X-Ray And Gamma Detector Systems
-
The XR-100CR is a new high performance x-ray detector, preamplifier, and cooler system using a thermoelectrically cooled Si-PIN photodiode as an xray detector. Also mounted on the 2-stage cooler are the input FET and a novel feedback circuit. These components are kept at approximately -55 °C, and are monitored by an internal temperature sensor. The hermetic TO-8 package of the detector has a light tight, vacuum tight thin Beryllium window to enable soft xray detection. The XR-100T-CdTe represents a breakthrough in xray detector technology by providing “off-the-shelf” performance previously available only from expensive cryogenically cooled systems. The XR-100-CdTe is also suited for measuring gamma rays.

Probes For Non-Contact Ultrasonic Testing
SONOSCAN CFC / CF
-
Due to the strong damping properties of air, low frequencies in the kHz range are used in air-coupled ultrasonic testing. It is therefore all the more important that the ultrasonic transducers offer a particularly high sensitivity in order to ensure high penetration and improved resolution. We achieve this, among other things, by installing preamplifiers in the receiver probe as well as by using our own Piezocomposite Technology, which enables a flexible use of the matching materials in our CFC and CF probes.

The SG1000 Signal Generator and PR1000A Preamplifier have been designed to simplify the measurement of shielding integrity in a shielded enclosure. When coupled with a high stability spectrum analyzer and an appropriate selection of test antennas, the SG1000/PR1000A combination can measure shielding effectiveness at all of the NSA 94-106 (supersedes NSA 65-6) defined test frequencies from 1 kHz to 10 GHz.The PR1000A amplifies the received signal from the test antenna and overcomes the high noise figure of the companion test receiver or spectrum analyzer. The PR1000A will ensure that the system noise figure will be less than 4.5 dB at all test frequencies from 1 kHz to 10 GHz. When used with a spectrum analyzer measurement bandwidth of 100 Hz, the system exhibits a sensitivity of -150 dBm at the test antenna output.To overcome high cable loss between the test antenna and the PR1000A assembly at 10 GHz, a remote low noise pre-amplifier (Praxsym PN 310-010091-001) is mounted directly onto the 10 GHz antenna.
