Digital Detector Emulators
The Digital Detector Emulators are multichannel instruments for the emulation of radiation detection systems.These devices represent an hardware application of the well-known Monte Carlo simulation method, synthesizing a continuous stream of pulses according to an user programmable set of statistical distributions such as energy spectra, time distribution, noise, etc.In addition, energy spectra and template waveforms acquired by other instrumentation (MCAs, digital oscilloscopes, etc.) can be loaded as a source of the emulation. The detector emulator can reproduce signals from a real energy spectrum that can be uploaded in the form of CSV or ANSI N42.42 files.A database of nuclides is provided to generate specific emission lines and Gaussian noise can be added. An user friendly control software is provided with the unit.
Signal pile-up is another experimental condition that can be fully emulated and controlled by the user.When the emulation process is reset, the sequence can be either re-initialized with new random data or reproduced the same many times, in order to study, for example, the effect of acquisition changes on the same data set.Each channel can be independently programmed with its own statistics.The Digital Detector Emulators are controlled by a dedicated Control Software with advanced graphical user interface for a full control of all the emulation parameters.
These features, together with the possibility to work as waveform/function generators, make the Digital Detector Emulators the perfect tools for testing and developing DAQ solutions, bringing an experimental setup on your desktop.
The user can either run different channels by uncorrelating or correlating them in different ways:
- Channel 1 sequence can be a copy of Channel 0 one shifted in time.
- A sub set of events from Channel 1 can share the same Energy Spectrum of Channel 0.
- The two channel scan work in a Master/Slave configuration, in which Channel 0 works as a trigger for Channel 1 that conserves its own statistics.
Another interesting feature (DT4800 excluded) is the possibility to generate different pulse shapes on the same channel with a predefined “mixture” percentage of the two, in order to emulate for example neutron pulses in a gamma ray background.The capability to add different noise and interference figures improves the emulation process, giving the possibility to operate out of ideal but not realistic conditions.CAEN Digital Detector Emulators are available in 5 models:
