The BL4S project has access to the T9 beamline in the ProtonSynchtron EastArea. The T9 beam is a secondary beam of hadrons and leptons. It has a maximum momenta of . The ProtonSynchrotron delivers protons on target over a spill length. This produces protons, pions, kaons and positrons in the positive beam, pions, kaons, electrons and anti-protons in the negative beam. The amounts of these species in the secondary beam are shown in [1].


Particle fluxes are listed in the attached files: Note: "The rates in the T9flux graphs are estimates and some (in particular pbar) are quite arbitrary)". Rates are given per spill, i.e. distributed over and are listed with the widest collimator settings (). Rates should scale linearly with collimator settings.


The PS and SPS schedules are online at:

BL4S2015 is currently allocated September 9th - 20th.



  • To see the cycle of shots - look for EAST_NORTH for shots on the target upstream of T9
East area
  • To see profile of shots on the target


Had training on Zone Patrol and Beam Control with LauGatignon on 2015-07-16.

Need to request access to:

  • "Zone patrol rights (bldg 157) - T9 (EH-T9)"
  • "Control Room T9 (0157-R-012)"
Remembering to attach the "Attestation East Area Patrol Rights" form, signed by Lau.

Note that the old version of Cesar needs to be used to control the MagneticField in the experiment zone.
