Next Generation X-Ray Detector, Sahara III, Offers Order of Magnitude Improvement in Cooldown Times


Princeton Gamma Tech Instruments (PGT) has introduced the Sahara III, a new Silicon Drift Detector (SDD) which delivers exceptionally fast cooldown periods. The reduction in cooldown times allows an improvement in throughput and data collection. The Sahara III, now offers a cooldown period of less than 5 minutes (10mm2 detector module).

Princeton, NJ June 1, 2009 -- Princeton Gamma Tech Instruments (PGT) has introduced the Sahara III, a new Silicon Drift Detector (SDD) which delivers exceptionally fast cooldown periods. The reduction in cooldown times allows an improvement in throughput and data collection. The Sahara III, now offers a cooldown period of less than 5 minutes (10mm2 detector module).

Typical SDD detectors available today require a cooldown period up to 1 hour, limiting the data collection phase. For end users who are changing samples frequently, or in a shared vacuum requiring thermal cycling, cooldown times are critical to efficient system operations.

"The advancements in technology are possible because of PGTs compact SDD module size, the coldfinger mass is very low, and an optimized Peltier thermoelectric cooler," comments Company President Juhani Taskinen. "Our performance, our price, and the personal services we provide all contribute to the satisfaction our customers enjoy."

The Sahara III outperforms competition even without the significant cooling requirements typical today. For example, our recent in-house evaluation at an operating temperature of -15°C yielded comparable results to other commercial units operating at -60°C. This further differentiates the new technology from previous SDD options.

About the Company

Princeton Gamma-Tech Instruments (PGT) is a leading supplier of X-ray and Gamma-ray Detectors and Spectroscopy systems. We serve a broad customer base in scientific research, industrial materials analysis, and homeland security. PGT operates a full customer service and reachback program, backed by a modern manufacturing and service facility.

PGT has been a leader in the field of semiconductor gamma and x-ray detectors for over 40 years. When General Electric first produced high-purity (intrinsic) germanium crystals in 1972, PGT manufactured the first commercial HPGe planar detectors, soon followed by the first HPGe coaxials. Since that time, PGT HPGe detectors have explored outer space, gone to the depths of mines in search of beta-beta decay in enriched germanium, and found uses throughout the world in nuclear power plants, environmental measurements, and aerospace studies.
