What did science do today

Welp, this is my plan, I'm going to tell you what I did each day.
What do you think?
I will try and keep it short and interesting but I also wont be putting up much detail on things as it isn't good to give up my results to the world quite that freely just yet.

One side note, I ran into two guys from Sixty Symbols/Periodic Videos walking through TCD just before lunch. I watch their videos all the time so I don't mind saying I was a little star struck. There is a talk on this evening in the Science Gallery by the producer of the videos but I can't go because I am going to see an exhibit of Andrew's art.

What I've done today is mostly wrapped up with the design of the Faraday Cup I plan to use in future laser triggered plasma discharges. It is used to detect ions by biasing the centre copper cup and counting the electrons that essentially go missing when they pair with the ions (in simple terms and skipping stuff).

A magnetic field can be used to stop any secondary electrons which are knocked off by the impinging ions from escaping and being counted as an ion pairing (which would lead to extra ions being recorded that didn't strike the cup) and by using the shielding and aperture any electrons which are excited off other metallic surfaces by the strong emission of light from the plasma are stopped from impacting the cup and causing a decrease in the number of ions recorded.

So that's that, other things were done but I think one thing a day.
Thoughts, comments and opinions are as always more than welcome.

I really like this idea (and the catchy name!!) Its cool to see what you do and to get layman explanations for it too, also it'll be cool for you to see how you progress also :)
