from 10:30 to 11:30 the shell TS5 has been dismounted:

• NO detached magnets

shell re-installed without miniskirt. central membrane screws tightened

160000 fsm_set_flat(/ff) no gain because miniskirt is missing. central membrane screws losened.

test of shell rotation:

1. rotation by hand: 0.5mm (on the edge), but there is still clearance between the magnets and their cold plate holes
2. then shell ripped

161000 screws tightened, then fsm_set_flat(/ff), then standard procedure:

1. screws losened
2. screws tightened
