8 channel acquisition system with 6 ns time tagging + 64 bit 5/(6) INPUTS 100ps MULTISTOP
The MPA4T is a combination of a high resolution Multistop TOF System (1 START, 5 STOPS, 54 bit dynamic range) with a Multiparameter Data Acquisition System (4 or 8 channels).
100 ps per time bin, multiple-event time digitizer (TDC)
It can be used in ultra-fast Multi-scaler and TOF systems, in Time-of-Flight mass-spectrometry and time-resolved single ion- or photon counting. NEW !! Pulse-width evaluation with 100 ps precision enables the user to calculate the area, the pulse height of the detector pulse but also if multiple events have occurred - multiple events have a broader pulse width than single pulses.
In operation the sweep is started by a user-supplied start (trigger) pulse. Then subsequent events detected at the stop inputs are recorded, each in a specific time bin corresponding to the time of arrival relative to the start pulse. Compared to non-multi-hit devices, the MPA4T can evaluate stop events at a rate of 10 GHz state changes/sec, in the pulse width mode at 5 GHz. The MPA4T is designed with fully digital circuitry capable of accepting at least 65.000 events at peak (burst) input rates of up-to 10 Gbit per second.
The MPA4T has been optimized for the best possible pulse pair resolving while providing state-of-the-art time resolution available in digital designs. Six built-in discriminators can be adjusted for a wide range of signal levels. The single sweep time range enables the user to take data of up to 20 days (54 bit setting) or 30 min (44 bit setting with 16 TAG bits enabled), with a time resolution of 100 ps. In endless and wrap-around mode sweep repetitions with zero end-of-sweep dead time can be accommodated.
The high-performance hardware is matched by a sophisticated WINDOWS-based software delivered with each MPA4T - providing a powerful graphical user interface for setup, data transfer and spectral data display. Drivers for LINUX are available.
Multiparameter System (4 or 8 channels)
The MPA4T Multiparameter System is designed as an ultra fast list mode system with input ports for 4 or 8 ADCs, multiscalers or time-of-flight devices. 16-bit Ports can be combined to 32- or even 64-bit ports. For dependent single- and multiparameter acquisitions coincidence resolving times from approx. 20 ns (in steps of 20ns) to more than 1.3 ms can be selected. Eight 100 MHz 32-bit scalers are optionally available.
In "single mode" a 64 bit event word is inserted for each ADC. It can contain in addition to the ADC data the time in units of 6.4 ns (32 bits) and the sweep number (9 bits) for correlation with the TOF part. This mode is very interesting also for multiparameter applications as the time for each individual ADC event is available separately.
In "coincident" mode the event word has a variable length of multiples of 64 bit. It contains the ADC data of valid conversions within the coincidence time window, and may contain in addition the time of the event with 6.4 ns resolution (up to 48 bit), the sweep counter (up to 48 bit) and counter data of up to three scalers. It is possible to select special event patterns to drop unwanted events and reduce the amount of list data.
A 1 kHz timer word is inserted every millisecond. It is used for counting the real- and live time for each ADC. A Realtime preset using this timer is implemented in the hardware. The timer word can contain in addition the sweep number (16 bits) and the scaler #1 data.
Three auxiliary inputs/outputs are available, either as inputs to start a coincidence time window or mark events, or as outputs to monitor selected signals. One of them can be used to reject events.
TDC inputs and ADC inputs can be used simultaneously. ADC data are then recorded only during a sweep is running. This enables new experiments that were not possible before.
The MPANT for MPA4T software is a 32-bit or native 64-bit operating program developed to run under Microsoft Windows-XP/Vista/7/8 (32 or 64 bit). It is possible to define several single- and dual parameter spectra which can be simultaneously acquired and displayed. Calculated parameters can be defined to do evaluation of position-dependent detectors or any other applications.
One can accumulate single and multiparameter spectra in the RAM of the PC. Multiple windows of single and dual parameter spectra can be simultaneously displayed. List data can be stored on the local hard disk device or any other directly addressable storage device. Replay software for evaluation of list files is already implemented in the software and for pure TDC data available without extra cost.
