+==== Some questions from Lecture 4 (Berg):====
+  * 1) How does COSY calculated the fringe field?
+  * 2) How important are accurate fringe field measurements for SECAR and St. GEORGE?
+  * 3) What is the meaning of the rectangles in  COSY graphics output?
+  * 4) In an achromatic fragment separator, do you need a slit and/or a wedge in the dispersive intermediate plane.
+  * 5) In a gas filled separator are all charge states collected in one location?
+  * 6) How does a wedge restore the achromaticity in a fragment separator?
+  * 7) What is the purpose of the DSR (Spin dipole) in front of GRAND RAIDEN focal plan?

+==== Some questions from Lecture 5 (Berg):====
+  * 1) Why are there 189 Characteristic Rays (see Procedure CHARAY)?
+  * 2) How realistic is Gaussian distribution for the incoming beam?
+  * 3) Difference between dispersive focus and achromatic focus.
+  * 4) On ST. GEORGE the reactions that push the energy acceptance (+/-8%) also pushes the angular acceptance (+/-40 mrad). This doesn’t seem to be true in SECAR: 15O(p,g)19Ne pushes the energy acceptance (+/-3.1%) but not in the angular acceptance (only +/-15.6 mradvs. SECAR’s +/-25 mrad acceptance). Is there a reason SECAR was designed with angular acceptance so much larger than the energy acceptance?
+  * 5) Purpose of SECAR Section 3?
+  * 6) On slide 6, what is the meaning of the arrows the Effective Field Length and Good Field Regions?
+  * 7) Extended target for SECAR?
+  * 8) Engefunction (not from this Lecture)?
+  * 9) Is Q1 (Quad + Hex) used or only a design feature?
+  * 10) x_HO= (x’|x)*2_0 + HO, how are the higher order terms (HO) added
+  * 11) Clarify D in the definition of the Nominal Beam definition
+  * 12) Why is the alignment adjusted before and after the ion optical element?
+  * 13) Can the recirculatory-ring for projectile beam increase the nuclear reaction rate? I.E. can we return the projectile beam (passed through the target) to the beam again.
+  * 14) Alignment example not clear.
+  * 15) Does higher order effects give us details about the initial beam characteristic? Or do HO effects tell us that the beam line is different than what we think? ( e.g. field imperfections in the magnets etc.)
