1. Friday 25 bunch fill dumped just before 08.00 (BLM in 5)
Morning and early afternoon
Multibunch injection studies (Beam 1)
Multibunch scheme operational by 15.00
Late afternoon
Fill for physics with 25 on 25 from 15.00
Lost after squeeze around – procedural problem
Try again – settings management issues end of squeeze – fixed
Collisions ~ – some losses at start
Issues with lumi scans – fixed
Stable physics through the night
Weekend
Physics running with 25 on 25

2. Friday
Note that we now have 2 TCDIH in TI2 with +/-5 sigma gaps, instead of nominal +/-4.5 sig. ******************************************** *** OK for MAXIMUM 5e11 p+ per injection *** ******************************************** until full verification of protection settings is made.

3. Fill 1251
In the attached plots, the following color coding is used: - black for witness bunches (zero collisions); - red for bunches colliding in IP 1 5 and 2 (3 collisions); - blue for bunches colliding in IP 1 5 and 8 (3 collisions); - green for bunches colliding in IP 2 and 8 (2 collisions).

5. Interventions needed
Magnetic probes in the machine for the studies related to the hump - access would be required in point 5 (GA, LW)
