1. Injection Studies: 50 ns
ABT/BTP

2. Friday
First try of injection with 50 ns bunch separation - Injected 12 bunches per shot for the two beams (96 bunches) - Tried to steer trajectory in TL to improve losses at the TCDI and reduce injection oscillations ==> losses stay high (20-30 mGy), injection oscillations ~ 0.5 mm High cross talks at MQ for Beam 1, de-bunched beam losses for Beam 2  beam dump

Check TCDI centering

4. Saturday New golden trajectory for TI2
108b scheme filled with 12b injections - interlock BPM tests OK
Capture losses and uncaptured beam from SPS improved with respect to day before (confirmed also by LHCb)
Centering scans of 3 TCDIs in TI2. Found new centre for 1 collimator TCDIH  centre moved by mm
TI8 TCDI Collimators to be scanned
Opening the collimators TCDIH and TCDIH from +/-4.5 to +/-5.0 sigma  improved the losses by a factor 4 (x2 per collimator).
Injected a few batches of 24bunches at 50ns for both beams.

5. Sunday
Injection of batches with 24 bunches for both beams (IQC latched mainly for B1 transverse losses)  108 bunches circulating  beam dump due to vacuum in point 7
Injection of batches with 36 bunches for both beams  OK, losses for B1 at about 50% of dump limit, better (25-30%) for B2.
