IKI PTR-II
Description
The IKI Pulse Train Reader is a list mode
acquisition system for neutron coincidence
counting. It consists of an external hardware unit
and a user-friendly windows software package.
Measured data are transferred to the PC and
written to hard disk. The recorded pulse train, can
be evaluated with different predelay and gate
length, what is not possible with conventional
multiplicity shift registers.
Pulse train recording
The external hardware is based on common
FPGA circuits and transfers time-intervals
between consecutive neutron pulses to the PC
via USB line. Follow-up data are written in
binary format to hard disk by a PC program.
During measurement the time interval
distribution is displayed, what is useful for
diagnostics and research.
Pulse train evaluation
Multiplicity distributions as well as total and
coincidence count rates are calculated. The
evaluation is possible with different predelay, gate
length and long delay. The evaluation software is
very fast. Rossi-alpha distribution and die away time
are also calculated.
