Data acquisition Hard- and Software
RoentDek has developed data acquisition concepts for PCs, especially suited for correlated multi-parameter read-out. It
consists of the software package
with plug-ins for certain hardware applications. Currently Windows XP and
Windows Vista and Windows 7 operating systems are supported. x64 (64 bit) OS systems are not supported for all hardware.
Windows 8 is partially supported but not yet for hardware read-out.
For the data acquisition with RoentDek delay-line detectors we have developed three types of TDCs. The TDC8HP,
HM1(B), and the TDC8 (for ISA and PCI bus). The fADC units are not yet documented in this manual. If you have purchased
fADC units please contact RD. For all data acquisition hardware modules there are separate more detailed manuals available.

4.1 The Time-to-Digital-Converters (TDC) for PC
RoentDek currently delivers different TDC modules for PC, the TDC8HP, HM1 and the TDC8, all suitable as stand-alone
units controlled by PC (
software): The TDC8HP is available as a PCI board. The HM1 can be delivered with an
ISA or PCI I/O card that needs to be inserted into the PC. The TDC8 exists as an ISA-PC plug-in board and in a PCI version
(this product line discontinued).
The TDC8HP system is based on the CERN HPTDC chip. The TDC8HP system consist of the HPTDC8 board and the
software. This card is in function very similar to the older TDC8PCI2 board.

The TDC8HP continuously record the digital waveform (high/low) on its inputs similar to a logic analyzer.
TDC8HP features are:
• 8 NIM compatible inputs on LEMO connectors with 25ps LSB
• 1 NIM compatible input on LEMO connector with 12.8ns LSB
• typical deadtime between multiple hits on one channel <5ns
• unlimited number of hits per trigger
• no dead time due to readout, new data is acquired during readout
• 4M Hits/s maximum readout rate, with
the read out rate is about up to 1.3MEvents/s
• 419µs range w. trigger logic enabled
• 2h range without trigger logic, can be extended by software (with
)
• adjustable trigger window (size, position of trigger)
• easy to use driver for windows operating systems
• on board storage for calibration data
• support for up to three event-synchronized boards
• 5V, 32-bit, 33MHz PCI target device
Typical applications for a TDC8HP include atomic physics experiments (e.g. momentum imaging, time-of-flight spectroscopy),
mass spectroscopy.
A PCI2PCIe adapter is available which allows the read-out of TDC8HP modules via PCIe bus and via further adapters to
laptop computers.
