- External Mode
The External Mode has been implemented to automate the operation of the MBS and of the Gap after injection of the electron beam. To take advantage of the External Mode, follow the points below.
- Close the hutch in a safe manner, and turn the key to the EXP position.
- Push the SHUTTER button to open the DSS (Down Stream Shutter).
- Push the [External Mode] button on the right side of the STATION CONTROLLER monitor for at least two seconds.
The background color will turn blue.
- When the External Mode is operating, the lights around the key will flash alternately clockwise.
Please be aware that the External Mode will be canceled when the experimental hutch is opened.
It is recommended to use the External Mode when you are going out of the beamline, notably during the beam injection.
Furthermore, even when using the External Mode, it is still necessary to wait approximately 5 minutes after the Gap is closed before restarting the experiments, as the beam intensity is not stable immediately after the beam injection.
- We started the operation of GPFS.
The default Working Directory is /gpfs/data/(UserID), as indicated in the UGUI.
- Do not close the BBS during your experiments.
Close the experimental hutch and keep the shutter open if you don't perform experiments for a long time or if you finish your experiments.
When experimenting at AR-NE3A, it is important to remember the injection time of the electron beam into the PF-AR.
During the injection, the MBS (Main Beam Shutter) is closed, and the gap of the undulator is opened.
As a consequence, you cannot experiment during the injection.
After the completion of the injection, you will need to open the MBS and close the gap.
An announcement in the experimental hall will confirm the injection.
The status displayed at the upper right of the Ring status monitor is going to change according to the following sequence: Acceleration => Injection => Storage => User Run.
It takes about 15 minutes for the status to come back to User Run.
- When the status comes back to User Run, close the hutch (in a safety way), and turn the key to the EXP position (1 in the Figure below).
- Push the MBS open req. button (2 in the Figure below) to open the MBS. This procedure will take approximately 10 seconds.
Following opening of the MBS, the Gap should now close automatically.
- Push the SHUTTER button (3 in the Figure below) to open the DSS (Down Stream Shutter).
When the beam appears to be too weak, even though all the above steps have been performed correctly, a problem might have occured when closing the Gap.
As a consequence, please try to close the Gap again manually, as described below.
- Click the [Gap] button in the Special menu of the beamline control software UGUI.
- After appearance of the confirmation widget on the UGUI screen, the gap will be closed to a value corresponding to the current wavelength (specified within the UGUI).
