Using LabView to control and capture data from a 5 electrode boxer quadrupole levitation system

[jonathanchye]

I am a research student working on a 5 electrode quadrupole levation system. I am interested of fully incorparating LabView software and NI hardware to control and capture this experiment.

First of all, I would need to create a boxer system driver circuit that is able to produce a waveform consisting of a 2 -15kHz, 5kVpp spike superimposed on the peaks of a 200-400Hz 3kVpp modulating auxilary waveform. This would be the Excitation and also the Main voltages. This will be connected to high frequency transformers to produce the necessary voltages to drive the electrodes. I have found a classical approach of a spike waveform generation circuit to handle this task. However, my question is could I use the LabView software to  develope a virtual circuit thus diminishing the needs of this separate physical ciruit to drive the transformers? In summary, the current system used is a TV fly-back and also an auto transformer layout. Several important points to be considered in this case are that the outputs of the 2 transformers used will have to be coupled together so that their signals could be superimposed upon each other and also the signals must be frequency and be phase locked together. I could provide detailed circuits if needed if someone is kind enough to help me.

The second challenge is to grab digital video data to be analysed. I am currently using PULNIX TM-6CN CCD camera to capture the levitating particles. I would also like to know if I could use LabView to grab graphical data from this camera with a over time and size measurement function.

I would very much like to know if LabView in conjunction with NI DAQ cards could handle the functions meantioned above. And if it is possible, what software and harware to I specifically need for this? Thanks in advance for your help in advance.

Hi,


Your local NI contact will be glad to inform you about this all. It is real hard to tell if all this is possible with LabVIEW without knowing all the details.


You can use LabVIEW to grab data, do some calculations, and use it to set an output. But it will depend on the needed speed if it is possible, and how the system will look like in your case. E.g. you might need to use cRio if you want speed, or and old pc if you don't. Again, your local NI contact can tell you all about this.


If you're new to LabVIEW, I advice you to think about a structure to put your program in. Don't just start with an example and build around it. Things will get messy. Ask someone with LabVIEW experience if you can. If you have a budget, you can also ask a 3rd party to make a nice structure.


Hope it helps,


Wiebe.

Hello.

I am a French student, and I am carrying out research on a 5 electrode levitation too.

I would like if you can provide me with some information about your circuit for the alimentation of those electrode (especially for the "boxer electrode ")

I will be very helpful for ma research! 

Thanks in advance for your help.

I expect that the original poster (OP) is unlikely to look here to see your request, since the original posts were almost 5 years ago, and there have been no subsequent ones. You might start with a google search of the online literature (the OP may have published, it was a graduate student), or if you can formulate specific LabVIEW related questions, post them here.
