Week 44 - Parallel MD

Wednesday 31/10 (12:00 - 18:00) - Comparison between the orbits in the SPS with 25 ns and 75 ns beams

Beam conditions: PSB user = LHC25A&B or LHC75A&B, PS user = LHC25 or LHC75 and SPS user = MD1

Contact person: G. Arduini

Thursday 01/11 (08:00 - 18:00) - Measurement of the SPS low-frequency inductive longitudinal impedance

Beam conditions: PSB user = MD2, PS user = MD4 and SPS user = MD1

#bunches = 1

N_b = 1.3 x 10¹¹ p/b (i.e. nominal intensity, possibility to decrease it => Preferably with the vertical shavers in the PSB to preserve the longitudinal emittance)

Transverse emittances: e^* ~ 1 mm

Longitudinal emittance: e_L^* ~ 0.2 eV.s

Contact person: E. Shaposhnikova

Friday 02/11 (08:00 - 13:00) - Study of the fast vertical single-bunch instability at SPS injection

Beam conditions: PSB user = MD2, PS user = MD4 and SPS user = MD1

#bunches = 1

N_b = 1.3 x 10¹¹ p/b (i.e. nominal intensity, possibility to decrease it => Preferably with the vertical shavers in the PSB to preserve the longitudinal emittance)

Transverse emittances: e^* ~ 1 mm

Longitudinal emittance: e_L^* ~ 0.2 eV.s

Contact Person: B. Salvant

Friday 02/11 (13:00 - 18:00) - Localization of the SPS transverse impedance

Beam conditions: PSB user = MD2, PS user = MD4 and SPS user = MD1

#bunches = 1

N_b = 1.3 x 10¹¹ p/b (i.e. nominal intensity, possibility to decrease it => Preferably with the vertical shavers in the PSB to preserve the longitudinal emittance)

Transverse emittances: e^* ~ 1 mm

Longitudinal emittance: e_L^* ~ 0.2 eV.s

Contact Person: R. Calaga

Note that the parallel MD1 cycle in the SPS might be used also (if needed) during the week-end to finish all the above measurements!
