SDS has brought out specialised power-supply units fitted to dedicated applications such as microchannel plates, streak cameras, Pockels cells, APDs, CCD intensifiers and mass-spectrometry detectors.
In addition, two benchtops and/or portable instruments are now available.
The GIPO series is composed of an adjustable high-voltage DC-DC converter with a high speed, high-voltage switch.
It can be instrumented or not, on demand.
Stability of the high-voltage power-supply integrated in the module is high (10ppm/degrees centigrade).
This device can switch 5.5kV in less than 3ns.
Pulse width, voltage and repetition rates can be adjusted by the user.
SDS can also provide a high-voltage linear ramp generator typically 0 - 1500V in 1us to 1ms.
These two parameters can be fully adjusted by the user.
The main application is streak-camera power supply as new or retrofit electronics.
The MCP series consists in a minimum-sized high-voltage power-supply unit for low-impedance microchannel plates with resistive anode readout and exceptional stability better than 25ppm/degrees centigrade over a -55/95C range.
The switching of the cathode power supply is controlled by the anode current-adjustable discriminator.
Benchtop models: LBT series (more than 52 standard products) presents AC-DC benchtop power supplies, low power (0.1 to 6W) and high voltage (0-100V to 0-8000V).
Negative or positive polarity is achievable depending on the model, with a typical residual ripple of less than 0.05 per cent.
Local or remote control is available via RS232, USB or fieldbus.
GAM detector is a low-cost, transportable / portable gamma ray radiameter with a PC-USB connection, integrating a GM tube selected for its large energy range.
An alarm mode is provided for fast activity change in the detection of radioactive material in the appropriate energy range.
An original filtering algorithm allows a reliable detection even for low activities, such as in harsh statistical conditions.
SDS will exhibit at Pittcon 2010 from 1 to 4 March in Orlando, Florida.
