FLASH2 mirror protection system
In order to make sure that the mirrors are not damaged by short wavelength radiation a protection system takes care. The system is realized in combination of a server and jddd warning panels.
There are 2 mirror protection servers ( one for the 2 mirrors in the tunnel and one for the experimental hall)
The server checks that for the set wavelength the coating of the mirrors is appropriate. IF NOT the tunnel protection server will close PS1 and the hall protection server will close PS2. The closing is combined with a warning indicating the problem.
If everything is set properly and the possible wavelength is < 5.5 nm (checked by electron energy) this will be indicated in the tunnel view
If the protection server is not active this will be indicated when PS1 is closed and even more if it is open
If the protection server, wavelength server or mirror moving server is unavailable or has some errors the message will be displayed.
