1. Thursday Physics fill 1250 (with 13b) dumped at 10.30
BLM crate exchange IR7 (10.30 to 17.00)
Exchange of crate, check of fibre connections, check of dump request lines, check connections to BIS, etc
CMS and ATLAS access in the shadow
Beam again from 17.00
Quick attempt to clean up multi-bunch injection
Beam 2 is OK
Beam 1 losses .. Need to sort this out tomorrow
Physics fill with 25b
Try hybrid filling scheme B
B *1
Beams dumped just before (single BLM in 5)

2. Giulia on shift We are filled !!! 25 on 25 !
We used the Multi_25b_16_16_16_hyb scheme.
The following buckets are filled:
B1:
B2:

3. Thursday Filling 25b Very good for TI8/B2 – in 4b groups.
Close to BLM limits for TI2/B1 – even with single bunches.
And it worked !!!
