DESCRIPTION
Together with a detector, the Base527 Series are complete spectrometer with integrated bias supply and preamplifier for PMT based detectors. It may be used for gamma-ray spectroscopy applications with NaI, LBC, SrI2 or similar scintillation detectors. The Base527 modules are suitable for detectors with 14-pin (standard version) or 12-pin photomultiplier tubes like the Hamamatsu R6231, R1306 (Jedec B14) or R9420, 9102B, XP2060B (Jedec B12). Special socket options are available on request.
The Base527 series are categorized in their respective computer interfaces and comes either with USB- (Base527), Ethernet & USB- (Base527E) or with a RS485 (Base527R). The whole module is powered from the USB interface port, or by “Power over Ethernet”. Due to the integration of all hardware components for a gamma spectroscopy system in one package, there is only one cable necessary to connect the system to a computer or network switch. The Base527 can be operated with our free of charge software programs, available for the entire MCA527 product family, such as WinSpec or WinMCS.
