SPECTRA 5011/5031 :: Universal alpha/gamma spectrometer

The SPECTRA 5011/5031 spectrosmeters have been developed to support companies and laboratories where radiation analysis is only one part of the work and therefore, the cost/time factor is a major aspect. But also professional radiological services will find a good solution for many purposes such as alpha spectroscopy or gamma spectroscopy with NaI or HPGe detectors.

The set up and handling of the device is very easy. This reduces start up times and avoids mistakes at the one hand, and at the other hand, also workers without special experience are able to operate the system.

Variable detectors arrangements and a lot of accessories simplify the adaptation to a wide range of various applications. For example, only minimal adjustment is required to turn an in-situ screening system into a vacuum spectroscopy system for the lab.

The signal imput connector of the SPECTRA 50xx provides as well the power supply as the bias voltage for the connected preamplifiers and shaping amplifiers (such as SARAD AMP01-03, MOD01-03, MOD01-04 and THERMO FHZ type NaI probes).

The imput signal is routed to a variable gain amplifier to fit the input signal to the subsequent ADC. The acquired spectrum is saved in the internal memory and can be transferred to a PC via the serial bus system. Therefore it is not neccessary to keep the PC connected during the whole measurement. A maximum of 15 SPECTRA units can be simultaneously connected to this bus-system.

The SPECTRA 5011 is a portable unit and can be operated either by the internal rechargeable battery or by a mains power adapter while the 5031 comes as a 19″ plug-in enclosure fitting into 19″ racks.

All setup functions are accessible by the PC software using an USB adapter.
