Rama called me and emailed a number of us concerning NDX readings when 1L23 was turned on. 1L24 was interacting with it as seen in figure 1 but neutron dose on INX 1L24-1L27 are clearly dominated by 1L23. I suggest the individual gradients be scanned to determine the offending cavities and their gradients reduced.
