Status update of the Y arm green lock:

  + Recent goal : automation of the single arm green lock

(Things done)

• Implementation of some realtime LOCKIN modules to detect the sign of the error signals.
• Modification of the realtime control model to accommodate the I/Q MFD signals, which will be available in the near future. (Of course the model file in the svn has been also updated)
• Update of the medm screens.
• Scripting of the auto-lock has been 30 % done.
• Succeeded in automation of closing the ALS loop. (I have tried several times and no failure was observed so far)

(Things to be done)

• Scripting a routine to detect the sign of the fine sensor signals.
• Development of a clever length scan algorhythm.
• Scripting handing off routines.
• Implementation of some lock-success binary bits to define the ALS state.
• Implementation of fail-safes.
