Various tests are planned during the 15h00 shift:

• Test of beam flags
• Test of SMP flags
• Test of post mortem events
• Handshare with the experiments

• Experiments ALICE and LHCb will be closed.
• A serious of TED shots with "probes" (5-10 x 10⁹) will be executed.
• The frequency will be not higher than 1 shot per 30s.
• The shots are inserted in bucket 1.
• ALICE will take data during these shots, LHCb not.

From now on only controlled access allowed to the experimental caverns. This means access needs to be requested via e-mail to Rossano Giachino and the access will be discussed in the daily 8h30 meetings.

First probe bunches will be inserted into the LHC and threaded through the machine. Of the order of one/afew splash(es) is/are expected in the experiments during this operation. The machine-mode will be "Setup Beam", the beam mode will be "Injection Probe Beam".

A series of SPLASH events (O(10) per side) will be given to the experiments ATLAS and CMS for commissioning purposes. (bucket 1 for beam-1 and 2001 for beam-2; starting around 10:30 am)

To further commissioning LHC the Dipoles of the experiments need to be switched on to control and correct the kicks due to the magnetic fields during the various phases of the machine cycle.

The beams will be ramped. These collisions can be used parasitically by the experiments, 2 nominal bunches colliding in each IP (+ a few probes non-colliding). Relative luminosity information requested by experiments.

Experiments try to determine the IP position and give feedback to the machine within 24h. The quiet beam will be done with aligned TCTs. The settings are not yet validated with loss maps. The beam will be ramped and squeezed with 3 nominal bunches.

This exercise is before a shutdown of the injectors. Filling will start in the night around 4am. Quiet beams will be finished probably around 10h00. CMS will repeat the exercise to separate the beams after one hour of quiet beams for approx. 30min. This will allow to see if the difference in z-position of the beamspot which was observed in the quiet beams on the 11th of April can be reproduced or not. ALICE also wants to run some time with beams separated.

These checks re-measure and, if necessary, address the limitation in B1V on the L side of IP1.

Details to be defined.

The intensity ramp up for 2016 starts. After three days a scrubbing run for four days is foreseen.

• 1 cycle with pilots
• 1 cycle for outstanding loss-maps (End-of-Squeeze + with TOTEM bump)
• 1 cycle with 3x3b into SB, can be very short: Filling scheme: Single_3b_2_2_2

• 49b fill: Filling scheme: 25ns_49b_49_36_36_12bpi_5inj
• Insertion of TOTEM (15sigma+500 margin), AFP (20sigma) after 2hours. At end of fill TOTEM should be inserted to 15sigma with no margin for ~30mins (to be done in Stable Beams).
• LHCb will try to do ~2hr SMOG test during this fill which is seamless for machine/other-experiments

• 86b fill: Filling scheme: 25ns_86b_74_47_49_12bpi_9inj
• Includes 2 well isolated bunches for ATLAS after-glow study (shift crews for SPS and LHC should be pre-warned that this contains injection of an INDIV in the middle of the scheme).
• TOTEM/AFP can be inserted (with margin) if they want (assuming no problems in previous insertions).
• If LHCb SMOG test was not done in previous fill it should be done in this one.

• 3 x 300b fills: Filling scheme: 25ns_313b_301_276_276_72bpi_7inj
• For second fill insertion of TOTEM (15sigma+500um margin), AFP (20sigma) after 2hours (assuming no problems in previous insertions).
• For third fill TOTEM/AFP can be inserted (with margin) if they want (assuming no problems in previous insertions).
• During one of these fills want to carry out MD1224 (pressure increase around IP1/5 for beam background studies) for ~2.5 hours (stay in Stable Beam). Expert availability Saturday afternoon or Sunday day.

• 3 x 600b fills: Filling scheme to be defined (will be with 72b trains).
• For second fill insertion of TOTEM (15sigma+500 margin), AFP (20sigma) after 2hours (assuming no problems in previous insertions).
• For third fill TOTEM/AFP can be inserted (with margin) if they want (assuming no problems in previous insertions).
• During one of these fills ATLAS may ask for lumi-levelling at mu=0.1 for AFP run (needs confirmation on allowed separation in IP1 from rMPP).

VdM scans for 2016 data taking. Two days are foreseen for the completion of the scans. Details of the setup are availble in this talk. Proposed filling schemes: Multi_51b_8_27_16_4bpi14inj_alt (for IP2/8 scans), Multi_56b-52b_32_16_8_4bpi14inj (for IP1/5 scans).

VdM scan for CMS (and one scan for ATLAS).

Technical Stop 1, followed by 2 days for re-commissioning/validation.

3b fill where the effect of different AFP/TCL settings on the ALFA radiation will be studies ~2hrs.

mu-scan in IP1/5 (+/-2sigma per beam in out-of-crossing-plane). (~45mins each not at same time). (requires 2 isolated INDIVs in filling scheme).

Beam background pressure test MD for IP1/5/2 (602b filling scheme). (same fill as above). (During stable beams). (~3hrs).

The first day dedicated to set up the 2.5km β* run. Will probably include 2hrs of tests of background for TOTEM/ALFA as a function of collimator positions.
