CONCLUSION AND FUTURE WORK
5.1. Conclusion
The main objectives of the projects have been determined since the beginning, and
they are to obtain and design a Photon Height Analyzer displayed as a histogram (or
spectrum) of the radioactive source and also to obtain information about the dead
time of the detector considering that we were involved in a low cost project.
In Chapter 2 we were conscious that, although our set up using an external divisor
probe (instead of a coaxial cable) will improve the data acquired, the digital
oscilloscope analogue to digital converser will increase the time of data acquisition of
our Photon Height Analyzer.
There exists the inconvenient caused by this time increase of the data acquisition
(around fifteen minutes, plus 45 minutes that runs the code); but it is permitted
because, we have replaced a commercial software and acquisition system card that
cost around 4000 € around teen years ago by our system that has cost 200 €. In
addition the system will be only used twice or three times every year.
It was determined that the amplifier is also a differentiator thanks to the image
obtained of the Bode diagram.
5.2. Future work
There are some ideas that could improve this project and could be done as a future
work, but they are out of this project possibilities.
First of all, could be a good idea to build an adapter between the amplifier (and
energy window) and the external divisor probe in order to ensure that during the
twenty minutes that takes the oscilloscope to acquire data, the connexion will be the
best.
Secondly, and example of how to create a dynamic data exchange is shown in
Annex VI just in case the manufacturer decide to send us a software that can allow
us to work in streaming mode (as they promised us.
Third, the possibility to change the hardware of the digital oscilloscope in order to
permit to obtain data faster could also be studied. It would be necessary a faster
analogue to digital converter and also a bigger internal memory for the oscilloscope.
