"Multi-purpose" T2 wobbling



This is the "multi-purpose" T2 wobbling setting. B1 and B2 is calculated in order to have the directions of the protons to point in between H2 and H4 (before being bent in B3) i.e having an angle of 11.2/2=5.6 relative to the axis.We then get:

	B1=	12.6/15.582*5.6		=4.53 mr
	B2=	5.6+4.53		=10.13 mr
B3 is set to bend +150 GeV into H2 and -150 GeV into H4 at 0 production angle (i.e 5.6 mr deviation). The sign of B3 can of course be changed to give positives into H4 and negatives into H2.

  1. This setting of the wobbling station can be used for secondary pion/proton in both beams in the range 100-375 GeV. There will only be 0 production angle at 150 Gev. Chosing 0 production angle at an energy higher than 150 GeV would imply that the protons would be dumped to close to the tax hole and a lower value would give to high production angles at higher energies.
  2. Muons can be obtained from the same secondary beams by offsetting C8 and C9.
  3. The above settings can also provide electrons at - 4.5 mr.
  4. Low energy hadrons can be obtained from decays of kaons and lambdas.
