1.1 | 1 | 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. |
| 2 | |||
| 3 | There are 2 mirror protection servers ( one for the 2 mirrors in the tunnel and one for the experimental hall) | ||

| 11 | 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. | ||

| 15 | 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 | ||

| 24 | |||
| 25 | If the protection server, wavelength server or mirror moving server is unavailable or has some errors the message[[image:attach:image2021-2-10_17-51-59.png||thumbnail="true" width="150"]] will be displayed. IN the right lower corner it also shows the reason. clicking on the warning one gets to the protection overview: | ||

5.1 | 33 | == Opening PS1: == |
| 34 | |||
| 35 | to prevent opening PS1 if the mirrors are not save there is also some logic behind the open button | ||
| 36 | |||
| 37 | The "open PS1" button opens a new window , which should look like this: [[image:attach:image2021-4-13_16-38-3.png||thumbnail="true" height="150"]] | ||

| 53 | 0 = ok | ||
| 54 | 1 = closing absorbler | ||
