The baffle on the +Y, +X wall of HAM2 has to be moved in order to enter the MC tube from the +Y door of HAM2. I readjusted it after it was moved, but, in case I am not around, the important thing is that it stick out about 2 cm from the tube wall. This means that the upper and lower corners of the baffle stick out past the wall of the beam tube just a tiny bit. I attach the photo from the original log, 75688, to demonstrate this.
