- Gun layout drawings comparing R28-2 with R30-4 guns show data with input from S&A. They also include now R28 (14") and R30 (18") gun chamber dimensions and show why the z coordinate for the top flange is the same for both.File:Haysg-JL0091130-0100-SECTION 01-PHOTO-GUN TO VBV2102 R30 -3 and R28-2 including chamber dimensions.pdf
- 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.
