This section is aimed at helping the Device Physicist remember the list of things that need to be done prior to the S800 tuning.

• Install the focal-plane scintillator with the right thickness (1mm or 5mm)

• 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 here

• Arm dump switches

• Make sure object ion gauge is off

• Ensure viewer is ready in S800 target station (pivot point)

• Make sure gas bottles for FP detectors are open

• Make sure Intermediate PPACs have gas

• Start Software applications (in computer u6pc5)

• 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
  • Create the stagearea link by typing ln -s /mnt/daqtesting/s800/exxxxx stagearea
  • Run the S800 DAQ with multilogger enabled, and take some data on disk to ensure that the newly created stagearea is properly filled

• Make sure that scaler directory has the right experiment number:
  • In a u6pc5 terminal, go to /user/s800/operations/daq/scalers/exxxxx, where xxxxx corresponds to the experiment number.
  • If there is no directory for the current experiment, create one
  • Run scalers in /user/s800/operations/daq/scalers/exxxxx by typing goscalers

• Put 10 Amps in Spectrograph dipoles

• Start gas in detectors

• Enable CRAD04 with a rate limit of 20 kHz (CRAD04 looks at E1 up FP scintillator) via PanelMate CRAD_RF_Intlks.ui (PAGE 01) located in directory \\exp\files\control\ncsdata\General\Qt\Templates

• Set spectrograph Brho (coordinate with experimenters)
