Yesterday we installed the 2a2 window, the drive screw was torqued until 70 ft-lbs and we stopped, the yoke is not fully closed to its hard stop with roughly 7/8" to 3/4" still to go. Similar to identical conditions to 2a3 beamline window install, see https://elog.triumf.ca/TIS/RH-ISAC/647 for that install. Otherwise clamp looks centered and installed correctly.

Concerns with the cooling lines for the window WRT to the base of the shielding plug: There is no jog bend indicated on drawings for the transition of the window cooling lines from beamline center to the corner of the shield plug penetration. See photo for cooling line position on initial removal of shielding plug. It was decided to not add a jog for the shield plug and to carefully reinsert it being mindful of the cooling lines.  The shielding plug has a chamfer on the corner to allow the cooling lines to be routed to the top.

A new beam tube cradle is being manufactured where the old one will removed and the new one swapped with the beam tube in situ. Both sides of the window still need to be leak checked.
