The model P7888 is one of the fastest commercially available four-input multiple-event time digitizers. It can be used as an ultra fast Multiscaler/TOF system in Time-of-Flight mass-spectrometry and time-resolved single ion- or photon counting.
In operation the sweep is started by a user supplied start (trigger) pulse. Then 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-multihit devices the P7888 can accept a stop event as soon as 1000ps/2000ps after a prior event - limited by the max. count rate only. The P7888 is designed with fully digital circuitry capable of accepting peak (burst) count rates of up to 1 (0.5) GHz.
The P7888 has been optimized for the best possible pulse-pair resolving while providing state-of-the-art time resolution available in digital designs. Five built-in 900 MHz discriminators are a useful addition to this board. 30/31 bit dynamic range equates to a time range of 2s. Programmable time offsets allow to record data up to an incredible 68.7 seconds with a time resolution of 1000ps/2000ps. The FIFO memory buffers all stop events at full speed (4 x 500 MHz) for at least 4 microseconds while a second 16k FIFO buffers the PCI transfer. Thus, average sustained data transfer rates of approx. > 10.000.000 /s can be achieved. For experiments requiring repetitive sweeps the spectral data obtained from each sweep can be summed in the PC enabling very high sweep repetition rates up to wrap around speed.
The P7888 is designed with "state-of-the-art" components which offer excellent performance and reliability.
The high-performance hardware is matched by a sophisticated software delivered with each P7888. MCDWIN - the MS-WINDOWS-98/NT/2000 based operating software - provides a powerful graphical user interface for setup, data transfer and spectral data display.
A DLL (Dynamic Link Library) with example programs for "C", Visual Basic and LabVIEW is available for operation in a Laboratory Automation environment.

FAST ComTec: P7889

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 occured - multiple events have a broader pulse width than single pulses. 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.

Ultra Fast Multiscalers / TOF

In Mass Spectrometry stop event pulses generated by ions arriving at the detector need to be precisely counted in the exact relation to their arrival time. The models, Series, and are one of the fastest commercially available fully digital multistop time digitizers with up to four inputs. FAST ComTec has specialised in the design and manufacturing of instruments for ultra-fast pulse counting that meets this criterion.

FAST ComTec: MPA4T

Coincidence data may contain the time of the event with 6.4 ns resolution, the sweep counter and counter data of up to three scalers, and two signal bits from auxiliary inputs. 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.
