To-Do list
This section is aimed at helping the Device Physicist remember the list of things that need to be done prior to the S800 tuning.
In S3 vault
Ensure that the object scintillator is in good conditions and has enough shimming positions to withstand the expected rates during the course of the experiment. The guideline document describing the installation and shimming procedure can be accessed

In data U6
Verify that stagearea in u6pc5 is pointing to the right place. After typing ls -l ~/stagearea
in a u6pc5 terminal, you should see: /user/s800/stagearea → /mnt/daqtesting/s800/exxxxx, where xxxxx corresponds to the experiment number. If the experiment number is not right, follow the following steps:
Create a experiment directory in /mnt/daqtesting/s800 by typing mkdir exxxxx
Go to the newly created experiment directory, and create subdirectories s800built, rawccusb, and rawvmusb
Remove the old stagearea link rm ~/stagearea
Create a new stagearea link by typing ln -s /mnt/daqtesting/s800/exxxxx ~/stagearea
Move the hidden setting file .settings.tcl from the previous experiment directory where stagearea was pointing to (under directory /mnt/daqtesting/s800/ ) to the current one. If you cannot find that file, there is an old version that can be copied from the directory /user/s800/converged_daq
Run the S800 DAQ with multilogger enabled, and take some data on disk to ensure that the newly created stagearea is properly filled
