Wall current monitor showing 3 or 4 turns. This wiring problem has now been fixed. Intensity profile with circulating beam. The fixed features are from the first turn, while the moving features are from the second turn, during tuning. Intensity profile during transmission tuning beyond IP2.
Some beam goes around more than one turn.
Intensity profile with beam l osses downstream of IP12. Working on beam losses between IP12 and IP2. Beam losses around the entire BLUE ring, still with a couple of hot spots. Beam trajectory in sextant 3, during tuning. Beam losses recede towards IP4, as sextant 3 is tuned.
