DAQ system description
The data acquisition system used for recording the data that collected from the detector trigger output consists of CAEN V792 anolog-digital converter, V760 scalar, ortec gate and delay, ortec timing filter amplifier 474,ortec counter 875, P.S. 710 octal discriminator, and P.S. eight channel variable gain amplifier 777, and a CPU supported by CODA and ROOT. The data were collected manually from ortec counter, and digitally using the CAEN modules that were connected together and to the CPU by a VME crate.

Electronic Setup for the Neutron detector at the IAC
- Summary
The detector is installed in the IAC after modifications took place in the detector design.
The modifications are:
1- The area of the detector kipton window increased to the same size of the GEM cards( 10X10 cm).
2- The distance of the cathode from the first GEM increased up to 10 mm. previously the distance was about 3-4 mm.
Increasing the drift distance demands an increase in cathode potential to maintain the same values of the electric field in the old setup.
3- The detector is installed in a wooden box, in addition to a plastic scintillator which was placed to cover part of the detector window.
