M13 Operation - TWIST

Beamline Control

• Adjusting M13 with EPICS
• Fundamentals of Slit/Jaw settings (including their effects on range spread, momentum bite, etc)
• F0 Slits and Jaws, procedure to set them more reproducibly, and their effect on the muon rate
• Monitoring B1 when the NMR won't lock

• The B1 and B2 field regulators (which correct for drift in the field) are controlled by slow controls.

• Adjusting M13 with TICS (obsolete)

Beamline Information

• Overview of the M13 beamline.
  • B2 Cabling Diagram

• Results of the 1 October 2002 scan of B2.

• List of M13 F1 absorber wheel positions

• Particle Times of Flight from 1AT1 to the M scintillator, as a function of momentum. (You can also use the perl program ~e614/perl/tof.pl (read that file for usage instructions).)

• FYI, the M13 beamline is 8.369 metres from 1AT1 production target to the centre of Q7. From a scale drawing of the TWIST front end, it is about 1.96 metres from the centre of Q7 to the M counter.
