard Varall, KETEK Creative Detector Solutions, Munich, Germany

Friday, February 5, 2010, 1:30 pm — NSLS-II Seminar Room, Bldg. 817

Ketek has been the leading manufacturer of SDD's since the early to mid 90's. As many are aware, much of the development of the silicon drift detector was done at BNL. However, the production rights and patents eventually came under the control of the Max Plank Institute who sold the rights to Ketek. Ketek is located in Munich, Germany.
The first devices were 5 mm sq. surface area devices. Improvements in crystal size, count rate capability, energy resolution and peak to background followed with the primary emphasis of development geared towards the microanalysis and XRF commercial markets.
Ketek and the few other manufacturers have over the years virtually eliminated the Si(Li) detector from the commercial markets and Ketek is now developing the product more for the synchrotron market. The enhanced capabilities of the SDD in the areas of energy resolution, high count rate and ease of use will be discussed. Ketek now has crystal sizes up to 100 mm sq.
It is Ketek's intention to deliver a 7 element array to the APS by September of 2010. I am hoping the discussion can include NSLS input on how the multi-element array product can be designed to fit the applications of the NSLS and NSLS II.
