The bulk of the work today was concentrated at X End. After consultation with Michael, we altered our plans slightly and then proceeded. Jim Warner unlocked the ISI so that testing could continue uninterrupted.I moved all the items out of the staging space in the lower level cleanroom and then staged the welding cart and laser for removal from the VEA. Mark, Randy, Ed and Tyler started clearing the garbing area. When that work was complete, I checked dust monitors (one to the left of the chamber door, one on the floor to the right of the chamber and one handheld: dust levels were very good (highest reading was 1 count at 3 um). We opened the roll-up door, moved the ISCT from the middle bay to the VEA under the Test Stand cleanroom and checked particle counts again. Things still looked good, so we moved various items out of the VEA and closed the roll up door. Particle counts were still good. The next task was to replace the door on the east side of the chamber and that was quickly accomplished. A garbing/staging cleanroom was was flown over the beam tube along with the engine hoist in preparation for door removal early next week. The dismantling of the Test Stand cleanroom started after lunch. That gets us through #15 on a checklist of 30 items.
