Back to linac's commissioning

After this month that doesn't exist from the working point of view (not purely my case) we are back to do the linac's commissioning. Some projects are working fine to be used in the real world: the 'Fluorescence Screen Gui' and the 'Energy & Emittance Measurement'. I like to show the last layer view of this work here.

First of all the fsotr:
This is an snapshot of a (non-electron) beam take during this August. This is a light reflection that seems like a beam and the ImgBeamAnalyzer doesn't know about differences.

The pneumatic valve position can be selected in the top right off the screen and the values of the camera exposition are next to this. And the image is show on the left with the profiles and, if its the case the fit of this profile. Then all the data from this picture processed.

An important change from the last version. This analyzer was working doing polling of the camera, and every fixed time it ask for a new one and process it. Now this device is subscribed to the camera, and is this camera (using Tango way) who advice the analyzer because a new image is able.

Next project is the E&E measurement:
With this what is want is to measure the beam energy and then the emittance of the beam. In fact this is an scan of a magnet. For example, to know the energy of a beam the bending magnet can be used to know how hard is the beam to be bended: more energetic means more current to the magnet to bend it.

This projects will be used tomorrow in the linac's commissioning restart. Almost all the requirement are done, only rest the last ones that was asked for. Final tuning.
