Award List:

Pulse Pileup Recovery for Energy Dispersive Spectroscopy

Award Year / Program / Phase: 1993 / SBIR / Phase I
Agency: HHS
Principal Investigator: Scott D. Davilla
Award Amount: $50,000.00

Pulse Pileup Recovery for Energy Dispersive Spectroscopy

Award Year / Program / Phase: 1997 / SBIR / Phase II
Agency: HHS
Principal Investigator: Scott D. Davilla
Award Amount: $404,257.00
Abstract:
Quantitative energy dispersive spectroscopy (EDS) x-ray microanalysis provides important information regarding the distribution of elements within a biological sample. The low elemental concentrations in biological specimens require dwell times of several seconds livetime to obtain spectra with… More

FLEXIBLE POLYMER ULTRAVIOLENT RADIATION INDICATOR

Award Year / Program / Phase: 1997 / SBIR / Phase I
Agency: HHS
Principal Investigator: Jeglinski, stefan a
Award Amount: $84,367.00

Improved Silicon Drift Detector Coincidence Rejection for Digital Pulse Processors

Award Year / Program / Phase: 2008 / SBIR / Phase I
Agency / Branch: DOC / NIST
Principal Investigator: Stefan Jeglinski
Award Amount: $90,000.00
Abstract:
The recent emergence of the Silicon Drift detector (SDD), for use in Energy Dispersive x-ray Spectroscopy (EDS), has made possible x-ray event streams with input count rates in the range of 1-10 Mcps. Modern digital pulse processors are therefore required to run at fast time constants to achieve… More

Development and Prototyping of a Digital Pulse Processor for Improved Coincidence Detection, Rejection, and Pulse Recovery, for High Count-Rate Silicon Drift Detectors

Award Year / Program / Phase: 2009 / SBIR / Phase II
Agency / Branch: DOC / NIST
Principal Investigator:
Award Amount: $300,000.00
Abstract:
The recent emergence of the Silicon Drift detector (SDD), for use in energy dispersive x-ray spectrometry (EDS), has made possible x-ray event streams with count rates as high as 1-10 Mcps. A problem with existing digital signal processing, as applied to SDDs, is the significant presence of… More
