BTVI26706
This BTV screen is the last in the part of TI2 which could be explored with beam on 28 October. It is located some 70 m after the lowest point in TI2, and some 700 m away from the temporary dump, which in turn is placed at some 50 m from the end of the TI2 tunnel, to avoid irradiating the LHC area.
First shot straight down the line at 12:03:47 on 28 October
