Gun fixture with alignment version 2: Carlos met with Gary Hayes and Keith Harding on April 23, 2024. We have one full visfture version 2 assembly ready for the R30-4 gun. Two assemblies were made of this version 2. One is installed in UITF with the R28-1 gun. The other is in TL1137. Thee feet from the fixture version 1 for the R30 gun HVC need to be 'transferred' to fixture version 2. Carlos will coordinate this with Neil Wilson. Gary is checking drawings and models to ensure fixture version 2 will work with R30-4 gun.
