From this page you can watch or download images and/or animations of electron injection, storage and SR-light generation in the storage rings ASTRID2 and ASTRID.
The animations are available in several types (mov, mp4, wmv), all of which should be supported by media players
N.B.: If you want to download the animation(s) instead of watching them, right-click on the links below and choose 'Save target/link as' from the pop-up menu.
Remember the animation prepared by Coldvision Studio showing the injection and storage of electrons in ASTRID (below)? Well a brand new animation has been prepared by Coldvision Studio which now includes ASTRID2 and the top-up injection process. The animation shows the injection of 100 MeV electrons from the microtron, into the booster ring ASTRID. These electrons are then accelerated to have an energy of 580 MeV, to allow top-up injections into ASTRID2.
The animation can be viewed or downloaded using the links below.

When downloading or viewing files, you have three options:
- Full version (QuickTime MOV files, 640*480 pixels)
- compressed MOV version (400*300 pixels) or
- compressed WMV version (640*480 pixels).
These animations have been developed by Coldvision Studio, www.coldvision.se
- The full animation can be watched here: Full animation (QuickTime movie, 79MB) , compressed MOV (18.5MB), compressed WMV (7.07MB)
- The first part can be watched here: First
part (MOV, 34MB), compressed MOV
It shows injection of the electron beam from the 100-MeV racetrack microtron into the storage ring/synchrotron ASTRID. After injection, the coasting beam (actually bunched at 3 GHz) is bunched tightly into 14 bunches, corresponding to the radiofrequency of 105 MHz in the storage ring after which it is accelerated to the maximum energy of 580 MeV.
- The second part can be watched here: Second
part (MOV, 18MB), compressed MOV
It shows emission of synchrotron radiation from the 14 circulating bunches stored at 580 MeV. Observe that the synchrotron radiation is emitted in the undulator and in the bending magnets. The synchrotron radiation has the time structure of the electron beam, and whereas most of the synchrotron radiation is absorbed in the vacuum chambers, a small part travels down the beamlines as light flashes.
- The third part can be watched here: Third
part (MOV, 8.6MB), compressed MOV
It shows the light travelling down the beamline, being deflected by a mirror before being dispersed by a grating. The slit selects a specific wavelength (colour), and this radiation hits the surface of a material. Photoelectrons are emitted, and these are energyanalysed by a spectrometer.
