Change of supercycle => ION-L18000_V1 (18 s long, 15 BPs) => Please try and prepare the supercycle during the preceding shift!

Timing sequence Name => LHCION-0/2/3

Beam conditions: LEIR user = EARLY / PS user = LHCION / SPS user = LHCION (RF MMI pointing to LHCION => See below how to do this)

RF MMI pointing to LHCION (method):

            - Working Sets

            - RF-MMI => SPS-MMI

            - Select context => SPS.USER.LHCION

            - View => Show devices description

- MMI target LHCION => Enabled and MMI target "previous one" => Disabled. To be done 2 times as it appears 2 times in the list

- Delay has to be set to 550

- Only 1 user (LHCION) is used for the parallel MDs and the dedicated ones: All the timings (CBCM Timings, RF-SPEC, RF-MMI and EA-NORTH) have been saved in the archive "LHCION for parallel MD" for the parallel MDs and "LHCION for dedicated MD" for the dedicated MDs => Load the correct archive when needed.

- Note that the timing SIX.MC-CTM is Enabled with a CCV of 425 (ms) for the protons, while it is 525 (ms) for the ions as they are extracted from the PS 100 ms later than the protons.

#injections = 1 with 1 bunch - Extraction from the PS w/o QKE58

N_b = 1.0 x 10¹⁰ charges/b

Transverse emittances: e^* < 1 mm

Bunch length (4 sigmas): t_B = 4 ns.

Longitudinal emittance: e_L^* < 0.05 eV.s/u
